I bought a 92-95 single cam vtec motor, I know its not much but it' better than what I have now.I have a 90 hatchback DX that is smoking like it has a drug problem. I wanted to know if the computers that you have would work with my swap?I am buying a si tranny and plan to use a MSD rpm activated switch to run the vtec.I am not to knowledgable about what computer will work so if you could help me out I would greatly appreciate it.Also,if your computer will work I probably will buy one.:banghead:

It would be less work and more cost effective to simply use the ECU for the 92-95 engine with a conversion harness to allow it to plug in. You do have a few hours of wiring to do this swap no matter what way you look at it.

p28=expensive
conversion harness=expensive
you'll still need to do the mpfi swap minus the resistor box

pm6+switch=cheap and somewhat easy, the hard part is modifying your distributor to fit (you'll need a pm6 one) it'll run alright with ghetto rig, but not as good as with a p28.
