do a search on ebay dude...its the cheapest place to get one....last one i got was like 45 shipped.
You will need a conversion harness.....and a dizzy. Of course a four wire o2 and E.C.U. and a little patience.
I think that is it....? It has been a while. D.A. :thumbup:
ok will the motor plug up?
The harness is plug and play...but I was thinking 90-92 were obd-0 and mid year 93 was obd-1...?
If you are not planning anything hardcore on tunning just I.H.E. then just leave it be.

www.rywire.com :thumbup:
wait, just re-read the post again.
the motor will go in no problem, just swap everything off the old block onto the new block and go with it, harness, distributer, alternator, exhaust.
^^^ :thumbup:
ya they swaped a b16a in it then it was stolen
but i have no other block i wrecked my old 91 and bought this 92 as a shell with wires cut here and there
so you have a 91, with a full donor engine correct? i mean, the whole thing is there, wire harness, and everything?

then you will need to get a abd1 engine harness, local junkyard would be the best find for that.
then you will need to get basically everything else. obd1 distributor, obd1 alternator, 4 wire o2 sensor, most likely another manifold or header with single o2 bung.
just hunt junkyards if you dont want to buy new. the block and intake manifold are going to be the only thing you can use from the donor car.
you cant use the obd0 harness, theres just no way to make it work.
i have greddy aftermarket 4-2-1 headers but should i just go pull off my engine harness then find one to put on it then buy all the other stuff
yeah, nothing but the block and the intake manifold are of use.
you cant plug the dizzy or the alt into a obd1 harness, and you cant plug an obd0 harness into an obd1 car.
the sensors and everything should plug in fine with the obd1 harness.
ok is an obd2 alt the same as obd1? and are my headers good?

The Alt are diffrent from obd-1 ver. obd-2. Headers...? J.K.
Yea the header will work.
ok lol so im about to go pull my engine harness out and pull my distributor,alt,and o2 sensor is that all i need to pull?

Have you worked on a B-series before...? We can give you all the info you got to learn some how :)
first, is the engine out of the car?

take everything off of it. take the wire harness off, the distibutor, the alternator, all you should have left is the block, head and intake manifold.
that is all you will need from it.

the obd2 header will work fine.
