i have a 99 interga LS and i am going to swap in a gsr of the same generation. im wondering if anyone can basically give me a list or a rundown of everything i need to do this swap so i can do it right the first time. i know i obviously need the motor tranny, ecu and axles i assume but what else as far as wiring and anything else i may need to do this swap correctly the first time. if anyone could answer this or tell me somewhere i can go on the net to find out id greatly appreciate it. thanks alot.

 

I live a mile away from Crownsville. I can help you if you want. You will need the ECU. You can use your ls axles. Does the gsr motor come with the engine harness? is it a USDM or JDM motor?
