It's time for another engine teardown! Although Subaru didn’t invent the boxer engine, they perfected it. Powering the Impreza WRX, STi, and Subaru WRC rally cars, the EJ boxer has collected millions of fans worldwide. Today we're diving deep to see what’s so special about Subaru's famous EJ platform.

16:22 NO! That is not top dead center. The timing marks line up at about 90 deg from TDC so the pistons are halfway down the holes and you can spin the cams around to get them timed. That's the ideal place to have it while disassembling.
240,000 miles on my manual transmission 2009 Impreza 2.5i wagon. I've fallen on hard times with health problems and have been homeless and living in it for 3+ years. Having a wagon has saved my life
EJ205 in 2000 SF Forester GT. Clicked over 405000km still original everything even turbo it seems! Still gets 9.5 l per 100 km fuel economy and will only puff a touch of valve stem seal smoke if you haven't started it for a couple of weeks. Sounds cool as
@@ajchilds2163generally not, at least in the US. The whole reason Subarus are notorious for their head gasket issue is because for a number of years on specifically the naturally aspirated models, they used a crappy paper-like head gasket. On all the turbo models they use metal ones which are very rarely prone to failure. As soon as Subaru started putting the multi layer head gaskets on the n/a cars, the issue went away
@copperwolf8792 OK I didn't realize they had different engine with the turbo and na and ik na have shitty head gasket I just did a gasket job on subaru I bought there eas huge diff between oem one and the felpro I put on
I am glad to hear this, I just bought at 2000 Forester S/tb (turbo ej205) with 120,000km. Doing the timing belt, tensioner, and pulleys next weekend even though the belt looks brand new.
I used to work as a professional automotive technician and Subaru timing belts were among the easiest and most profitable for the technician. These are substantially easier to do than most FWD cars. I almost always pulled the radiator to do the timing belt, since it takes about 15 minutes to do and gives you tons of room to work. The only part that sucked was on the dual cam AVCS versions, the bolts holding the cam gears to the cams like to self-tighten and can be really difficult to remove. This makes replacing the cam seals (which should be done with every timing belt) a bit difficult. The drivetrains on EJ Subarus are actually brilliantly simple to work on compared to most AWD tuner cars, especially vs something like an Evo or DSM. Pulling the engine takes a couple of hours, so if you have to do more than 2 jobs on the engine (or anything involving removing the heads) you just pull the engine.
I always wondered if pulling the one brine/removing stuff from the car made a technician’s job easier than just directly tackling the task at hand. Thanks for the input! I’m a new FA20 owner and I’ve been working my way up to doing an engine pull wventully so I can change out my pistons and rods
I remember the Subaru's that the late great Possum Bourne ran Australian Rally Championship in the mid to late 90's and early 00's sounded awesome, not to mention that he was one of the finest rally drivers in the world. Just as spectacular as Colin McRea IMO. His Legacy and WRX's were all Prodrive from memory. Halcyon days!.
As a fun detail: this was the first timing belt I ever did. Went well until I went to put coolant back in and realized the gasket fell out of place on the water pump… So I did it the first time… twice.
@@hughtenhove867 at least on the sohc motors it's a pretty simple job in my eyes. If doing in the car I just remove fans as long as I'm not doing water pump at the same time. If doing water pump as well, just take the radiator out too and give yourself more room.
I have a EJ207 sti that I've owned for 15 years. I would drive it 3 hours to the track, drive it hard all day then back home! 200k's and going strong😁 I love it!
Hell yeah, most of the hate come from folks throwing on modifications without doing a tune. Mines only tuned to 305 on pump gas, not a lot of power at all, but fun on the rally cross courses.
Nearly 150,000 miles running 370bhp on an open deck wrx, and it had never had a rebuild and ran anti lag and launch control. What killed mine eventually was a failed oil pump took out the bearings. These engines are very reliable if looked after and serviced correctly and use high quality parts…
EJ205 which is in New Age WRX I wouldn't run above 350bhp without forged internals,you are been lucky to run above that for such long time,we have run 490bhp on EJ205 stroker and then went with EJ22G and stroker 2.35L which I would say is one of the best engine Subaru ever built For money EJ205/207 are best for bang engines with forged internals and you are looking at reliable 500-550bhp on open or semi closed decks,not sure if I would run above that figure semi closed deck For high power builds most of UK builders prefer EJ22G(which was used in 22B) and in US on other hands closed deck EJ257 are used although I still prefer stroker 2.35L,have run both 2.1L or 2.5L and 2.35L is way best in my opinion but agree servicing with OE parts and mainly not skimping on parts is best
16:27 scotty mentions having the engine on TDC to show timing marks, then mentions how he wound it over to move it off to avoid any piston to valve problems. Fun fact the timing marks for an ej are actually at middle stroke on all 4. You're nowhere near the pistons. You can still have valve to valve interference though so you do have to pay attention to which way you rotate the cams.
I just saw your comment as I was about to say about the same thing. With the timing mark for the crank at 12 o'clock. You can rotate the cams without hitting the pistons. In that position the valves on the right head are close but not the left side.
Proud EJ257 owner. My initial EJ255 in my legacy did 348000kms before open boost took out a rod bearing, would have kept going otherwise. Good servicing goes a long way
I love EJ's, I think they are super easy to work on, rebuilt my whole EJ205 in my garage with basics tools which is 1 thing I like, you don't need any specialist tools to take these apart and rebuild.
Gotta say, i don't understand these head gasket failures that haunt Subaru, my WRX hit 367000km and it still has original head gaskets, not eating oil or no knocking noises. It has been miracle engine so far.
IIRC the head gasket issues were from the SOHC engines that used inferior materials. If you replaced the head gaskets with the metal gaskets found in the turbo engines, those engines were good. It is too bad that it was assumed all Subaru engines had head gasket issues. I still hear it to this day... even with late model cars.
My 99 wrx, 268km, just replaced gearbox, just replaced original starter. Still has original alternator, has been so reliable, regularly gets spanked and loves it.
Hi. I have a 2005 wrx ej20. The car has done 216000km now and I have never touched the engine yet except for services. Never even had a engine light on in 19 years. Fantastic little car.
