Hi Im buying a sr20de silver top, jus the engine, Im wondering what I need to change for it to fit in my s13 coupe. And also what parts are needed since it is jus the engine, I know I probably need a wiring harness and what else? A guy who works at a nissan dealer said a wiring harness from a ka24de will work for it, but Im sure it doesn. If you have info for me that would be great. Thank you everyone!!!
