engine swap

I have a 92 Talon non - turbo. I just bought a wrecked 93 Tsi. I want the turbo charged engine. Do I need to pull the whole wiring harness from the 93? I believe I need the 93's ecu? Please help, anybody. Thank you very much.

if the frame/unibody is straight on the tsi it would be better to just swap all your body panels

to change the engine you're gonna need to change

engine
wiring harness
ecu
exhaust
intercooler

and thats just the stuff i know youll need

or you can just buy a turbo kit from hahn racing, i think they make one i know that somebody does
