Turbo Charge EJ22?

[CuevaCustoms]

How do I turbo charge my EJ22 from my 93 Legacy?

[1-3-2-4]

simple and safe way engine swap.

[CuevaCustoms]

theres no way I can turbo charge the stock motor that it has? What motor would make a good swap?

[1-3-2-4]

you could turbo charge the motor with a kit but it would not be as reliable as a factory turbo charged motor. Good motors are EJ22T, EJ20

[CuevaCustoms]

where could i find a kit for the car? ARe you talking about an EJ22t from a legacy or an impreza?

[Huffer]

search for AVO turbo kit, I do know RS25.com has at least one turbo kit for sale.

Because you're running a 93, you could probably find a front clip from a 90-94 turbo, and swap that in. You'd be boosting an iron block, which would be pretty tough if prepped right.

www.usmb.net has some good info.

thanks for the help. Can you do me a favor and tell me all i would need to turbo charge my car other that the kit? can you point me in the right direction to find a front clip?

If you are wanting to engine swap you would need (at minimum
-working turbo motor (obviously) - Legacy EJ22T, WRX EJ20 or EJ25
the motor needs to have: turbo, intercooler, injectors, etc
-the ECU that goes with the motor
-a front crossmember from a turbo Impreza/Legacy (so the downpipe can clear the frame)
-an exhaust for a turbo Impreza/Legacy (stock WRX is fine)
-the ability to splice wires for the interior/exterior lights, washer fluid, and all other parts not essential to the actual running of the engine
-upgraded fuel pump

That's all I can think of off the top of my head but there's probably more. Here is a good place to get your questions answered:

i say get build a kit, could be done for well under a grand imo, and get a rising rate FPR and keep the boost low. if you pop the motor they are a dime a dozen and cheap to pick up.

[CuevaCustoms]

I would rather get a kit but i cant seem to find any. Whats FPR?

it's a Fuel Pressure Regulator.

[StatGSR]

there isnt going to be any kits for a 93 legacy, you gota look for 2.5 RS kits, and even those will likely have to be modified.

all you need to turbo it is an custom up pipe, turbo, down pipe, intercooler and piping and BOV, an oil sandwich plate, oil return bung in your oil pan, and some oil lines.

[CuevaCustoms]

has anyone turbo chargered this motor yet?
how hard is it to install a turbo?

[StatGSR]

yes that motor has been turbocharged many times. and the later depends on your skills and understanding of turboing a car.

[CuevaCustoms]

im kinda new at it as you can probably tell. Right now I have a EJ20TT sitting in the car (not full connected yet). I need to still get the 2nd turbo to fit right. I figured a way to do it. I just dont know if its worth me to do that or just put the old motor back in it a TC it. The other problem i have with the TT is the wiring. I know someone that said they can do it. But I don't know if its worth do that.

[WinterKnoll]

I would stick with the EJ20TT that's in there now and just figure out the wiring situation. I don't think you'll get as much performance from a bolt-on turbo.

I'd be interested to know how you got that 2nd turbo to fit. The twin turbo EJ motor only works with RHD from what I've been able to tell.

[Bohemian_Funk]

Well I don't happen to have the luxury of a turbocharged motor at the moment, but from what I've read, it'd make more sense to keep the EJ20R/H (guessing) that you have, and just convert it to single turbo. If you really want it to be a 2.2L, then... err... swap the crankshaft/con rods I guess? I really honestly wouldn't know, but considering the EJ20H (the lower HP of two evils ) from the JDM Legacy GT had roughly 245hp STOCK (note: on much higher octane fuel, mind you), I would easily choose that over my N/A 135hp 2.2L engine any day of the week, slightly better extreme low end characteristics or no.

It's a matter of fabbing up custom pipes for the turbo. the reason the EJ20TT engine doesn't fit normally is because of the downpipe hitting the steering column.

That must be the reason why ebay has a crap load of EJ20TT's on ebay some say it's not worth the hassle anyways.

Bingo! Single turbo conversion might not be too hard though..... not sure, I've never really even considered the TT motor as an option for me.

yeah it looks temping but I'm sure you could find a Wrx engine for about the same price.

LOL yeah seems like they all have a transmission attached huh? I saw one yesterday without one.. I know some on NABISCO was saying the brake stuff was in the way it seems each anwser is not the same.. But from what I hear a single turbo was better then the Twin Turbo version.

[decke48]

the problem with the TT is the primary turbos was badly tuned and the manifold didnt provide good spool. but with a manifold and a good tune there a blast to drive.. much more fun to drive than the single turbos

[Bohemian_Funk]

I'd bet with proper tuning and replacing the parts the stock turbos would probably allow you to hit the 300hp mark with pump gas... but I'm by no means an expert

[CuevaCustoms]

i think you guys convinced me to stick with my original plan of doing the TT. I got kinda of discourage just cause of all the work that its gonna take. Thanks for all the help. MY leg should be a mean machine when its finally done!

[Bohemian_Funk]

No problem ! If later you want to run higher boost, but don't want to try and go the route of a closed deck block (i.e. - REALLY F'ING EXPENSIVE, comparatively), you might take a look at this thread on the NASIOC forum: http://forums.nasioc.com/forums/showthr ... hlight=DIY

The honda/domestic/muscle guys have been doing this for basically decades (at least the muscle guys), so you know that it at least works to some extent.

[Plays_with_Toys]

Ummm... Your car is a 93. Which means it's OBDI. Isn't that like the easiest motor swap subaru's can have? That's why a 1995 shell bd/bk is the perfect swap if you want the new body style.

I would definitely start getting frisky with doctor google and find out the wiring on your motor as it should only be a few wires that you need to splice. (compared to the many many many it takes to wire a new one).

You also aren't doing a 6 speed swap (I imagine) so that's even less to worry about. Just remember that as much as you want the car to go, you need it to be able to stop as well

[Bohemian_Funk]

There is, however, a minor issue on that note that was brought to my attention being that there WERE some '95s that had OBDII, supposedly. I can go over to my local Subaru dealership (almost literally a block away from my house) and find out when the swap over to OBDII happened like, tomorrow just to make sure. I need to find out to make sure my own personal chariot doesn't have the blasted system soon, anyway .

Also yeah, on the above note I'd suggest you do basically a full brake upgrade before doing any other major power upgrade as well, especially the brake lines. I know my stockers are in need of replacement, and my Leg's newer than yours. "You've played the demo, now buy the full game", as it were.
