Speed Academy is the best no nonsense UA-cam channel. You guys are appreciated.
No nonsense? You must be a stickler for any fun 😂
Mighty Car Mods bud.
MCM and skid factory are also right up there for me, Alan is a wealth of knowledge. Also, I might be slightly bias supporting the local lads, haha
love it, great turbo choice, cant wait to finally see a well documented G-Series build on a EJ20 motor
ULH spool faster ? The killerB ELH helps spool turbo much quicker than stock headers did. Also gained more lbs/ft torque. Should've went with elh years ago :)
Nice build though
I caught that too 🤔. Pretty sure you and I are right the killer b ELH helps you spool faster than the UEL headers. Also why isn’t he running an adjustable fuel pressure regulator? I think you and I are a little late to the show seeing the video is a year old lol.
, yeah coming from somebody that's built a few fast Subarus they missed out on a ton of s*** to capitalize on this build but it still was pretty quality build
I do not see a bracket on the up-pipe to support it, you might end up with a crack in your up-pipe or header at some point due to that; the flange of the oem up-pipe is bolted to the passenger side head with two metal brackets(which you could cut up to weld onto the fullrace up-pipe), and the oem downpipe is bolted to the transmission to help support the turbo aswell
I’d plumb that wastegate dump pipe right back into the downpipe. Dave needs a quiet street car after all.
It is quiet until 14 psi or so. And it's not that loud.
Best Mod ever
Such an underrated channel, amazing job guys, really informative and well filmed.
Crazy how high quality this build is. I'd love to do something similar to my V5 Sti Coupe some day.
This build is coming together so well! Can't wait to see this on the Dyno (and hopefully on track too)!
I'm currently running a V9 Spec C 207 with pnp'd 20X heads, Kelford 220b cams, +1mm intake valves, beehive springs and Ti retainers spinning a twin-scroll 25G through OEM twin-scroll headers on my 2010 STi Special Edition. I start building boost around 2.5k RPM. I plan on making an atmospheric IWG setup here shortly using a Moore Performance twin-scroll downpipe flange.
I absolutely love this car, it's nice to see another 207 build in a GRB, but wish you had gone twin-scroll for better response.
Unequal is better for spool?! You learn something new everyday! I always thought the opposite! Nice video. Thank you.
That is assumption.
Real reason why is in some cases equal length manifolds add length to be equal. Shorter path with less bends, better spool (more often than not). Also material and it’s heat retention is a factor.
@@kenblackmotorsports5441
Thank you for the input!
Does heat wrapping the manifold also help with spool or is this a common myth?
Sick build! I hope in the end you give some cost estimates on the complete cost.
This reminded me that I need to get some header wrap, thanks guys. I look forward to seeing this car on the QEW
Great job! This Sti is gonna be an all-weather ripper!
Wow you guys wrapped that header way different than I did for my Legacy GT.
You LHD guys have it easy. So much room around the back of the turbo.
G25 on an EJ!!!!! This is the turbo that I’m putting on my Wrx 😁
Ohhh same. Which EJ do you have? And which G25 550 or 660? Rear housing? I got the 207 with Cosworth S2 cams, and the smaller v band rear housing.
hendrahendra ej 25 and the 550. Idk on housings yet, hoping to start buying parts next year. Going to run low boost on the stock block for a while
I just did a Perrin inlet tube on my 09 sti without removing the intake manifold and can attest to it being a huge pain.
That gasket will change the distance of the cam angle sensor to pick up point on the cam / gear . That why it has a o ring instead of a gasket. Hopefully it works
Yes! DP is a Hot Ones fan!
I can't wait to see how much jam this makes on the dyno. I hope you benchmark pump gas before going to E-85 or race gas. A similar setup with a DOM2.5 and Tomei EL header (no EWG), ETS TMIC, is making 383/377 on 93. I hope you make >400WHP.
Should have went equal length headers. Actually gives better low end spool up and is a healthier option for ej engines. Hence why the newer Subaru’s come with equal length from factory. I will agree that it will sound better unequal length. Awesome content regardless.
DOPE! I like how this project is going...I also make a "mean mugging" face when the music is playing for the abandoned STI
I'll gladly take that Tomei up-pipe if its not needed since i'm still running OE turbo lol ;)
Build is coming along awesome! Can't wait to see how much this EJ makes!
projektd I have a GT spec uppipe if you’re interested. It is also a 3 bolt flange exactly like tomei.
@@JAM4382 wow awesome, thanks for the heads up. What are you looking to get?
projektd $125 sound fair? It’s brand new. I’m on my second manifold as the first one cracked so I have a spare uppipe. Do you have a manifold that uses the 3- bolt flange for the uppipe?
