Ive got a 87 rx7 n/a. s4 and im looking to swap in the turbo 2 motor. I was jsut wondering will i need to find a body harness off a turbo 2 and how much do i have to change if i swap in the s5 turbo 2. what will work the best??

 

well u might want to do a search but ill just tell u all u need is the engine harness and the ecu. But good luck on that and check out the swap how to and make sure u follow it for the most part

 

If he tries to swap an s5 turbo engine he needs to modify the wiring for the dash harness. It will not plug into the S5 ecu. If you did an s4 tII engine to a s4 n/a you would only need the ecu and the engine harness.