Fun fact: Unlike most engines, EJ Cam Drive Belts are not clocked at TDC. The crank is at 90° half way through the Cylinder 1 Combustion stroke when all the marks are lined up. Every other piston is also half way through its respective stroke in order, 3 is halfway through Compression 2 is halfway through Induction 4 is halfway through Exhaust All of the right bank valves are tight shut. In the left bank Cylinder 2 Intake valves are wide open, and Cylinder 4 Exhaust valves are wide open. Removing the belt almost always resulting in the left bank valves slamming shut. It's very important to return the left bank Exhaust valve to its timing position by turning the cam counter clockwise so that the Cylinder 2 Exhaust valve does not clash with the open Cylinder 2 Intake valve.
My 92wrx is making 850 WHP. It has PPM rods, JE ultra pistons, heads are gasflowed with some combustion chamber work. Bee hive springs and titanium retainers from kelford. custom exhaust and turbo. It has a 9200rpm rev limit, its on 10PSI at 4200rpm and 40 psi from 4800rpm all the way till redline. It starts to run out of cam at 8500rpm but it will rev on to redline no problem. It is still using a factory ECU...lol. The engine is now 2 years old and has done many track days too, still good as gold. Its a great car to drive, crazy fast and it grips like hell... just brilliant!
I got a 1 owner 02 wrx and its about to hit 200,000miles. Its been the most reliable car I've owned. Its still daily driven and has only needed your average maintenance its whole life.
Love my ej25 , close to 360 k on it now , had head gaskets and an arp stud kit around 100k ago due to small compression into coolant leak - runs like an absolute champ still though with a vf34 @ 19 psi … I rate em 👍
My self and my girlfriend are both Subaru dealer techs in the states, and the Ej definitely has a soft spot in my heart. I have an 05 Wrx that is both my daily driver and my Rallycross car and the fact of the matter is my girlfriend is the one who rebuilt the engine that currently gets absolutely punished. I love the Ej for its quirkiness but simplicity. I also love the newer chain drive F series engines, but there's just something about the Ej. Love the video Haltech!
I have a North American 2002 WRX Wagon with the EJ205. It's got 168,000 miles on it currently and still going strong. Had an experienced Subaru tuning shop do the timing belt and water pump for me a few thousand miles ago. I love this car. Pretty sure if the motor blows up I'm just gonna slap another EJ205 in it. Either that or buy another GD chassis WRX. Definitely the best car I've ever owned. I have mine lifted with skidplates and inverted rally style coilovers plus some A/T tires. It's not the best off-roader, but man, it can really rip down the desert washes we have here in California. I think I also have the only high-mileage WRX in the world that doesn't burn oil lol. In short, this car has never let me down. I love it.
I have a 2000 Impreza OBS with 407k miles. Original engine, original manual transmission. The EJ22 was an absolute masterpiece of reliability. That car has taken me through sand dunes, icy roads on the side of a mountain, through flooded roads during a monsoon, 3 feet of snow, it doesnt stop. I absolutely love Subarus and all they are capable of. My weekend car is an 08 WRX STI. It only has 80k on the clock. The only issue I've had is the turbo springing an exhaust leak, which i replaced easy peasy.
They are a masterpiece if maintained correctly. Ive got a 05 STi with original 207 and 265,000km later still running strong asf. Not a drop of oil or any issues.
@@mircebob yeah that works for me as well. Proper warm up and cooldown, regular oil changes 5 to 7k kilometers and don’t floor it on heat soaked top mount intercooler / high intake temps and always put in high octane fuel which it’s mapped on. And a proper mapping
I think a majority of the issues involving a head gasket failure, revolves around Subaru not using the multi layer, graphite coated (I think), gaskets in the EJ engines during the early 2000s. They soon realized it was mistake and fixed it after the fact.
I would love to see a video on the FA20! I recently got a 2020 WRX and would love to see a similar video about that engine! great work guys very informative and i appreciate you doing this
Me too! I have a 2017 WRX and I got it specifically because the improvements they made like direct fuel injection. I’m eager to see where the shortcomings are the the FA series engines
15:53 for anyone interested in doing their timing belt on their EJ, it's actually not super difficult. It's definitely a hard job, but having an extra set of hands really helps and you really need to take the radiator out to give you a lot more room to work.
Our 2008 Subaru Legacy had the EJ20 engine, never had a more reliable car ever! this thing took us from Oslo to Chalkidiki! it clocked over 500k kilometers without a single problem! still have it to this day.
I've got a 2000 legacy blitzen EJ 20 done over 230 thousand km Never had a problem doesnt blow smoke or use any oil between oil changes still sounds tight and quiet when running and switched off....I use high quality synthetic oil and factory filters most reliable car I've ever had and still have it today
I have a 2004 JDM Forester STI with an EJ25. Mine is Standard internals and currently running. 372bhp/400ftlb, this is just with Minor Bolt ons. I've had it 5 years and after a major service and a few repairs when I first got it the only repair it needed was the rocker cover gaskets doing. EJ's get a bad rap for reliability but I think that is mostly because a lot of the owners beat on them without looking after them. Mine is always warmed up and I change the oil every 3k miles. I think the most important thing for the longevity of tuned EJs is heat management. Mine makes great power and has been reliable I think because I have a lot of focus on cooling, i.e. bigger rad, heat tape, exhaust blanket, Turbo Blanket, bigger intercooler etc. Have also fitted the intercooler Sprayer of the JDM Impreza STI and have have built and programmed a controller using an Arduino to control it. Just need to fit the temp sensor I have and it is good to go, the only problem is the bung where the sensor should go is stuck in. So that is on hold right now.
My 02 wrx wagon has 227k miles and it's on the original engine, transmission, head gaskets, etc. I beat the crap out of it daily and it doesn't consume or leak any fluids whatsoever. It's just been a great car over the past 3 years!
I'm very appreciative of my EJ25. I have one in my 01 Subaru Forester. It's got 252,000 miles on it, going strong. No check engine light and only burns about a half quart of oil every 5k miles. It doesn't have much power, but Ol' Reliable gets me around no problem. Only mods I have are to my electrical system to run some beefy audio.
Full time Nissan fan boy part time subaru lover here. Wow that was a cool episode, it just gave me an even greater appreciation for EJs. Iv got a sh fxt as a daily, it does 1000kms a week with 270km on the clock with the original engine & full log book service history. It has a few mods Sti intake Vf46 Full turbo back exhaust Gfb response Gfb fpr Ecutek Tuned make 300hp 450nm @3000rpm Thing does street duties then gets going on the sand dunes I cant really fault it
it´s such good timing you did an EJ. I bought a 2007 Impreza NA with the EJ20 in it and i love that thing. Bought it as a family car daily with 180kkm on it. I´m so relieved to read all those comments here which say they run those for well over 300kkm with good maintanance and a bit of love. I so hope my one makes the 3 on the first digit in the future. planned to keep it till my kids go to school (wife is pregnant) And thank you Scotty for the in depth look and well made explanation on how they work.
