The original D15A3 decided to die on me in my 1987 Honda CRX Si. I was just wondering if the JDM D15B swap is do-able. I have heard tha you can just bolt in the long block using the D15A3 mounts, using an OBD-0 (Pre OBD) to OBD-1 harness, p28 ECU and then wiring up VTEC. Does this sound right? Has anone else had experience swapping in another SOHC motor into an 84-87 Civic/CRX w/ fuel injection? Any help on the matter would be greatly appreciated. Thanks in advance.

 

first of, you'll need a P08, not a p28 cause the p28 run with two O2 sensor.
second, I'm really sceptical with the moun't, if you keep the same trany, ,that should not be very complicated but upgrading to a diff gen trany will let you down with a lot more mount to deal with.

hope this help,
