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