On an EJ engine, when all the timing marks are lined up, it’s actually not TDC on Cyl 1. All 4 pistons are in the middle of their stroke. Also, on the LH head, you want to use a tool to hold the cams in position while you take off the belt so the valves don’t hit eachother.
Fell in love with Subaru circa 2002 when my coworker gave me the keys to his brand new WRX off the showroom floor for a weekend. Since then have owned several. Currently driving 99 GC widebody.
I just love the EJ They make nice Power and when kept UEL they Sound so damn special. Almost like a poor mans Muscle car (im germany, so big engines are crazy expensive to run here) I actually prevere the Ej257 over the 207 even when they are problematic. Studs, haedgasket, downpipe+exhaust and a good Custom tune gives a relatively reliebale 350hp but with very good midrange torque wich is a blast to drive here in the alps.
That's actually why Subaru Japan keep producing the 257 overseas vs the 207. While still mountainous, Japan has significantly less average road height/elevation than US, Europe, which have higher altitude roads and steeper slopes.
@@impreza0109 While this is all true, a modern turbo will spool up quicker and stay spooled up for longer than what Subaru were working with in the 90s, and more boost means more torque. I drive a 2.5GL NA, but i've driven the 20 and 22 NA as well, as TLDR the 2.2 is the best. It's quick to rev high like the 2.0, but has power like the 2.5, it's really the perfect engine.

Are we not going to talk about how this was a VERY WELL DONE, AND DETAILED video.. this dude tore a boxer down completely and then at the end said "so there's the basics"
Loved my 2017 STI. 5 years of great ownership from track days to spirited driving with zero issues. Back to the basics with the new 2022 BRZ. Great video Thanks.
My dad's 1983 Subaru GL wagon was purchased new in Louisiana, shipped to Germany, California, Italy, and then Texas, due to his US Air Force service. Over 200k miles on the manual, carborated, FWD station wagon, which 19 years later was still running and became transportation for a college kid for $1k. I now have a 2018 6MT Forester, getting 30 mpg in Cleveland Ohio. I can't speak to the CVTs or the future of the company, but so far, I love my Forester and would buy another.
Gone thru 2 motors so far, 2 open decks and on my first closed deck now. I love these motors. I beat the crap out of it every time I drive it. Very fun cars to drive
Awesome vid 🤘I bought and still own a 04-05 n/a 5speed Impreza RS 2.5 new from the factory about 18years ago, having the scheduled maintenance done. Proud to say it still runs like clockwork 😉👍
I've got an EJ201 that's done 377xxxkms and is still going strong. Its an N/A SOHC non variable cam model so less to go wrong, the single cam allows for more porting of the heads for better flow so it has great low end torque for a 2L 4 banger. Helps that it's in an 1150kg 4wd GC8. I seriously reckon this thing will make it to half a million the way its running.
The head gasket issues are due to the composite gaskets used only on the NA engines. Subaru bought a stock of several hundred thousand of them in the early 90s. But the composite head gaskets were NOT used on the FI engines as it was known it wouldn't hold up. Luckily, the differences between the heads and block are minor (so long as you stick with "like for like", so an EJ25 head on an EJ25 gasket on an EJ25 block+piston and conrods), so there's no problem putting an FI MLS gasket on an NA head and block. In fact, it's encouraged.
Lovely video Haltech. I’ve replaced many head gaskets on NA ej’s in the past. Up until mid 2010, the factory was using a broken piece of rock in the fly cutter, you could feel the imperfections in the block decks. The OEM gasket pn 11044AA633 helped deal with this, and for some odd reason the factory swapped to MLS gaskets 6 months before introducing the FB25. Cometic wants the surface's finish RA to be
I have a 98 2.5rs and I literally did my head gaskets in my garage with a piece of glass, multiple grits of sand paper, wd40, a lot of patience and counting passes, at the same time cleaned up and rebuilt the heads, I have now been driving it for 2 years daily with no issues. These things aren't hard to work on and they can be reliable if taken care of.
My EJ25 is the first engine I've ever done a timing belt one. Getting in there with everything in the way was incredibly fun! Quick tip tho, you can just remove your radiator fans/shroud and it gives you enough room to do the service without having to drain the coolant. Highly recommend having all of the specialty tools to do this job tho. Company 23 is a life saver!
Thanks Scotty I watch a lot of your work but I ve owned 3 Stis and 5 wrxs that my family drove..all tuned with bolt ons.no issues the way they were tuned and serviced..my fav was my version5 Sti...I've travelled all over Australia.. tracked my Stis even towed a ski boat absolutely no issues except the normal wearing parts and my version 7 had a fuel pump relay fail just love them still have my 2002 its immaculate
My dad has a 2008 EJ20 Impreza with 370k km on it, still runs like a charm, gonna have the engine and trans rebuild before it gets passed down to me though, can't wait
i really love EJ engines, i already have 2 of them, one EJ25D with a new short block, and one EJ204l original with 310000Km. still works as the first day
Tuned EJ257! 300,000mi on the odometer - ~150,000mi on the engine and transmission in my 05’ LegacyGT wagon. She’s had some overheating issues (upper radiator hose getting to close to pulleys/fan blades, but she’s going strong!
17 psi of boost in sport and 27 in sport sharp with stock heads , open deck block with forged pistons and rods- beating on it on the Dragon , did autocross ( out of 43 cars had the best time , prepped Corvettes , stock miatas , automatic bmws , supercharged quattro audis , brand new M3) - and it has been 55K miles over the past 5 years. 5.0 V8s can not touch it. Grateful for this unique and reliable engine.
I use to own gtr but once I bought a wrx I fall in love ❤️ with it right away they are unique and sounds amazing thanks for the video it was amazing content ❤
I've got an 02 forester, EJ205 with bolt ons tuned to 186kw atw (18psi), it was 100kw atw when it was stock. Its been that way for 10 years and 70000 km and has been completely reliable. Look after them and they are solid little engines, It would have been good to note how the cam cover seals, particularly on the drivers side are notorious for dripping oil onto the exhaust.
Love my ej207 pushing a lazy 240kw atw on 22psi on 98 Street tune in my wagon but iv gone overkill on turbo setup n fuel system for e85 n more power love the torque and how smooth it is
One of my all time favourites is the EZ30, great to dismantle! Similar to the EJ platform but with a few extra components and some differences such as variable valve lift and timing chain assembly. So much more but you get the point.
