Hey guys, i have a 1990 toyota celica gts non turbo, i recently attempted a motor swap with the same generation 3sgt turbo motor. however things went really wrong with the wiring. SO i'm at a point now where i need to find a performance shope that can re wire the entire motor from scracth and also install and mod an mr2 tranny to the motor, any suggestions guys would be greatly appreciated.

Thanks

You cannot use stock ECU for it, you'll need ECU from the 3S-GTE you get or stane alone. I believe your stock tranny is good enough for the turbo.

i have teh ecu as well as all the resistors and sensors needed for the motor, i just need to find a place that knows how to do the job, the stock tranny will work, but the mr2 tranny is a bit more beefy and also provides me with lsd,

Oh so you didn't get the wiring harness. I believe MR2 tranny is a bolt on. As long as its from the 5S/3S engine, not the 4A. Axle is another question.
You got Toyota wiring manual?
