The MPFI swap sounds interesting how would i go about looking into doing this, are there any sites or places i can check out to get an idea of what has to be done in order to achieve the MPFI installation correctly

thanks for the help guys

are you just wanting to swap the intake manifold/TB or are u wanting the whole motor??

From his previous posts, it sounds like just the manifold.

To put on the mpfi manifold, you need the manifold, injector resistor box, and the Si ECU. There is some site here that walks you through how to do it. I dont remember it off hand, but I am sure someone will post it. All in all, you are looking at about a 2 hour job.

oh sorry...i guess i didnt see his other posts.:(

The MPFI makes a big difference in the throttle response, in my experience. I had to do this when I put in my ZC. You will need to add all of the things mentioned before: Si or 1G Integra ECU (the integra ecu has higher rev limit and better fuel mixtures programmed), the manifold, the resistor box (I am using a prelude box, it apparently doesn't matter what honda it comes off of...), and then you will need to rewire. You can find directions on the rewire at:

I would get someone who knows what they are doing to help you if you are unfamiliar with what you're doing. I did, and I am glad that I did.

Yeh i think ill hold off on the mpfi swap my buddy is gettin a JDM motor in next month for his swap and he'll sell me his ZC and ill get the box and ECU then.

im kinda farmiliar with this shit just its really frustrating working on it
