The de-stroked EJ engine sounds incredible and screams north of 10,000rpm with ease, boosted by a Garrett GTW3884 turbo that peaks at around 40psi and holds a flat power curve from 6000rpm onwards.
What is a de-stroker? I would assume your replacing con rods for smaller/shorter ones? Does this need a larger crank? Wouldn't there need to be a huge valve/spring/cam upgrade too? Does this significantly reduce capacity from 2ltr? Can't believe the 5speed is lasting either. I modded my old 05 wrx to about 200kw atw and it lasted barely 3 months on the stock 5speed, destroyed the gearbox on a launch too not a dodgy shift like some. Either way, subie gearboxes are weak as piss and so are their diffs. The rear diff went before the gearbox actually lol. Next time.... EVO
Tyronie balonie De-stroker is a shorter stroke crank. I dont know the details on this engine, but to make that RPM, i would assume a shorter stroke version of EJ20. Maybe a 71mm crank or thereabohts??? My particular engine uses an EJ25 block. (With CDB, pinned mains, 14mm studs, up rated case bolts etc etc etc to keep it together haha.) My de-stroke is done by using a 75mm stroke billet crank (EJ20 crank) instead of the regular 79mm stroke EJ25 crank. Because it has a 4mm shorter stroke crank, i have to use custom length con rods which are +2mm longer than regular. This is so the piston hieght remains as it was at TDC. The net result of a de-stroked EJ25 like this is usually around 2.35L of displacemnt. So you do lose some displacemnt. But not a great deal. You end up with around the same displacment as a stroker EJ22. But you have a more rev happy engine. Also, your static compression ratio will reduce. But this can easily be overcome by changing pistons to ones smaller dish volume. My pistons are rated at nearly 10:1 comp ratio for a standard EJ25. With the de-stroke this will reduce somewhat. Im hoping to be somewhere around 9.5:1. Why would anyone want to de-stroke an engine??? Well, RPMs. A shorter stroke crank has less distance to travel per engine cycle. This means its piston acceleration/velocity isnt as extreme as it is in a larger stroke for a given RPM. This means you can go higher RPMs than otherwise possible with a longer stoke. Another thing that helps with the RPMs with a de-stroke is rod to stroke ratio. The higher this ratio, generally the better the engine is at higher RPMs. (Sports bikes and F1 cars have really high rod to stroke ratios usually somewhere between 2:1 / 3:1, and we know how those things love to rev) So by using a longer rod and a shorter stroke, you are altering the rod to stroke ratio. From memory, a typical EJ25 is somewhere around 1.6:1, a de-stroker is somewhere around 1.75:1. But as a general rule, the higher the ratio, the better for revving. The higher rod/stroke ratio effects piston dwell at TDC/BDC. Which basically has a positive effect on volumetric effieciency at high RPMs. It also keeps a straighter con rod angle during the stroke. This gives less side loading on the bore, and less friction. In order to make my engine want to rev, im using very large lift and long duration cams (282°). Im doing an AVCS delete. (Dont need heavy cumbersome AVCS pulleys at high RPMs.) Im doing oversize valves, with enlarged valve seat internal diameter, and extensive head porting. Im using beehive valve springs and titanium retainers because they are lighter than dual springs. And are rated for 9.5k rpms and will handle the boost levels i want to run. And im also using a billet crank, which is lighter. And also has straight line con rod oil galleries drilled in it and also oils each con rod journal from 2 main journals. This is an advantage at higher RPMs when compared to a typical EJ25 crank which has #2 and #3 con rod journals oiling shared from a single main journal. And also has a complex internal oil gallery routing which can hinder oil supply at high speeds.
Thank you for such a detailed reply. I appreciate your time and effort too and you covered all and any questions I would have about why it is done this way. You went above and beyond good sir
Hahaha fair enough. I just always wanted to build an NA EJ22 or EJ18 even with some cams to run like 9k RPM just for fun. Probs never will though even when I get into building engines. :P
De-stroking lowers maximum piston speed for any given rpm, lightweight parts and scrupulous balancing keeps the harmonics in check(although a flat-4 is an inherently balanced engine anyways)....the biggest challenge was probably oiling and valve train control. Thumbs up here, and I'm not even a Subaru fan! Something different and a bit insane all in one.
destroking do not reduce speed automatically. You need to work at the same max rpm limit to say that. You mean piston acceleration for the same rpm ? because linear speed can be the same,or even greater,even destroked seen this engine rotate twice as fast as original.
michaelovitch The piston speed goes down with a smaller stroke . For a given crank rotation the piston has to travel a smaller distance . Pretty basic stuff .
