Maybe I should just do a couple more mods to this motor and let that be that. Header, lsd, flywheel. Maybe head and cams, then done. The car is getting up there in age and miles (76K). I can't decide what to do and I don't have a huge budget for this car. Uggh!
You'd need the 23 pcm to run the imtv that the 23 has. Or you could run the 20 manifold on the 20, but that is one of the +'s of the 23. If you like your zx3, Then why not go for your mods then? Price out a 23 head & then a 23 motor to give you an idea on cost. Get a Fwerk's header going plus a stealth muffler.
