Could anyone tell me the the extra bypasses that would have to be done on a JDM B18C swap into a 96 Civic dx. I know everything that has to be done with the USDM. It's pretty straight forward.
Add Vtec wires
Add IAB wires
Lengthen some wires like O2 sensor
Remove 1 wire for the crank fluctuation sensor.

I know JDM engines don't have OBD2 ecus like we do in north america, so what else would I have to take into consideration if I were to do a JDM swap?

 

i'd look at the usdm p72, the jdm p72 that came with my friends motor was horrible. even my stock p72 made it run better. i heard about that online but dismissed it, but when we tried it out, the usdm counterpart really did make it run better.

i'd also put on a skunk2 manifold before i put the motor in, score a usdm harnass and obd2 to obd1 jumper.
