i just got a new rex yesterday! 91 Crx Si like the one i got now, but I am thinking about dropping a zc engine in since they only cost about 550, and i was wondering if all the engine mounts and wiring line up directly w/ the engine ? 89-91 DOHC obd0

 

yes u can use everything from the d-series engine.wiring harness,tranny,axles,mounts i wouldnt really use the stock ecu i would try to find a pm7 from ebay.

 

heres something you should keep...can't say I never did you a favor

I did it, its pretty easy if your mechanically inclined. You can run your PM6 ECU (stock Si) because its pretty much the same thing, but the PM7 is optimal.

optimal yes, but it runs much better with the pm7.

 

two wires to the external cam senser also.

research

 

the zc also comes witha boost chip i have heard. from friends but someone was saying something about cam sensor wires?

 

also do i have to re-wire some wires to the ecu?

 

no!just the wiring for your cps sensor.now if u have dx that diff story.ull have to convert it to multi point.
