Well here is the scenario..
1994 Civic VX (VTEC-E) that will be getting a B18C1. I figure that I can get a s2k intake mani and disable the IABs, and if i get a chipped p28 it will disable the knock sensor. So all I wuld have to do is plug in the wiring harness together and I am done. I think Tom (b18c5-eh2) said something like this could be done for an ITR motor.
So what do you guys think - I think i can sell my p72 ECU for at least $300 and get a p28 + chipping and get the s2k mani later with other money since i planned on getting it anyway later down the road...
so

Although, you will have to do something about the 4 wire 02 sensor. I believe it needs to be repinned a different way for the VX chassis only.

Yep, this setup you speak of will work.

4-Wire 02 sensor - does that mean that I take the wire from the GSR engine harness and re-pin it on a diff. location on the chasis harness...?
BTW katman - you got an IM, an offer regarding your chipping services..

Not to hijack this thread, but I am doing this exact same setup - but in a 92 CX. Am I correct in the assumption that all I'll need to wire is VTEC and rewire the 4-wire O2 sensor? Also, whats this about all 92 Civics being prewired for VTEC and how does this help me?

yes, all 92 civic hatchbacks (at least), all models, have vtec embedded in the wiring underdash/ecu to shocktower main harness plug. So, all you'd need to do is get a hold of a vtec engine harness from an Si or EX, plug it in, and your set....only sensor you'll have to wire up is the Knock sensor though...unless you run reprogrammed P28 ecu since that ecu and program dont use a knock sensor.

what about rewiring the o2 sensor. i have a 92 vx and i get a code for a o2
But I think if you picked up a 92-95 SI/EX harness, you wont have the 02 issue.....but that's kind of a dumb idea since the VX harness is already vtec equipped..
Thats what I figured. I am going to be running a Kenji P28 with a Skunk2 mani. so that solves that problem, but does the fact that the motor is a 99 OBD-2 complicate things at all? Would I be better off to run a OBD-1 Si/EX engine harness and repin dist. and change injector clips?

Hmm...nah, stick with an OBD2 integra engine harness. It's compatible in an OBD1 vehicle. Plus you wont have to go searching for an OBD1 distributor, injectors, etc. There's 1 or 2 plugs left unplugged/dormant, when using an OBD2 integra engine harness in a 92-95/OBD1 civic/integra.

Excellent. That said, will I need to repin the VTEC wires to the correct plug location at the shock tower on the OBD-2 harness - or are they already in the correct location to match up with the stock CX harness (shock tower to ECU section) if I use a P28 ECU?
