I used to have a 98 h22 usdm motor in my 93 civic 4dr, but blew a piston ringland and instead of fixing the open deck block, found it was more economical to just purchase a jdm motor. Well I did that, have the motor, it is now obd 1. What kind of problems does this pose now? Before i even had the first h22, when my car was stock i had a p06 ecu which is obd 1 and had it chipped to a p13 for prelude. im pretty sure the p13 ecu was still obd1, correct me if im wrong, regardless if my h22 was a 98. Question is my distributor on my new 92 jdm h22 has 2 plugs coming out of it and my old usdm distributor had 3 plugs, BASICALLY, EXACTLY WHAT MUST BE DONE TO TAKE OUT A 98 H22 OBD 2 MOTOR that had an obd 1 ecu and put in a 92 JDM OBD 1 MOTOR. please help. wiring diagrams, pictures, all of that if possible. Thanks

 

why not swap the distributor and engine wire harness? thats what i did on my h22 ek