They leak oil, make good power and they blow up lol.. and even so, we still love them. Why? They're super easy to work on, (except for replacing the spark plugs), and they're like Legos, mixing and matching parts from WRXs/Foresters/Outbacks & STi. I don't think any other car brand is easier to mix/match its parts. My very first Subie, an '01 Forester SF, I partially rebuilt its motor fixing the H/Gs with MLS ones, the motor never leaked again. Even since, I was hooked on working in these cars and did everything on it. Provided you take care of the EJs, and address the common issues like oil starvation with a better oil pick up tube, catch cans for the PCV system, the Cylinder 4 cooling, and not over boosting them, these are great all round cars that will last a long time and will be plenty of fun.
I'd love to see a teardown on the VQ35DE! It's not the most popular motor but they have tons of potential and are probably one of the best V6 on the market
I had a stock standard 2004 Subaru Impreza with an EJ20 motor in it. Absolutely most reliable car mechanically I’ve ever had performance was good never lost a drop of oil after 10 years you could eat off the top of the motor it was so clean I did service it and change oil every 5000 km because I’m fussy - I’ve done that with all my cars they have a bit of an issue with liking upper cylinder clean because of carbon collecting due to the design or something like that but absolutely reliable never overheated spot on cooling system for stock standard, absolutely reliable….. Prior to that I had a 2 L honda Prelude the Subaru motor was better…….. The only component that ever had to be replaced outside servicing was a knock sensor, which threw up an engine light, and I drove that car for 15 years
My dad always told me there was a in-line six cylinder Ford in the cargo vans of the late 90s early 2000s that is absolutely bulletproof. Unfortunately I’m not a car guy so I don’t know the exact one but in the video you said if we want to see a tear down ask for it so that’s what I’m doing. Great video
I have an EJ25 in my 09 WRX, did the timing belt at 100k myself in my garage with the japanese Gates kit. Took some time but I removed the radiator to do it. I'm the second owner and afaik it's never been split, consumes zero oil. I do baby it though. It is my first subaru and I love the sounds.
Good stuff Scott, been waiting for this one 😛 Plenty of EJ207's around after 2005 also, I have a 2009 GRB spec c with a 207, most of the factory backed race cars and S20x variants etc. were powered with the 207, pretty sure you can still buy a brand new 207 'crate motor' from STi in Japan
My current daily driver is a 05 Legacy Wagon with a turbo EJ and a 5-speed in it. I love it because it's fun and quick and yet gets 0 attention from law enforcement since it's a stock(ish) looking wagon. As far as I can figure, it's putting out about 300 American HP with the mods done to it. It's not the fastest thing I've driven, but it is a fun daily driver. I'm just glad to be keeping a 17 year old car on the road and out of the junkyard. It has a short list of stuff it needs, but I'm working on it. Thank you for the video. I always like to see differences in how people take things apart. I pick the method that works best for me.
When I was living in England over ten years ago I went to a festival that had cars, a market and bands. I got to see the restored Colin McRae 555 car full noise around the track. Was one of the best things I’ve got to experience!
i love my ej motort but props to the transmision thats behind it i blew the rear housing bearing up at subie fest it still got me home 2hours and 45 minuts away 85 miles and drove for a week after till i put it on jack stands and fixed it
Great video Scott, happy you guys made this. Ive got a 09 forester xt stage 2, the ej255 is doing great at 176ks. 6month oil changes keeps her happy. The pcv system on these could be a whole other video and plays an important role in engine longevity.
I just recently finished a rebuild (well, not me but for my GC8) and so far very happy with the current setup! It's an EJ20G closed deck block with a 2.5 crank and CP stroker pistons (so 2.14 displacement), built non-AVCS heads with 272 Kelford cams and all the Ferrea goodies to go with it 😬😬😬 Very responsive and very fun for the street but it is an old block so there's quite a bit of blow by and pressure in the case and heads. All running with your Elite 1500 ECU of course 😉
It's time for another engine teardown!
Although Subaru didn’t invent the boxer engine, they perfected it. Powering the Impreza WRX, STi, and Subaru WRC rally cars, the EJ boxer has collected millions of fans worldwide. Today we're diving deep to see what’s so special about Subaru's famous EJ platform.

16:22 NO! That is not top dead center. The timing marks line up at about 90 deg from TDC so the pistons are halfway down the holes and you can spin the cams around to get them timed. That's the ideal place to have it while disassembling.

EJ205 in 2000 SF Forester GT. Clicked over 405000km still original everything even turbo it seems! Still gets 9.5 l per 100 km fuel economy and will only puff a touch of valve stem seal smoke if you haven't started it for a couple of weeks. Sounds cool as
Do the turbo engines have the same headgasket problems the na does
@ajchilds2163 I think it's the 2.5 litre has head gasket issue but EJ20 2.0 litre doesn't
@@ajchilds2163generally not, at least in the US. The whole reason Subarus are notorious for their head gasket issue is because for a number of years on specifically the naturally aspirated models, they used a crappy paper-like head gasket. On all the turbo models they use metal ones which are very rarely prone to failure. As soon as Subaru started putting the multi layer head gaskets on the n/a cars, the issue went away
@copperwolf8792 OK I didn't realize they had different engine with the turbo and na and ik na have shitty head gasket I just did a gasket job on subaru I bought there eas huge diff between oem one and the felpro I put on
I am glad to hear this, I just bought at 2000 Forester S/tb (turbo ej205) with 120,000km. Doing the timing belt, tensioner, and pulleys next weekend even though the belt looks brand new.
Stock EJ255 with 286,000 miles still running strong in my 05 Legacy GT!
I used to work as a professional automotive technician and Subaru timing belts were among the easiest and most profitable for the technician. These are substantially easier to do than most FWD cars. I almost always pulled the radiator to do the timing belt, since it takes about 15 minutes to do and gives you tons of room to work. The only part that sucked was on the dual cam AVCS versions, the bolts holding the cam gears to the cams like to self-tighten and can be really difficult to remove. This makes replacing the cam seals (which should be done with every timing belt) a bit difficult.
The drivetrains on EJ Subarus are actually brilliantly simple to work on compared to most AWD tuner cars, especially vs something like an Evo or DSM. Pulling the engine takes a couple of hours, so if you have to do more than 2 jobs on the engine (or anything involving removing the heads) you just pull the engine.
