im buying a motor swap here soon but before i do i want to clear something up. if i buy a Jdm B16a, will it bolt right in to my 93 civic ex 2dr, and the swap comes with a new ECU can engine wiring harnest. but its JDM. so will i have to convert it to the Pasenger side of my car, cause JDM is right side driver. but i might also but a USDM B16a2, outa a 99-00 USDM civic si. will this motor mount right in my car, and how hard will the wiring be? because the USDM 99-00 civic si are obd 2. while my car is obd 1. so does a B16a2 reqiure much wire routing and changing. and what engine would you chose outa these two to put in your 93 ex?

thanks

 

with the JDM b16a you can use your stock wiring and just run the vtec wires. And for teh USDM b16 you would need an OBD2 to OBD1 conversion harness. I would just get the JDM one would probally be easier.
