Scenario:

I have a 1992 Civic Si hatch, bone stock, a complete B20 long block , and a complete wrecked 94 Integra LS with a 5spd, untouched.

My plans are to sell the B18 out of the Integra (74k miles for anyone who's interested), replace it with the B20, and put that whole swap into the civic, after which i'll sell the entire drivetrain out of it (right at 100K miles).

A few questions:

1. Which wiring harness will I need to use, if any, or will I need to find another wiring harness?
2. Do I need an OBD2 ECU for this engine, since the B series swap is OBD1 but the B20 is OBD2
3. Will the a/c, alternator & power steering, off the Integra, work on this B20?
4. Will the integra motor mounts work?

Any help you could offer is greatly appreciated.

1) ur eg is obd1 with vtec harness, ur integra is obd1 non-vtec harness, ur b20 is obd2(a or b) non-vtec harness. use the integra harness IF you dont have b20 harness
2) u can use the b20 ecu if u have it and do a obd conversion harness to the b18b motor harness or use b18b ecu with b18b motor harness but using ur b18b motor harness, u'll need to splice some wires
3) i dunno about the a/c, alternator, power steering but im pretty sure u can
4) u can use ur eg mounts

id say do the b18b swap...pretty str8 forward

The alternator won't work nor will the distributor. So I've heard from many people. You'll need an OBD1 parts for that. I'm not sure about the A/C or power steering, who needs that anyways?

You'll need Integra B series motor mounts, the LS mounts will work just fine bolted onto your EG chasis for the B20.

I'm doing the same swap into my EG. Good luck!

Thanks for the advice. I've decided to sell the B20 longblock, and drop the B18 swap into the Civic
