Default D15B in a CRX

im putting a 1.5 L D15B vtec-e in my crx, just wondering if anyone has a wiring diagram so that i can wire it?

im putting a Si Cable tranny, clutch and flywheel, instead of getting the hydraulic/cable conversion..... im pretty sure the stock mounts will work... cleaning motor tomorrow, gonna post more pics of everything else tomorrow.

its the only motor i have in the garage that runs...so instead of buying one, just make that run and just sell it.... i know its not a fast motor swap or anything...just want it to run... plus it gets 55 mpg on the highway, thats so awsome. with gas prices going back up

you're gonna have to convert to obd1 and then at least wire VTEC, VTEC pressure switch, and some extra O2 wiring for the 5 wire if you use the D15's correct ECU

I do make a harness for the z1 ecu... give me a call or pm. Basically there is seven extra wire for the 02 sensor, egr, vtec, vtec oil, and some other light changes, and of course converting to obd1. its kinda a pain in the ***, but totallt doable.

no plug and play, if it where me, i would just run a chipped ecu, set vtec around 2800rpm high load, and around 3200rpm low load.

disable the o2 heater, and run it like that, good for 35+mpg with the SI trans.

oh wait.......... that is what i did.

i sure didnt, look at the post times, LOL, we were typing at the same time, thats awesome that you can build a harness that has all the EGR, and wideband stuff though, you should advertise that stuff.


wink wink.
