What the hell is the difference? I understand that the OBD is off an early made car like pre 91... But what exactly is the difference between the three. Also what is the a P61, P72.... What are the differences there? The reason why I ask is because I am planning on putting either an H22A (H22A3 maybe) or maybe a B18C1 (Or B18C5) into my 1990 Integra LS 4 Door 4 Speed... I would also like to install the tranny that goes with the H22A/A3 or maybe a GS-R tranny with the B18's. Someone please this wanna be Honda Guru....