Only if you keep the same max rpm.... Here it went from 8300 to 11500,so you can't tell if the speed went down unless you know the previous and actual stroke too. The point was to keep it as similar linear speed as possible to be able to rev it this high. To be reliable i guess. You have to take all parameters in consideration to be able to say that destroking, HERE, reduced the piston speed. Pretty basic stuff only a moron can understand ? or no ?
michaelovitch ' For a given crank rotation'- I don't think I can use simpler english than that , never said anything about two different engine speeds and comparing piston speed . If somebody wants to rev higher they destroke to keep piston speed in check simple. That was what the OP was trying to say.
On the track, that was such a great sound... Music to my ears. You can almost feel that surge when the gear changes and turbos start spooling up, along with that glorious noise... Ahhhh
pokinacha - mostly what it's going to do is drop a valve through a piston... This is the sort of time you want pneumatic valve gear, like an F1 engine.... They say there's no substitute for cubes. In some ways, that's true, but in some, it's not... Very short stroke, very high revs, lots of boost, formula one history shows you can make over a thousand hp per litre doing this, at least in a qualifying engine... In 1986 qualifying engines were producing 1,300 ~ 1,600 hp, at least for a couple of laps. An F1 car on the front straight could go over the start/finish line at 180+ mph, just changing into top gear, and it would still be wheel-spinning over bumps. That's with a 625kg car and over 2 tons of downforce... Longevity is another story, but.... Race engines made about 800, and they lasted one race & no more.
Kneedragon1962 100%. The other option is rotary valves which are banned from F1. The 80s turbo cars were incredible. The BMW M10 and Renault EF1 both sub 1600ccs and making over 900bhp in qualifying trim despite the melted compressor wheels. My favourite all time response to the 'no replacement for displacement' argument is the BRM V16 from 1947. 1500cc V16 with a supercharger pushing upwards of 5 bar(72psi) for 600bhp at 12000rpm and the greatest engine notes of all time. Notable mention to the Alfa Romeo 155 DTM Tiv6 which was 2.5ltrs, NA, 420bhp @ 11000rpm
but thats not a response to the argument at all. Anyone who argues against that point doesnt understand it to begin with. No one is saying that you cant make power with a small displacement. In fact what is small and what is big is entirely subjective anyway. The argument is when you go smaller there is always a compromise somewhere. turbo-its lag, heat, complexity, etc. Super charger, complexity, belts, heat etc, nitrous- complexity, bottle size, limits, tuning considerations, etc. Always compromise and always a cost. Therefore there is not a replacement for displacement just different means to an end with their own unique compromises and problems.
No kidding and being a base Impreza L with this beast of an engine init 🤣🤙🏽 who woulda thunk that a boxer could rev that high and sound good whilst doing so
WISH WE COULD GET AN UPDATE ON THIS BUILD !!! THERES A COUPLE WAYS TO GO ABOUT DESTROKERS..HOW LONG DID THIS BLOCK LAST ? WAS IT OEM BLOCK WITH UPGRADED FASTENERS ? WHICH BLOCK, CRANK , PISTON TO ROD RATIO ? COMPRESSION? SO MANY QUESTIONS !!!
Well if I was doing a high RPM NA build I wouldn't destroke. It would be stiffer springs and different cams with some porting and polishing etc. I get what you are saying though.
Willy D Any compression ratio change from de-stroking is of absolutely no importance or consequence on a build as complicated as one revving to 12k, NA or forced. You could not use the original pistons or rods and expect it to not tear itself apart. You would have to use custom pistons and custom length rods to correct geometry, reduce wieght amd increase strength. So you would specify the dish of the piston to give you your desired compression ratio taking into account any other variables like stroke.
Nothing wrong with dropping the torque and getting the power back with rpm, so long as the oiling system is proper and the engine management is top notch.
underdrive pulley set up would make fix that. they probably spin at the normal rate of speed when he gets north of 10k. less drag anyway good for racing when engine speeds are going to be constantly high.
Beastly! Mine only makes 470, but I only have the boost set at 29 psi right now, I don't think I'd ever push it that far even though it's built to take it.
This is into 80's era F1 turbo territory, in the boost and rpm departments at least. Turbo era F1 cars made more overall power, but to turn this speed takes some know how. Did I miss the footage of a tach showing 12,000 rpm?

Betty and the GT3 RS are my inspiration for my EJ25 going to be 300hp 10k rpm with the stock auto transmission (I’ve seen plenty of builds with it and i know she’s strong enough) one day I’ll have something as nice as Betty amazing car
that is absolutely the coolest fucking engine I've seen in a long time, seriously the only thing that is even close to that is a 20b I saw with twin turbos and a supercharger!!
It's always been a dream of mine to get a ej over 10k as NO ONE had done it...i still wana do it NA, but I'm excited and happy that I'm not the only one.
