Ok so Im thinking of putting in that B18C1 Vtec GSR I have bc I cant seem to sell it. I have a 1990 Integra. To my understanding I will have to do OBDO to OBD2? I have done alot of google research but there is so much that says it can b possible and it cant an so on, so I dont know what to believe. If someone has accomplished this what all do I need? If someone has already done this and already knows the full list that would be much appreciated. Also someone with a rough estimate of how much this will cost would be great. I know I will need a GSR CPU and a different harness but im not sure what kind. Thanks.

 

what if I convert my car to OBD1? wouldnt that make the swap easier?

 

you should just convert to obd1. May need to swap few plugs off the gsr harness onto yours, get a jumper obd0-obd1 harness for ecu and obviously an ecu for it. A p28 with appropriate software will do you just fine.

 

k thanks

 

Yep ! for your case P28 ecu + obd0-obd1 is good ! obd2 your car will turn into a xmas tree
