How much work is involved in swapping a d15 vtec into a 92 civic hatch. The vtec i got has a flex plate like an auto matic on it. can it be done? The tranny i got is a five speed stock tranny will it bolt up? can the vtec be run with stock harness and ecu until i got more money?

If you are talking about putting in a d15b vtec, then it's easy except for the vtec wiring, it uses the stock mounts and everything, your stock tranny will bolt on .

It seems as if the wiring looks the same can I use the stock wiring harness from the car or do i gotta find a vtec ecu. Im really not looking at performance at the moment?

You need a vtec ECU for the vtec to work. You can use your existing engine harness, but you need to run wires for vtec. Check here for wiring: http://www.hondaswap.com/~pills/obd1guide.html
You jsut need to run the wires to the correct pins on the shock mount harness, because all the '92 civics came with vtec prewired on the ECU side of the shock mount. So just add the wires to the actual engine harness to the correct pins.

does any body knows if the d15b vtec will work with my civic and if the wire harness will be the same for the engine
i intalled my engine alredy but i just need some help with the wires staff
can any body give me a hand with this thanx

Try making your own thread instead of bringing back an old one from 6 months ago.

What ECU are you using? What car is it going into (CX, VX, DX, LX, EX, Si?)?

i got the vtec ecu and is for a 92 civic lx

"vtec ecu" doesn't say anything, read that link and you'll see why. And you'll need to add the wires for vtec from the engine side of the harness to the correct pins on the shock tower mount connector. Honda prewired vtec in all '92 Civics, but only from the engine bay side of the shock tower mount connector to the ECU. So you'll still have to run the wires from the engine to that connector. Like in this pic: http://www.ff-squad.com/tech/wiring/obd1.shocktowerplug.jpg You'll see it wired like on that bottom part of the pic and the other side of the connector will have black plugs covering up the wires, you'lll need to take those plugs out and pin the wires in those spots.

do you know if thats way it will not star
and is there any others cables that need to be
instaled?
thank you i aprecite your help a lot
