S15 SR w/5 speed into S14 ?'s - Zilvia.net Forums | Nissan 240SX (Silvia) and Z (Fairlady) Car Forum

Hey everyone,
Long story short, I have the opportunity to purchase a s15 motor with s14 5 speed trans.
I recently blew my s14 notchtop SR, which is why I'm looking for a new motor. The motor is cheaper than rebuilding the S14 SR.
Anywho, would the wiring be straight plug and play? I believe I need to keep the s14 coilpacks (correct me if I'm wrong), but would my NA ECU still work?
I'm also currently using the wiring specialties harness.

Any info is well appreciated.
Thanks!
