Hey everyone, its been a while. I just recently got more time to worry and work on my project. Here is the current situation and my questions regarding it. I have done some searching and havnt found much:
I have a 86 NA FC. I bought a S4 engine and and tranny (supposedly, though unsure of the exact year) from Tiger Direct a while ago with the ECU, no harness. Bought it about a year ago. Me being a dumb **** (and lazy), didnt send the ECU back to them because funny thing is, they sent me a damn FD ECU, lol
I have rebuilt the engine and it is sitting there, wanting to be used now. My biggest questions I need help with is regarding the ECU and harness. Can I use the N333 ECU? And as for the harness, can I use a US TII one? Also, I read way way back that someone said it is possible to tweak the NA harness itself to get it to work with a Turbo ecu, etc. Is this true? I really really want to get this thing finish so I can finally drive it. Been sitting around for almost a year and a half. Freakin dream car wasting away, lol. Im so dumb. SO YEAH, any help at all would be absolutely great guys.

Search for "turbo swap" and you'll find a million other threads.

Use N332/N333 & the NA harness.

 

Thanks so much man. I must have been searching for the wrong stuff. Was putting in ECU and wiring harness stuff. Was late=getting stupid, lol.
