Thanks for your replies, I actually already have the 96 GSR motor. so thats why I was hoping to get more info on the swap. Some one else has told me I can use most of the Si's wiring and cut the plugs off the 96 GSR engine for injectors and add a wire for the knock sensor. Arent the engines pretty much the same except for the extra sensors for OBD2? can I just not ues these sensors? since I have a 95 GSR ecu?

TIA
Anton
