tryin to figure out ENG/ECU origin

randdaman7 · 11-30-2010, 11:03 AM

Hey guys, I recently bought a '98 Forester 5spd here overseas(jdm) and trying to figure some things out. Currently has a turbo EJ20-something. The VIN plate says EJ20J which was an NA motor so I can find from searching. I believe the motor was swapped as a whole at some point and not just a turbo thrown on. The motor in it is DOHC, with the old style MAF that bolts to the airbox. spark plug wires on the intake mani. I cant find any numbers other than the EJ20 on top, gotta do some extreme cleaning.

The ECU, from what I have found, is what i believe to be the original for the car. I didnt think that this ECU would work right with a turbo? maybe this car is an original turbo model? heres ECU details. Ill try to get a good pic of the ECU, cant right now.
4W
22611 AD412
A18-000 DQ0

Basically trying to find if this ECU is original, and maybe Im wrong about the EJ20J bein an NA motor? Please correct me if im wrong about anything. Thanks

Yahoo auctions tells me that's a 97/98 SF5 5 speed EJ20G (turbo) ECU.

Turbo Foresters are VERY common, so it could be the original one. Do you have a picture of the chassis tag?

Is your ECU located on the engine?
