I have a 94 Civic H/B CX with a blown 1.5L D15B8 70hp motor. Because of money issues, I am just going to swap in a 92-95 D15B7 102hp DX/LX motor. I would like to know what parts or troubles I will be encountering with this swap. Will the D15B8 ECU be compatible with the D15B7? Any smog issues I will have to deal with? Any info is greatly appreciated. Thanks.

that motor will drop right in. no swap trouble at all. the ecu will work, but i would get the matching ecu from the d15b7.

Yea the motor will just drop in but i recommend getting the ECU that was made for that engine.

Keep in mind you may have to do some wiring for a 4 wire O2 sensor, depending on certain items you may or may not use.

It would be better if you could list exactly which parts you will be reusing from the B8...

Yes, if you plan to use the D15B7 LX ECU then you will need to use the 4 wire O2 sensor and wire it up. That should be the only wiring issue depending on what route you take. If you use the D15B8 CX ECU you will keep the stock O2 and it will be all plug and play.

As long as the motor that you are swapping in is the same year or newer than your car and you use all the proper emissions equipment, there should be no reason why you wouldn't pass smog.
