Ok so here we go , my friend just bought a 96 zenki and just like most of the people , he chose to go SR . I can get his engine for almost nothing and it will be much more reliable than my 89 ka-e (for turbo applications) . I was wondering if its more simple to bring the new engine to obd 1 than to keep it obd 2 . Also , which parts make them different ( i know for the diagnostic port ,but around the engine ? Intake ? what else ? ) I've never had a obd 2 car so I still have alot to learn about that . thanks for any help and forgive my bad english !
