Default T3/T4 turbo's

Does anyone run any of these on there cars? I was given one by my little brother who got a bigger one for his S10 extreme. I know the flanges are different but does anyone know how much pressure these put out?

They are not uncommon at all. Its a pretty good type of turbo to use on stock ej25 motors if your gonna turbocharge, that is depending on the wastegate setting. However my guess is its probably above 8 psi output and you wouldnt want to use that on the stock bottom end. Chances are that using that turbo, especially with the different flange would be more trouble than its worth. Custom fabbed pipes would be needed and you still might have problems with boost pressure.

Ok thanks for the input. I know about the pipes, i can fab those on my spare time, but good point about the bottom end. I am gonna use my pfd on a wrx or sti motor, used out of a boneyard in central Wa. Know the guys well and they'll even deliver it, to my dads house. Any comments on running a T3/T4 on a wrx or sti with customs pipes guys??? the boost pressure issue might not be worth it alone...any input would be awesome. THanks

Certain T3/T4 turbos can run upwards of 20 psi. I doubt yours is one set that high, but your definately gonna need a better bottom end.

rivaman,
Are you looking at putting this on your '95? Is it still an Ej18 in there? If so, you are being misdirected. We've been hammering on the Ej18's with stupid amounts of boost for most of the last decade. They are bulletproof. Their greatest obvious weakness is their compression ratio.

One historical solution for that has been to run water injection. These days you can also go to E85 for a little better knock resistance. You can run 10-12 psi on a t3/t4 without too much risk as long as you give it enough gas. Just intercool it and give it gas.

Do a search for TurboL and Subachad and their builds. You'll get some ideas of what you can do with them. And the beauty is if you pop it, new ones are $100 or less at the local junkyard all day long.

I've got a buddy doing a build on one right now. He's putting Ej205 heads on it and running it with a Hydra. Should see about a 1bar of boost on a daily basis and closer to 1.5 when he takes it to the strip to play with it. And that brings up another point. The EJ22 heads have a marginally larger combustion chamber. If you swap in those for your EJ18 heads, you'll drop your compression ratio down under 9:1 and make it more boost friendly.

Feel free to drop me a line if you want more informed and experienced advice.

please, ive been looking for someone willing to help me out and give me advice. yeah i have the ej22 heads on since i blew up the ej22 shortly after buying the car. I know that the t3/t4 can run high boost...look at hondas, they seem to sport the t3/t4 as daily attire. not to knock any honda owners, i love the durability of the 86 hatch back my parents had. The bottom end i know has to be beefed up. Matt, if ur willing would you please explain the set up to me, and i will look at the builds you told me to research. The one thing is i'm wondering about is engine management. Thanks for those who helped me.

Gabe

On an '95, which uses a somewhat ancient ECU the best solution is something like the Emanage. However I've been hearing good things about AEM's new piggyback ECU, but that's going to cost more money since you can find used Emanage's all over here and on on Ebay.

I just assumed that you had an Ej18 in there since all the '95's I've ever owned have been that engine. But since you already blowed it up, as long as your heads are good, you want to find an Ej18 bottom end. Don't worry about beefing it up. It's a good bottom end for what you want to do. Or if you come across an Ej20g bottom end for cheap that's a good option.

Let me get back to you with more. I know a guy up there in AK who may be able to help you find some stuff. I've just got to remember his screenname. I'll post it up later today for you.

Artic Assassin. He's a dealer tech in Anchorage. He's got access to all kinds of goodies you don't easily find in the AK junkyards. PM him and tell him I sent you...

Thanks Matt, I re-searched for builds last night, I didnt find TurboL's build but I found a 93 wagon build that used an EJ18t. It helped me understand a bit more. At this point what i need for my list are: up/down pipes moded for t3/t4 flanges, and intercooler, an aquamist, bov, and an ems. Thank you soo much for the help. I will contact Arctic, I think ive seen him in the AKIC forum btu not sure. Thanks again, Im going to give this a try.

Shoot me a PM from time to time as you do the build and update your thread. I'll pop in and give you input.

it will be lagggy with a 1.8L.

raising the rev limiter helps alot..Innovative tuning pushed 40 psi through a ej22t long block, autotronic ECU, gt35r with racegas/meth and ran like an 11.1. he was spinning it to around 7K i think..

it blew on a 40 psi spike tho..lol

wow, that's a lotta boost. I was wondering, Red- are you running a special block now?? I read your intire thread, impressive as hell. I was thinking about re-building the 2.2 i have in the shop to use for the turbo motor. I was swayed since people say that P1 motors have head gasket issues. I would like to use the 2.2 tho for the extra displacement. Since PFD's came today, I ordered Helix catless up and down pipes. Looking for an ebay FMIC or TMIC. I know i still need EMS, BOV, turbo back. Any suggestions, Im getting all my parts in line before I try this so I'm not waiting and waiting to complete this build. I can do it on either motor, so it doesnt really matter to me. But one question, I cant figure out where the down pipe outlet is on this damn thing, its obvious as to where the up pipe bolts, but not the down. It might be just because Im working 13 hrs days, and get 5 hrs a sleep a night mon-fri. Just wondering if I am over thinking this or am i going blind. Any one with a honda that can send me pics? thanks much guys

Post pictures of your turbo.

Unless it's flanged specifically for a Subaru, those pipes you just bought won't bolt up. Also, to run them you will want to acquire a turbo crossmember and replace yours. They won't clear the stock NA crossmember without hitting.

It's worthwhile to buy the right turbo and not dick with fabbing pipes and hoping for the best. Especially since turbos are cheap if you look hard.

Exactly what "T3/T4" do you have? This the same for a T3 or a T4 turbo. They are Garrett make for the 200-550HP range. Depending on the exhaust wheel/ snail and the compressor wheel/ snail will tell you if this is a good turbo.

I sent the t3/t4 to a friend with a honda. looking for a td04 now or anyother small stock turbo. i dont plan on running more than 15 psi. thanks for the input guys, i tried to think about how to do it with what i had and no flippin clue at the end of the day. Thanks for the encouragement to do the build on the ej18 tho.

rivman,
I've got a vf11 off of an ej22t engine. I'll ship it to you for basically just the freight. They aren't really worth anything. It's a good training wheel turbo. The only problem with it is that the compressor outlet is clocked at kind of a weird angle to use an intercooler since it comes from a non-intercooled car.

Just an update. I think im gonna build the 2.2 now. My birthday was a lil over two weeks ago. My brother sourced me some 2.5 DOHC heads to use on the 2.2. Any advice on which the DOHC heads should go on?? thinking about turbo cams for em from Cobb, or Delta regrinds. let me know guys, im getting excited since Im getting a stock wrx complete turbo exhaust for 100. Matt ill take that VF11 off ur hands for whatever you want. THanks,

Gabe
