hello there i have a 97 integra that i picked up with a blown mkotor.. rod went through the block. I have a 94 ls which is obd1.. how do i make this a clean swap. i know the alternator plugs and injectors are different. im not worried about that. im worried about breather for the pcv, vacuum hose and crank sensor connector.. car wont start without the ecu seeing the crank sensor input.ere help me out here. its been a while since i messed around with swaps and integras.

 

If you had the engine wiring harness for the b18 it'll be plug and play.

 

swap the oil pump, intake manifold, all sensors, Distributor, injectors, and wiring, basically everything except block and head from your existing OBD2 97 engine onto your newer OBD1 engine.