Do enough of those engine removal and can easily be done in less than an hour. At least on the manual na platform
Great info. Please consider making a video on how to get engines out so quickly
I always wondered if pulling the one brine/removing stuff from the car made a technician’s job easier than just directly tackling the task at hand. Thanks for the input! I’m a new FA20 owner and I’ve been working my way up to doing an engine pull wventully so I can change out my pistons and rods
I am just a regular guy with Walmart tools. I am able to do belts, alternator, spark plugs, hoses, and so. EJ 2.5 is gonna hit 300 000 miles
took me a week. bum back , arthritis hands
I remember the Subaru's that the late great Possum Bourne ran Australian Rally Championship in the mid to late 90's and early 00's sounded awesome, not to mention that he was one of the finest rally drivers in the world. Just as spectacular as Colin McRea IMO. His Legacy and WRX's were all Prodrive from memory. Halcyon days!.
Possum Bourne was a friggin legend. As was Solberg who is sadly often forgotten as a Subaru WRC ace.
Possum Bourne's legacy is the shop (Possum Bourne Motorsport) still doing Subaru's in NZ... They even do the EZ30 and EZ36.
ej20g racing engines sound monstrous
As a fun detail: this was the first timing belt I ever did.
Went well until I went to put coolant back in and realized the gasket fell out of place on the water pump…
So I did it the first time… twice.
You just loved that job so much you did it twice. ;-)
That gasket can be a pain.. Last one I did, I went RTV-Gasket-Rtv and it'll stick in place. then you're golden, brother!
SAME, FIRST TIMING BELT I EVER DID WAS ON A EJ 25
doing this for the first time soon, note taken. watch the water pump gasket
@@hughtenhove867 at least on the sohc motors it's a pretty simple job in my eyes. If doing in the car I just remove fans as long as I'm not doing water pump at the same time. If doing water pump as well, just take the radiator out too and give yourself more room.
I have a EJ207 sti that I've owned for 15 years. I would drive it 3 hours to the track, drive it hard all day then back home! 200k's and going strong😁 I love it!
Which year EJ207 do you have?
@@leighton_lam 2001 sti
Hell yeah, most of the hate come from folks throwing on modifications without doing a tune. Mines only tuned to 305 on pump gas, not a lot of power at all, but fun on the rally cross courses.
Nearly 150,000 miles running 370bhp on an open deck wrx, and it had never had a rebuild and ran anti lag and launch control. What killed mine eventually was a failed oil pump took out the bearings. These engines are very reliable if looked after and serviced correctly and use high quality parts…
EJ205 which is in New Age WRX I wouldn't run above 350bhp without forged internals,you are been lucky to run above that for such long time,we have run 490bhp on EJ205 stroker and then went with EJ22G and stroker 2.35L which I would say is one of the best engine Subaru ever built
For money EJ205/207 are best for bang engines with forged internals and you are looking at reliable 500-550bhp on open or semi closed decks,not sure if I would run above that figure semi closed deck
For high power builds most of UK builders prefer EJ22G(which was used in 22B) and in US on other hands closed deck EJ257 are used although I still prefer stroker 2.35L,have run both 2.1L or 2.5L and 2.35L is way best in my opinion but agree servicing with OE parts and mainly not skimping on parts is best
16:27 scotty mentions having the engine on TDC to show timing marks, then mentions how he wound it over to move it off to avoid any piston to valve problems. Fun fact the timing marks for an ej are actually at middle stroke on all 4. You're nowhere near the pistons. You can still have valve to valve interference though so you do have to pay attention to which way you rotate the cams.
^^ Pro Tip:)
That is exactly what I was about to write. Hahaha 👍👍
I just saw your comment as I was about to say about the same thing. With the timing mark for the crank at 12 o'clock. You can rotate the cams without hitting the pistons. In that position the valves on the right head are close but not the left side.
I noticed that too. Also he calls it open deck but that engine was a semi closed
He missed the timing marks that are on the intake & exhaust gears that point at each other.
Proud EJ257 owner. My initial EJ255 in my legacy did 348000kms before open boost took out a rod bearing, would have kept going otherwise. Good servicing goes a long way
I love EJ's, I think they are super easy to work on, rebuilt my whole EJ205 in my garage with basics tools which is 1 thing I like, you don't need any specialist tools to take these apart and rebuild.
Good point
Gotta say, i don't understand these head gasket failures that haunt Subaru, my WRX hit 367000km and it still has original head gaskets, not eating oil or no knocking noises. It has been miracle engine so far.
IIRC the head gasket issues were from the SOHC engines that used inferior materials. If you replaced the head gaskets with the metal gaskets found in the turbo engines, those engines were good. It is too bad that it was assumed all Subaru engines had head gasket issues. I still hear it to this day... even with late model cars.
My 99 wrx, 268km, just replaced gearbox, just replaced original starter. Still has original alternator, has been so reliable, regularly gets spanked and loves it.
Hi. I have a 2005 wrx ej20. The car has done 216000km now and I have never touched the engine yet except for services. Never even had a engine light on in 19 years. Fantastic little car.
Fun fact:
Unlike most engines, EJ Cam Drive Belts are not clocked at TDC.
The crank is at 90° half way through the Cylinder 1 Combustion stroke when all the marks are lined up.
Every other piston is also half way through its respective stroke in order,
3 is halfway through Compression
2 is halfway through Induction
4 is halfway through Exhaust
All of the right bank valves are tight shut.
In the left bank Cylinder 2 Intake valves are wide open, and Cylinder 4 Exhaust valves are wide open.
Removing the belt almost always resulting in the left bank valves slamming shut.
It's very important to return the left bank Exhaust valve to its timing position by turning the cam counter clockwise so that the Cylinder 2 Exhaust valve does not clash with the open Cylinder 2 Intake valve.
My 92wrx is making 850 WHP. It has PPM rods, JE ultra pistons, heads are gasflowed with some combustion chamber work. Bee hive springs and titanium retainers from kelford.
custom exhaust and turbo. It has a 9200rpm rev limit, its on 10PSI at 4200rpm and 40 psi from 4800rpm all the way till redline. It starts to run out of cam at 8500rpm but it will rev on to redline no problem. It is still using a factory ECU...lol. The engine is now 2 years old and has done many track days too, still good as gold.
Its a great car to drive, crazy fast and it grips like hell... just brilliant!
Sounds absolutely mental 😅
@Fozzy10XT cheers mate..
She's had a few more upgrades since then. Pushing 920whp now.
If your ever in New Zealand let me know .