@@JAM4382 im still on my OE one, so im not entirely sure about the fitment. Thanks!
projektd no it won’t work. You need a 2-bolt flange uppipe to fit the stock manifold.
i cant wait to do my build you guys are the bomb. keep up the good work.
Why not ceramic coating on the header?
Confused how did you hook up the two bolt up-pipe to the 3 bolt header? Do the two bolt holes match up to two of the three when in the correct positions? That’s what’s stoppped me from going rotated. My header is 3 bolt. Or did you just bolt them together to get close fitment for everything
Dang I'm interested to see how this turbo does!! Grwat work guys! This sti build is sick!
It will do 500+ hp on good fuel, it will come to full power below 4K, not sure what else you want to see.
@@dj4monie salty??
The Tomei header is nice.... I know. I'm on my third one.
Do you still keep some nice subie rumble with those bro?
Smashed it ten times! Can't wait for the next one
You guys should have gotten the rotated kit from BNM Performance Fab. He builds rotated kits for anything and from stock style 2 bolt and 3 bolts uppipes
outstanding job
With that setup I would be able to run the aftermarket top mount I have sweet
Looking forward for the results with the G25 turbo and different housings.
Not sure why, you looking to say "It's not a EFR"? .72 will make less top end power but it won't be that dramatic compared to the .92 it won't make max power which on a AWD car and that turbo would be about 550 hp without using the bigger one.
I'm not looking into max power, but boost threshold and power band with both housings.
this build has me stoked for a subaru, thats a first
Sheesh I wish I could afford a nice 207 swap. Can’t wait to see this thing rip!
I was always curious why there was never a big use of heat shielding/air barrier for the exhaust-oil pan clearance. I would assume why these engines like to fail is due to the oil temps from the headers.
Turbo sits right by cylinder 3, and the extra heat soak there can actually cause failure in that cylinder. I have seen people rectify this by adding heat shielding and using aftermarket engine management to send extra fuel to just that cylinder.
Could you guys talk about Pete's old integra? Seems like a car many people could relate to and learn from you guys
Nice Video guys!
But I think the downpipe setup is not the right one for daily driving. No Kat ect
Another great video guys. When's the Miata build coming keep seeing it in the background? lol
If i abandon my sti next to your garage door can i pick up after you guys build a beast for me. 😆 🤣
This STI is going to be a monster
Is the cylinder 3 oil blank the same thread as the location under the alternator
uh, love'n the content but where's Ken and his RX7?
Rodolfo Diaz i been saying we need Ken wagan
We need his 240z build.
The last dab T is fire ;)
Thanks for not using that "midnight hour, whiskey sour" song. 🤘

"Me and Nam"?? Come on dude! Represent that Canadian education properly! It is "Nam and I". 😋
Don't forget elbow's off the table you victorian nazi!!
Nam is born after the Vietnam war :)

Why would you put the wrap over the stainless header?
Just a tip guys for when your heat wrapping headers. Never use those stainless steel zip ties as the harmonics and vibrations of the engine actually loosen them up over time. There is a proper tool to pull them ties super tight but they can still work themselves loose. Obviously it comes down to how hard the car is driven, how long they have been on the car etc. I have found that the best thing to use is actually normal hose clamps
Normal hose clamps suck just as bad. Install stainless steel wire with a lockwire plier. Much tighter and much cleaner looking any type of clamps or ties out there.
Use safty wire
Why didnt you guys go with a rotated mount, instead of messing around with trying to get clearance under the intake mani?
I would forgo wrapping the header in your climate.
So this Tomei USA and OG Tomei japan are two separated companies now, i assuming they are not aware of it.
Is Dave wearing a First We Feast shirt?
It should be who works in the car the most that get to daily drive the car
PERFECT JOB
I know this video is 2 years old but DO NOT run a light weight harmonic balancer. If anything you want a better heavy ATI or other race options. Light weight give you Maybe 1-2hp but allow more engine noise and will cause extensive wear on your main bearings.
Nice vid! I haven't watched it yet but I know it will be. Keep it up guys
Hmmm. Nice products but that exhaust systems needs some flex somewhere.
The intro is epic
Nice Hot Ones shirt Dave!
Can I have this car, I daily a 08 Wrx Hatch, it’s be nice to have an STI to romp on for the weekends
PT is in the Daredevil season 3
Why didn't you just do the v band on the tomei up pipe?
FYI you'll get MUCH better spool with an EQUAL length header, NOT an UNEQUAL length header. This is coming from a guy who works with high horsepower subarus everyday, and owns a 700whp wrx, ive played with so many different types of manifolds and equal length by far grants better spool, and much more torque. You can call a bunch of the leading subaru tuners like IAG performance, Prime motoring, outfront motorsports, rallispec, killer b, and every single one will say equal length headers are FAR superior than unequal length.
this^
Do elh sound gopd bro?
