:::HELP:::1992 legacy 2.2L turbo conversion

Kawikid20o2 · 05-02-2005, 03:09 AM

I have the ECU,turbo, injectors, headers, and up pipe from a '90 usdm legacy turbo and the intercooler from a 2004 wrx. Can these parts be fitted together to convert my 1992 legacy 2.2L or am i missing something huge? Any information about the restraints that i will have to follow to do this safely would be greatly appreciated!!!

You are trying to piece together a kit, but those are not the components I would use. The swap would be easy if you had the whole engine. Because you are missing some of the vital components, this is not going to be easy. You can't just add the up pipe to a NA exhaust system. Also the injector rails are different for the N/a and turbos, so just having the injectors will not do you any good. You might head on over to: bbs.legacycentral.org and look around

im sorry, i do have the fuel rails with the injectors and the turbo exhaust manifold and upipe are also together. The only thing i do not have is a down pipe which i was told a wrx down pipe would bolt on to this turbo vf 10 or vf 11 i dont know which it is.

You are going to need the turbo cross member out of a wrx or older turbo legacy. Also, there was never a 90 turbo legacy, 91 to 94 were the years for the turbo legacy.

Kawikid20o2 · 05-02-2005, 06:38 PM

well then it must be from a 91, how can i tell if i have the turbo ecu or not?

You also need the wiring harnesss - you can't just plug in the turbo ECU to your NA harness. Honestly, it would be much cheaper and easier to just buy a legacy turbo and sell your Legacy. Also, you'd get a better transmission, brakes, and suspension.

Kawikid20o2 · 05-02-2005, 09:35 PM

what if i scrap the ecu and go with the n/a ecu that i have and use a greddy emanage?

subiekid · 05-02-2005, 09:46 PM

The turbo ecu on your motor would run like ass. The CR of the turbo motor is much different from the n/a motor.

Just sell your car and buy a turbo legacy.

Kawikid20o2 · 05-02-2005, 10:12 PM

so your saying this is a horrible idea all together and that i should scrap the project. Turbo legacys are rare, the only ones i have found have lots of damage or blown trannys or bogging engines. But if you guys say that this cannot safely be done then i will have to find something else to mess with and ill just sell all this crap.

but what about using the greddy emanage, i have seen the following set up on a 1995 ej22e

td04 turbo, wrx intercooler, greddy emanage, greddy type s BOV

running 5 psi and all is good so far

what do you guys think?

reddevil · 05-02-2005, 10:30 PM

If you run 92 plus octane the ecu should be ok. I run up to 7psi on the NA 1990 ecu but with an intercooler. I was running 4psi w/out an ic with no problems. But the moment I boosted over 4 psi I needed one ASAP. Upgrade the fuel injectors (which you have) and the fuel pump. Add at a minimum a 1-1 rrfpr and always run high octane.

It will work and at 4 psi you will gain about 40 hp.

Kawikid20o2 · 05-02-2005, 10:51 PM

red devil, did you say that the stock ecu would be ok without emanage or anything or with emanage...by the way i will also be running a 2004 wrx intercooler.

reddevil · 05-03-2005, 01:21 AM

I ran 4psi with no engine management. It worked. I am not saying it is optimum. I currently am running 7psi with upgrade injectors, fuel pump, AWIC and 2.5 exhaust, all on stock ECU, no engine management other than turning downt the MAF signal about 5%. I am also about 3-4 weeks from my 2nd engine rebuild. Knock aint good.

Less than 5psi should be fine if running 94 octane on boost if you have no way of retarding timing. Get a perfect power or something if you want to run higher boost.

I am currently sourcing some turbo pistons so I can run 10 psi on the NA ecu. This should be about a reliable 160-180 whp.

Kawikid20o2 · 05-03-2005, 03:42 AM

why do you need to rebuild? what caused this? overboost? Im trying not to cause problems...thank you for your help!

also i need a down pipe still...does the wrx TD04 bolt pattern match up to this turbo? vf-10 or 11 idk