@@gfarnden56 Crazy stuff man, and I definitely will let you know my friend hahah
I tore my first EJ down two years ago and rebuilt it. It was terrifying but exhilarating and it runs! Great vid!
I got a 1 owner 02 wrx and its about to hit 200,000miles. Its been the most reliable car I've owned. Its still daily driven and has only needed your average maintenance its whole life.
Finally, someone that knows. My 2007 WRX is at 199k miles on the original head gaskets.
Love my ej25 , close to 360 k on it now , had head gaskets and an arp stud kit around 100k ago due to small compression into coolant leak - runs like an absolute champ still though with a vf34 @ 19 psi … I rate em 👍
My self and my girlfriend are both Subaru dealer techs in the states, and the Ej definitely has a soft spot in my heart. I have an 05 Wrx that is both my daily driver and my Rallycross car and the fact of the matter is my girlfriend is the one who rebuilt the engine that currently gets absolutely punished. I love the Ej for its quirkiness but simplicity. I also love the newer chain drive F series engines, but there's just something about the Ej. Love the video Haltech!
I have a North American 2002 WRX Wagon with the EJ205. It's got 168,000 miles on it currently and still going strong. Had an experienced Subaru tuning shop do the timing belt and water pump for me a few thousand miles ago. I love this car. Pretty sure if the motor blows up I'm just gonna slap another EJ205 in it. Either that or buy another GD chassis WRX. Definitely the best car I've ever owned. I have mine lifted with skidplates and inverted rally style coilovers plus some A/T tires. It's not the best off-roader, but man, it can really rip down the desert washes we have here in California. I think I also have the only high-mileage WRX in the world that doesn't burn oil lol. In short, this car has never let me down. I love it.
I have a 2000 Impreza OBS with 407k miles. Original engine, original manual transmission. The EJ22 was an absolute masterpiece of reliability. That car has taken me through sand dunes, icy roads on the side of a mountain, through flooded roads during a monsoon, 3 feet of snow, it doesnt stop. I absolutely love Subarus and all they are capable of. My weekend car is an 08 WRX STI. It only has 80k on the clock. The only issue I've had is the turbo springing an exhaust leak, which i replaced easy peasy.
They are a masterpiece if maintained correctly. Ive got a 05 STi with original 207 and 265,000km later still running strong asf. Not a drop of oil or any issues.
How do you maintain it?
Is it anything special I should be aware of?
How do you drive it on a day to day basis?
yup EJ207 is the best, shame Americans got the EJ257
@@hovavrom keep your services on time and let it warm up properly before driving it hard.
@@mircebob yeah that works for me as well. Proper warm up and cooldown, regular oil changes 5 to 7k kilometers and don’t floor it on heat soaked top mount intercooler / high intake temps and always put in high octane fuel which it’s mapped on. And a proper mapping
@@marvinvisser5039 I wouldn't do more than 5,000 KM between oil changes. There was a guy who did his every 8,000 KM and he still spun a bearing.
I think a majority of the issues involving a head gasket failure, revolves around Subaru not using the multi layer, graphite coated (I think), gaskets in the EJ engines during the early 2000s. They soon realized it was mistake and fixed it after the fact.
Only non turbo 2.5 north american EJs got the shit gaskets..
It was a multi layered mls gasket that failed, and this mainly applies to the EJ25 series, they delaminated. The replacements were fixed.
I would love to see a video on the FA20! I recently got a 2020 WRX and would love to see a similar video about that engine! great work guys very informative and i appreciate you doing this
It's like this, but twice as much time due to increased complexity and the timing chain system.
Me too! I have a 2017 WRX and I got it specifically because the improvements they made like direct fuel injection. I’m eager to see where the shortcomings are the the FA series engines
di = carbon buildup
15:53 for anyone interested in doing their timing belt on their EJ, it's actually not super difficult. It's definitely a hard job, but having an extra set of hands really helps and you really need to take the radiator out to give you a lot more room to work.
Our 2008 Subaru Legacy had the EJ20 engine, never had a more reliable car ever! this thing took us from Oslo to Chalkidiki! it clocked over 500k kilometers without a single problem! still have it to this day.
I've got a 2000 legacy blitzen EJ 20 done over 230 thousand km
Never had a problem doesnt blow smoke or use any oil between oil changes still sounds tight and quiet when running and switched off....I use high quality synthetic oil and factory filters most reliable car I've ever had and still have it today
i could watch these all day
I have a 2004 JDM Forester STI with an EJ25. Mine is Standard internals and currently running. 372bhp/400ftlb, this is just with Minor Bolt ons. I've had it 5 years and after a major service and a few repairs when I first got it the only repair it needed was the rocker cover gaskets doing.
EJ's get a bad rap for reliability but I think that is mostly because a lot of the owners beat on them without looking after them. Mine is always warmed up and I change the oil every 3k miles. I think the most important thing for the longevity of tuned EJs is heat management. Mine makes great power and has been reliable I think because I have a lot of focus on cooling, i.e. bigger rad, heat tape, exhaust blanket, Turbo Blanket, bigger intercooler etc.
Have also fitted the intercooler Sprayer of the JDM Impreza STI and have have built and programmed a controller using an Arduino to control it. Just need to fit the temp sensor I have and it is good to go, the only problem is the bung where the sensor should go is stuck in. So that is on hold right now.
Knowing hardly anything about a Subaru motor, THIS is pearler video.
Great stuff
Scottie/tuning fork is incredibly knowledgeable. And has a smooth and relaxed way of presenting the information in a more than friendly manner.
My 02 wrx wagon has 227k miles and it's on the original engine, transmission, head gaskets, etc. I beat the crap out of it daily and it doesn't consume or leak any fluids whatsoever. It's just been a great car over the past 3 years!
I'm very appreciative of my EJ25. I have one in my 01 Subaru Forester. It's got 252,000 miles on it, going strong. No check engine light and only burns about a half quart of oil every 5k miles. It doesn't have much power, but Ol' Reliable gets me around no problem. Only mods I have are to my electrical system to run some beefy audio.

I cant really fault it
it´s such good timing you did an EJ. I bought a 2007 Impreza NA with the EJ20 in it and i love that thing. Bought it as a family car daily with 180kkm on it. I´m so relieved to read all those comments here which say they run those for well over 300kkm with good maintanance and a bit of love. I so hope my one makes the 3 on the first digit in the future. planned to keep it till my kids go to school (wife is pregnant)
And thank you Scotty for the in depth look and well made explanation on how they work.