@@alexortega714 depends on the type of elh, like who makes it (some have different collector styles, some are made from different types of steel, some have bigger/smaller inside diameters), also depends on other mods like if you have stock cams, aftermarket cams, avcs or non avcs, different turbo, different exhausts (amount of mufflers and material of the metal plays role)
too many different factors to flat out say if they sound good or not, ive heard some that sound good, and some that sound terrible
Did you also include the fuel rail, or just the lines?
oooff. shoulda went EL.
Pls do another swift boys? M16a engine mayb a cheap fwd race car
Why not just cut the flange off the Tomei pipe and weld on a v-band flange?
Unequal is better for spool ?????
I'd like to do something like this (and learn from the experience) but have no idea of the cost.
How much did this all cost at the end?
miata in the back?!
Finally the fun making parts lol
Why the heck you wrapped exhaust manifold, rather than cover it with ceramic coating? It's 2019 outside...
wrap is cheaper but effective, coatings look nicer, keep innovating but cost more.
Should have just went with a full race manifold as well... I believe they use 321. Which you woulnd't have to wrap.
They didnt have any in stock and I get what youre saying about the metal but its still way better to wrap it for heat suppression as opposed to leaving any manifold bare.
Thank God they went unequal length; so, it won't sound like a like a kazoo.
304 stainless? I think that’s food grade stainless.
All them nice shiny parts are nice and all. But do they rust brah!!!??? 😅
Most shiny things are coated I think
I say the .9 makes more and out spools the .7 exhaust housing
Not by what I have seen thus far. Not much difference in spool to either the larger housing will flow more assuming you don't have other problems preventing max power.
Hey guys
What type of sensors are these. Aftermarket one or came from ej207 engine
You should really try an EFR7163 on there, the G25 lags it in both response and top end. The lighter exhaust wheel also means the boost threshold in lower gears is better.
Based on what? Have you tested this or just heysay?
@@dj4monie I have an SR20 with it running about 24psi on E85. Compared to my old GTX3071 it is a big difference especially with lag but also improved top end. It was pretty apparent but I also verified with virtual dyno while road tuning to compare the difference.
Will this fit on a 2018 WRX STI?
This video sponsored by Turn 14 and Nam's wife and kids. Maybe Nam should be in the competition to get the car as a daily driver too.
What about the touareg dude ??????????????
More vids are coming
Cobb commercial?
Whats the original Name of the Subaru WRX STI Turbo Type ?
Equal length headers are also better for even exhaust temps at all cylinders which technically should increase engine life over the unequal length.
Hmm... looks like a Tomei USA header instead of a Tomei Japan header.
Last Dab shirt makes me think you guys might be hot sauce fans? If so, any you guys would recommend from your area? Cheers from TX.
Almost a little sad to wrap such a beautiful piece. ;-)
Plenty of people don't bother with wraps or coatings. The entire turbo system will perform much better wrapped and coated.
@@dj4monie - yea, I am well aware. The benefits from keeping the heat inside the pipes instead of radiating all over the place are worth it. I also get that this is a daily, and not a showcar. That's why I said "almost" sad to wrap it.
Water cool it!
Why not use JDM ECU? Smog compliance? Side note: in my side of the world the GRB STI normally comes with EJ207.
Why bother and jump to AEM Infinity or Haltech 25000 Platinum.
Nice!!
moist.
I picked up a Tomei UEL header for my 2009 STi and Im having a bitch of a time installing it. I cant get the slip joints to move so I can adjust it to the proper width. Did you guys run in to the same issue?
No
Boys can you whack a new heat shield under the bonnet, that buggered one is gunna do my head in..............
I’ll still wax it with my e55, should’ve went with a 6266 and run low boost
It’s not a drag car but if you’d like to come out and try to beat it at our track let us know! 😊
Speed Academy I got a c6 z06 for that 👍🏻 so pick ur poison lol we have it figured out in New York😂🔥
@@elevatedperformance Bring the C6! You're not that far from our Track. Would make for a great video.
Speed Academy I’m gonna be in New York safety track this fall 👍🏻 but my e55 is rdy for Atco any day lol
Is EX-Preme just a mix of extreme and supreme?
Yes lol
Fully built motor? Did I miss that part of the build?
Pretty sure they built the motor before they started this series or even found the car
there’s a serie of video on that!
I really want some chicken wings now
Anyone know how Speed Academy keeps their shop/business afloat? Looks like they are mechanics who own the shop and make videos as a side hustle? I'd love to have them work on my car.
This is our full time gig. We dont work on other cars just our own. Sponsors and UA-cam revenue plus patreon keep us afloat.
