Ok I have decided that since I need a new Fuel Injection System I might aswell go and upgrade my DX to an Si one. Now after alot of searching I found a complete setup for the MPFI. Now honestly I dont know much about stuff on CRX engines. I can do all of the bolt on mods but when you get down into sensors, wiring, etc it like looking at a blank piece of paper.

So who has done it? How much is the MPFI worth? I can get one for $150 CDN which is about $110US. Is that a good deal? Should I keep looking around? Is there a place online where I can get the swap details? How long will it take me? Should I just give up before I start? Are there other MPFIs that will work with my CRX engine, like a 92-95 Civic? Where are my pants?

parts list

88-91 si or hf dizzy (has cylinder positioning sensor)
88-91 pm6 ecu ( 90-91 if you want to chip it)
88-91 si intake mani (have seen people do d16y8 manifolds)
injector resistor box
throttle body
all sensors on manifold and throttle body

there is a few places online that have a write up about the mpfi swap. do a archive search in this forum for mpfi, there is a lot of good info and diagrams around on here.

btw have you checked your body for your pants?

I can get all of these from a 89 CRX Si right? This is the car that I will be getting the MPFI from.

Thanks for your help. I will check it out online and do some searching.
