well im going to try and word this the best i can an write this to the best of my ability. first off i am experienced with rx7s and have had 15 over the years so feel free to make fun if i sound stupid.

my question is as follows : what injectors or what do i need to do to make my car work.

background: car is a 1987 rx7 turbo using a s4 wiring harness. I have picked up a power fc for the FD and the seller included a complete s5 wiring harness and converter harness from banzai racing for the s5. the motor im going to put into the car is infact an s5 motor. the car still has the resistor block installed, the harness that the seller provided also has resistors. the injector clips are missing but i have tons of s4 injector clips. my problem is i dont know what to do with what i have. i am going to have to use the s5 wiring harness because the motor i have has all manifolds sensors ect.

agian my question is what do i want to do for injectors. do i remove the banzai resistors or do i need to remove the resistor block from the car.

EDIT : if i have missed anything or didnt explain well enough feel free to ask

 

You can't use the S5 engine harness or our S5 adapter in an S4 car, the dash and engine harness connectors are completely different.

Use your S4 engine harness and buy the replacement S4 adapter harness. The S4 Adapter has the ability to wire in the S5 TPS, however you are going to have to ditch the OMP.