It can last a while seeing it's most usable powerband is at 6000 rpm to 10,500. Anything below wouldn't stress the engine much especially with longer gearing. It could work as a daily.
Fun Fact: The Subaru doesn't get it sound from the motor design, the sound is from the uneven header length to the cat-back which causes pulses in the exhaust system which gives you that iconic sound. This is why new subarus, porches and even the new gt86 sound nothing like the old wrx's. The exhaust setup is different.
Uneven length headers give it the subaru sound, but even length headers are better for performance because the exhaust gas flow is less turbulent. In a UEL design, the exhaust pulses collide at the Y intersection, while in an EL header they alternate, giving less turbulent flow. Subaru used UEL headers to save space in the engine bay, but nowadays they fit EL headers. The difference is usually negligible, but at very high RPMs the pressure pulses caused by UEL headers can be a problem. The car in the video sounds like a V4 because essentially, it is just a V4 with a 180 degree bank angle.
He just did as a Sly comment lol gtw are not the best turbos Lets just say Koval evo ran one an went 9.5 @ 150mph+ with 650whp with same turbo ;) All Weight an not an Auto ;) This is even less weight then a Tme evo
Wright Marshall are you serious dude? You lose torque but torque carries further throughout the powerband and on boosted apps you typically can gain power seeing you increase VE by allowing the piston to dwell longer at TDC.
Sarkin Makanda also the fact the power band is flat after 6k means it's running out of air from the turbo. I would love to see what the head work looks like on this thing. Has to have some massive intake runners.
lol great sleeper imagine you take someone for a ride and through 4-6k rpm it's not that fast and they aren't impressed but then the real boost comes in
I have always wondered if anyone had tried destroking these. V8s been doing it for years but never heard anything on boxers and very little on imports in general...

Absolute beast. Nice to see some Aus content on UA-cam, it’s normally flooded with American crap.
I knew this was Australia cause it said "Ladbrokes" on the ads
I want one of these engines in my 86
Been thinking about a build like this for quite some time. Be interesting to see how it develops.
badass sleeper
Please please please replicate this build with the eg3.3
11,000rpm and 42psi only 600hp?? should've put a barra in it
in b4 "a K20 would make that power at 20psi and 2/3rds the rpm" whoops too late
He just did as a Sly comment lol
gtw are not the best turbos
Lets just say Koval evo ran one an went 9.5 @ 150mph+ with 650whp with same turbo ;) All Weight an not an Auto ;) This is even less weight then a Tme evo
That's what happens when you destroke. You lose torque which means you also lose power
Wright Marshall are you serious dude? You lose torque but torque carries further throughout the powerband and on boosted apps you typically can gain power seeing you increase VE by allowing the piston to dwell longer at TDC.
Sarkin Makanda also the fact the power band is flat after 6k means it's running out of air from the turbo. I would love to see what the head work looks like on this thing. Has to have some massive intake runners.
I wonder how they got around that weak centre bearing that EJ's love to spin?
Machine the crank and use a phase 2 block with a 5th journal bearing. Could possibly even run both
Why didnt you actually show the dyno chart
Watching how slow that tach is climbing at 1:00 makes me doubtful of 600whp
Strap Betty down!!!! Damn she's mean
It actually sounds good, unlike most subarus with a flat 4..
lol great sleeper imagine you take someone for a ride and through 4-6k rpm it's not that fast and they aren't impressed but then the real boost comes in
At least this can rev higher than Takumi‘s 86
I want those revs please for my brz! 1:12 just track pads? how does the car survive even one lap? 600hp, but only like 350tq or something, right?
Sounds great
I have always wondered if anyone had tried destroking these. V8s been doing it for years but never heard anything on boxers and very little on imports in general...
i love it sound
How good is the sound.
You all would make so much money here in America
What was it destroked to exactly? I must’ve missed that part.
Shoter the stroke or de-stroke to make the rpm higher and achieve higher horses as the horsepower calculation torque x rpm = hp .Right?
Just Nobody lmaooo. Torque x rpm.... 300 torque at 7000rpm. 300x7000= 21,000hp. Yea seems correct.
Chris Moltisanti the true calculation is "(torque X RPM) ÷ 5252 = Horsepower . Try it
Alex McGraw i knew that, i juz try to say it simple way. Thanks
right wing conservative stunt bums 77 wow 😂😂😂
That boost though
This comes as a bit of a shock to me. I always thought the whole point of a boxer was low end power. 12 grand is mental. That's F1 territory
MADNESS!!!!
take my money
Love high revving engines, my GSXR 750 tops out at 15000rpm. A car @ 12000, yes please. :)
"The theory of this car is to think outside of the square" did you purposely avoid that pun?
Same, gives me ticks.
If they removed that filter I cannot even imagine the gains. RIP.
