im putting a jdm ej20T from a 1994 subaru gc8 in my 1994 impreza, i was wondering if this will require replacing the ecu, if so, could someone link me to a site to buy one? ive looked but could not find one, im pretty sure i have all the other part i need, i bought the whole front end of a gc8, well up to where the firewall starts, the firewall is not intact and theres no dash parts, but i dont really need those, anyway, yea was just wondering. if anyone knows please help, it would save me time trying to match up the pins if i can just get away with replacing the whole ecu

yes you'll need the ECU, did you try ebay yet?

It;s the kind of thing you will most likely have to source a car to pull it from. Not quite a shelf item

Its from a 2002, you will have to find out if it will work or not.

 

You can also search this forum for it.

well im putting a jdm ej20 t in it, do you think this would work? http://cgi.ebay.com/ebaymotors/98-99-SUBARU-WRX-STi-V5-ECU-M-T-JDM-EJ20-Turbo-Computer-/280478047767?pt=Motors_Car_Truck_Parts_Accessories&hash=item414dcb5e17

oh and thanks for all the hlep guys

Probably, but its awfully expensive.

I would try calling a Subaru shops to see if the ones above will work or not.

PIA

Smart Service

AWD Auto

Outback Automotive

These are all in the Puget Sound area.

cool, thats not to far off either, i live in central washington. and im gonna try to get him to go down on that ecu because theres an OBO offer, so i offered him 250, which wouldnt be to bad, that 550 that hes trying trying to get for it is way over priced

The ECU will depend on the wiring harness you're using.

 

And you will need the whole bulkhead harness for the swap.

 

 

If you don't have a bulkhead harness, I would highly recommend getting a harness and ECU out of a USDM WRX. Better wiring diagrams, better support, and Open source tuneability.

you guys think i should go with this? its the whole setup including the transmission, i dont need the awd trans. but i can always sell it.. http://cgi.ebay.com/ebaymotors/JDM-EJ20-Turbo-GC8-WRX-IMPREZA-2-0L-DOHC-92-95-Engine-/380336855598?pt=Motors_Car_Truck_Parts_Accessories&hash=item588dd7da2e

now im just hoping i can win the bid on the damn thing lol

don't you already have an engine? Seems like a pretty difficult way to get a harness and ECU. Just start watching the classifieds on nasioc, you'll find somebody who wrecked a bugeye before too long.

nah i havent ordered the engine yet, thats why i was wondering if i should just get this one. this one looks promising because it has everything all ready to drop it in. so i might just end up getting this, that way i have an extra trans.
