I have an ODB1 gsr engine that i want to put into my ODB2 integra LS i was going to just keep the engine obd1 and purchase and obd1 engine harness, dizzy, etc etc and run hondata will this all work out fine or do i have to convert everything in the engine over to ODB2 to work in my car just looking for opinions and direction thanks

 

two options A: use the obd1 parts, buy a 94-95 gsr harness, both pieces, and a conversion harness with obd-1 p72. easy plug and play. Or B: change distributor, alternator, injectors , and buy a obd-2 p72. But, that is the harder way, and you have to wire vtec and knock and iab's etc and another o2 sensor, plus CFS sensor, so , i would go with option A. Remember, integra's have 2 piece harnesses, which seperate at firewall.