Very nice to see the guts of my motor! Love the content coming out of Scotty and the Haltech team. Great Aussie company!
Long-time Subaru driver here. Been bloody lucky in that I've never torn one down, so this was fascinating. Many Thanks!
On an EJ engine, when all the timing marks are lined up, it’s actually not TDC on Cyl 1. All 4 pistons are in the middle of their stroke. Also, on the LH head, you want to use a tool to hold the cams in position while you take off the belt so the valves don’t hit eachother.
Fell in love with Subaru circa 2002 when my coworker gave me the keys to his brand new WRX off the showroom floor for a weekend. Since then have owned several. Currently driving 99 GC widebody.
I just love the EJ
They make nice Power and when kept UEL they Sound so damn special. Almost like a poor mans Muscle car (im germany, so big engines are crazy expensive to run here)
I actually prevere the Ej257 over the 207 even when they are problematic.
Studs, haedgasket, downpipe+exhaust and a good Custom tune gives a relatively reliebale 350hp but with very good midrange torque wich is a blast to drive here in the alps.
That's actually why Subaru Japan keep producing the 257 overseas vs the 207. While still mountainous, Japan has significantly less average road height/elevation than US, Europe, which have higher altitude roads and steeper slopes.
@@impreza0109 While this is all true, a modern turbo will spool up quicker and stay spooled up for longer than what Subaru were working with in the 90s, and more boost means more torque. I drive a 2.5GL NA, but i've driven the 20 and 22 NA as well, as TLDR the 2.2 is the best. It's quick to rev high like the 2.0, but has power like the 2.5, it's really the perfect engine.

218,000 miles on my 05 sti. still pulls hard and sounds amazing. great video Tuning Fork!
I waited, and it was worth the wait. Thanks boys
Quite a few people requested it. Despite all its shortcoming, the good ole EJ seems to have quite the following!
My dad's 1983 Subaru GL wagon was purchased new in Louisiana, shipped to Germany, California, Italy, and then Texas, due to his US Air Force service. Over 200k miles on the manual, carborated, FWD station wagon, which 19 years later was still running and became transportation for a college kid for $1k. I now have a 2018 6MT Forester, getting 30 mpg in Cleveland Ohio.
I can't speak to the CVTs or the future of the company, but so far, I love my Forester and would buy another.
Gone thru 2 motors so far, 2 open decks and on my first closed deck now. I love these motors. I beat the crap out of it every time I drive it. Very fun cars to drive
Awesome vid 🤘I bought and still own a 04-05 n/a 5speed Impreza RS 2.5 new from the factory about 18years ago, having the scheduled maintenance done. Proud to say it still runs like clockwork 😉👍
I've got an EJ201 that's done 377xxxkms and is still going strong. Its an N/A SOHC non variable cam model so less to go wrong, the single cam allows for more porting of the heads for better flow so it has great low end torque for a 2L 4 banger. Helps that it's in an 1150kg 4wd GC8. I seriously reckon this thing will make it to half a million the way its running.
and it gets just under 7L/100km on country drives or 8.5-9L in terrible city traffic or when idling in winter at job sites in the morning to stay warm
Belt and pump on my old EJ204 was the first and only belt-job I ever done ;) Seem to worked out alright since its been running for years since.
The head gasket issues are due to the composite gaskets used only on the NA engines. Subaru bought a stock of several hundred thousand of them in the early 90s. But the composite head gaskets were NOT used on the FI engines as it was known it wouldn't hold up. Luckily, the differences between the heads and block are minor (so long as you stick with "like for like", so an EJ25 head on an EJ25 gasket on an EJ25 block+piston and conrods), so there's no problem putting an FI MLS gasket on an NA head and block. In fact, it's encouraged.
I salute you for the elegant presentation of your content and your classy eloquence.
Simply, "Gob Smacking" as I have rebuilt some early VW Beatle engines in the past, I never knew a Subaru was so advanced, Great video, Thank you.
Wow, eye opening. Cool engineering! Realize the engines flaws and plus points. Thanks Scott.
Thanks Scott! We appreciate you! 🙏
Lovely video Haltech.
I’ve replaced many head gaskets on NA ej’s in the past. Up until mid 2010, the factory was using a broken piece of rock in the fly cutter, you could feel the imperfections in the block decks. The OEM gasket pn 11044AA633 helped deal with this, and for some odd reason the factory swapped to MLS gaskets 6 months before introducing the FB25.
Cometic wants the surface's finish RA to be
I have a 98 2.5rs and I literally did my head gaskets in my garage with a piece of glass, multiple grits of sand paper, wd40, a lot of patience and counting passes, at the same time cleaned up and rebuilt the heads, I have now been driving it for 2 years daily with no issues. These things aren't hard to work on and they can be reliable if taken care of.
My EJ25 is the first engine I've ever done a timing belt one. Getting in there with everything in the way was incredibly fun! Quick tip tho, you can just remove your radiator fans/shroud and it gives you enough room to do the service without having to drain the coolant. Highly recommend having all of the specialty tools to do this job tho. Company 23 is a life saver!
Thanks Scotty I watch a lot of your work but I ve owned 3 Stis and 5 wrxs that my family drove..all tuned with bolt ons.no issues the way they were tuned and serviced..my fav was my version5 Sti...I've travelled all over Australia.. tracked my Stis even towed a ski boat absolutely no issues except the normal wearing parts and my version 7 had a fuel pump relay fail just love them still have my 2002 its immaculate
I can tell you do like Subaru.
They are wonderful cars and sound amazing. Hope to see more of your videos.
My dad has a 2008 EJ20 Impreza with 370k km on it, still runs like a charm, gonna have the engine and trans rebuild before it gets passed down to me though, can't wait
i really love EJ engines, i already have 2 of them, one EJ25D with a new short block, and one EJ204l original with 310000Km. still works as the first day
I've been waiting for this episode!
Thanks so much Scott
Love Subi's and you've dispelled some of the mysticism. 🤛💪👍
Tuned EJ257! 300,000mi on the odometer - ~150,000mi on the engine and transmission in my 05’ LegacyGT wagon.
She’s had some overheating issues (upper radiator hose getting to close to pulleys/fan blades, but she’s going strong!
17 psi of boost in sport and 27 in sport sharp with stock heads , open deck block with forged pistons and rods- beating on it on the Dragon , did autocross ( out of 43 cars had the best time , prepped Corvettes , stock miatas , automatic bmws , supercharged quattro audis , brand new M3) - and it has been 55K miles over the past 5 years. 5.0 V8s can not touch it. Grateful for this unique and reliable engine.
