I bought a rolling chassis that supposedly had a b18a in it before I bought it. It has all the b-series mounts and the wiring harness inside the firewall looks to be modified where the ECU hooks up. Also, the chassis is a DX but there is a resistor box mounted where it should be.

My question is what should my shopping list include to make another b18a plug and play?

here's what I have so far:
95 integra ls motor(bought already)
90-93 integra cable tranny
90-93 axles
90-93 int. shat
90-93 throttle cable
90-93 clutch cable
90-91 civic/crx engine harness(?)<--will the wiring harness from the ls motor work?
P75 ecu(?)
custom shift linkage

Am I right or forgetting anything? Anything that might make this easier/quicker?

The reason there is a resistor box and modded wiring is because it's probably been converted to MPFI which is necessary for any B series swap.

The harness will work with the motor but not the chassis. You MUST use a 88-91 Civic DPFI engine harness modded to MPFI. Any 88-91 Civic/CRX Si or 90-91 Integra harness will not match up at the shock tower plugs since DPFI cars have slightly different connectors.

The only way to use that ECU is if you convert to OBD1. A 90-91 PR4 Integra ECU will be plug and play with your ECU plugs but you will need to get an OBD0 LS distributor as well. It would be less work to go the OBD0 route but better off in the long run to convert to OBD1.
