what's up everybody? I hope I can find some help here. A friend and I just took out his F22A1 motor out of his 92 accord. This motor was trashed. He was not looking for massive performance upgrade just an "easy" swap. With a little research, we choose an F22B JDM Prelude motor. I am told it is the equivilent of H22 or H23A USDM. Long and short...Installed motor, bought P29 ECU (might be P39). Motor was running shitty with old ECU. New ECU masde a difference, but when I went to time the motor, #1 cylinder is firing sporadically with no pattern. I put the light on each of the other cylinders and they all seem to be firing properly. I feel like the distributor is the problem. I changed the wire on #1 and the plug. I also checked the cap and rotor. We had to buy a coiled distributor for this motor because the one off of the F22A1 wouldn't fit and the one that came with the new motor was coiless. We bought one for an H series with a coil. so, any ideas or confirmations? The next problem is the vacuum lines. The old motor had a different system than the new motor. Furthermore, the JDM had a different system than the USDM system. I imagine it's all about emmisions. How can we route the vacuum and return lines without having to introduce a bunch more emmision control components that the wiring harness is not equipped for? I think there must be a way to close the circuit or route without all the emmisions stuff because the JDM motor didn't have half of it on it to begin with. Any useful information would be appreciated. thanks.