I use to own gtr but once I bought a wrx I fall in love ❤️ with it right away they are unique and sounds amazing thanks for the video it was amazing content ❤
I've got an 02 forester, EJ205 with bolt ons tuned to 186kw atw (18psi), it was 100kw atw when it was stock. Its been that way for 10 years and 70000 km and has been completely reliable.
Look after them and they are solid little engines, It would have been good to note how the cam cover seals, particularly on the drivers side are notorious for dripping oil onto the exhaust.
On point maintenance is everything on on EJ engine, consistently changing fluids particularly oil and coolant is the key.
Love my ej207 pushing a lazy 240kw atw on 22psi on 98 Street tune in my wagon but iv gone overkill on turbo setup n fuel system for e85 n more power love the torque and how smooth it is
I applaud whomever thought of adding the unequal header to this engine. That boxer sound never gets old
Not sure how I haven't come across this vid earlier love tuning fork! And I'll be on the phone by February for a tune from 450kms away !!
That was really cool. I don’t have the technical skills, tools or equipment to tackle such a project myself, but loved seeing it done.
I thought I’d had enough Subaru in my life and that fire was put out until 2:45.
Why you do dis Scotty!!!!
One of my all time favourites is the EZ30, great to dismantle! Similar to the EJ platform but with a few extra components and some differences such as variable valve lift and timing chain assembly. So much more but you get the point.
I saw those air quotes around "reliable." You didn't have to hit me in the heart like that.
Awesome seeing an EJ video from Haltech! You should do a video with upgrades and tuning tips for the EJ also.
They leak oil, make good power and they blow up lol.. and even so, we still love them. Why? They're super easy to work on, (except for replacing the spark plugs), and they're like Legos, mixing and matching parts from WRXs/Foresters/Outbacks & STi. I don't think any other car brand is easier to mix/match its parts. My very first Subie, an '01 Forester SF, I partially rebuilt its motor fixing the H/Gs with MLS ones, the motor never leaked again. Even since, I was hooked on working in these cars and did everything on it. Provided you take care of the EJs, and address the common issues like oil starvation with a better oil pick up tube, catch cans for the PCV system, the Cylinder 4 cooling, and not over boosting them, these are great all round cars that will last a long time and will be plenty of fun.
2002 SF5 Forester S/tb STi here, oil changes and belt changes done, running smooth as silk. Its a cracking motor, just a little thirsty.
I'd love to see a teardown on the VQ35DE! It's not the most popular motor but they have tons of potential and are probably one of the best V6 on the market
I enjoyed watching Scot do all the hard work!
Very informative video backed up with good explanations based on experience.
My stock power 2016 STi had headgasket failure at only 130,000km. Perfect maintenance aswell. 👌
I had a stock standard 2004 Subaru Impreza with an EJ20 motor in it. Absolutely most reliable car mechanically I’ve ever had
performance was good never lost a drop of oil after 10 years you could eat off the top of the motor it was so clean
I did service it and change oil every 5000 km because I’m fussy - I’ve done that with all my cars
they have a bit of an issue with liking upper cylinder clean because of carbon collecting due to the design or something like that
but absolutely reliable never overheated spot on cooling system for stock standard, absolutely reliable…..
Prior to that I had a 2 L honda Prelude the Subaru motor was better……..
The only component that ever had to be replaced outside servicing was a knock sensor, which threw up an engine light, and I drove that car for 15 years
Great work Scotty - you certainly know your stuff. Cheers mate.
My dad always told me there was a in-line six cylinder Ford in the cargo vans of the late 90s early 2000s that is absolutely bulletproof. Unfortunately I’m not a car guy so I don’t know the exact one but in the video you said if we want to see a tear down ask for it so that’s what I’m doing. Great video
I have an EJ25 in my 09 WRX, did the timing belt at 100k myself in my garage with the japanese Gates kit. Took some time but I removed the radiator to do it. I'm the second owner and afaik it's never been split, consumes zero oil. I do baby it though. It is my first subaru and I love the sounds.
i like manufacturers with unique engines - Porsche and Subaru, Mazda and its rotary- that smth that divert them from "mainstream" of industry
Good stuff Scott, been waiting for this one 😛 Plenty of EJ207's around after 2005 also, I have a 2009 GRB spec c with a 207, most of the factory backed race cars and S20x variants etc. were powered with the 207, pretty sure you can still buy a brand new 207 'crate motor' from STi in Japan
My current daily driver is a 05 Legacy Wagon with a turbo EJ and a 5-speed in it. I love it because it's fun and quick and yet gets 0 attention from law enforcement since it's a stock(ish) looking wagon. As far as I can figure, it's putting out about 300 American HP with the mods done to it. It's not the fastest thing I've driven, but it is a fun daily driver. I'm just glad to be keeping a 17 year old car on the road and out of the junkyard. It has a short list of stuff it needs, but I'm working on it. Thank you for the video. I always like to see differences in how people take things apart. I pick the method that works best for me.
I have a 2015 STi and this video really taught me a lot about the motor! Very Informative!
When I was living in England over ten years ago I went to a festival that had cars, a market and bands. I got to see the restored Colin McRae 555 car full noise around the track. Was one of the best things I’ve got to experience!
i imported a 96 legacy gtb, ive never enjoyed an engine sound so much. the ej20 is incredible.
Excellent presentation. I’ve watched quiet a number on UA-cam.
i love my ej motort but props to the transmision thats behind it i blew the rear housing bearing up at subie fest it still got me home 2hours and 45 minuts away 85 miles and drove for a week after till i put it on jack stands and fixed it
Great video Scott, happy you guys made this. Ive got a 09 forester xt stage 2, the ej255 is doing great at 176ks. 6month oil changes keeps her happy. The pcv system on these could be a whole other video and plays an important role in engine longevity.
I have over 150k miles on my 09, running a vf52. Unsure if headgaskets were ever done as I'm the second owner. Runs amazing with the Cobb AP and tune.
I just recently finished a rebuild (well, not me but for my GC8) and so far very happy with the current setup! It's an EJ20G closed deck block with a 2.5 crank and CP stroker pistons (so 2.14 displacement), built non-AVCS heads with 272 Kelford cams and all the Ferrea goodies to go with it 😬😬😬
Very responsive and very fun for the street but it is an old block so there's quite a bit of blow by and pressure in the case and heads.
All running with your Elite 1500 ECU of course 😉
