WilliamMunny Posted July 7, 2010 Share Posted July 7, 2010 What is different about a JDM motor? Is it just the wiring/sensors? Can I use the pistons, heads? What about the block? Most of the ECU harnesses attach to the intake so if I use my intake am I in the clear? Link to comment Share on other sites More sharing options...
Reuben Posted July 7, 2010 Share Posted July 7, 2010 Vague questions will yield vague answers. I think the CR's are different, heads will be more or less the same, sensors the same. Looms similar, except around 95-99, where USDM went OBD-II, but JDM lagged behind. ECU's are tuned for 100 RON, which is what... 93-95 MON? Maybe less. Turbo looms obviously are different to N/A looms, but in some cases it's merely wiring for the Boost contol, and pressure select solenoids, and a few other things. Engine bay wise, turbo's have different gearbox's, with push vs pull clutches, cable vs hydralic etc. The brake boosters are different i think too (turbo being bigger?) then there's the LHD/RHD thing. Also turbo crossmembers are different. Link to comment Share on other sites More sharing options...
