Ok so basically I hav an s14 shell and i want to drop in an rb25. I have the motor and transmission along with all the wiring harnesses. My question is can I just drop in the motor and run all of the rb wiring? It's a drift car so it just needs to be able to run? Also, what changes will I have to make to the power steering?? Thanks

For power steering you can use the KA pump and original lines. No changes required.

As far as wiring goes, you'll need to modify the harness at the passenger footwell chassis interface plug. (M63 plug) The S14 chassis interface pinout doesn't match the RB. You'll need to swap some wires.

RB wiring won't match up to the fusebox connectors or windshield wiper amp. It'll need to be modified if you intend to use windshield wipers, oil pressure sender, or trans sensors (speed, neutral, reverse lights)
