Hello, I need some info from the guru's here. I tried to search but didn't find what I was looking for. I have an 86 CRX Si that burns alot of oil, and the trans gets cranky when I shift too fast. I just saw a 90 2wd wagon with body damage that I can get for really cheap. My question is this: Does it make sense to swap the motor and trans from the 90 into my 86? I think they are the same size, 1.5L, but I don't know if there are any cam differences or anything else that would make the 90 engine less desirable. I am not looking to make a race car, I just want an easy swap so I can keep driving my CRX and getting 38-40 MPG. Any other things that I might run into that could complicate the swap? I could either keep all the 86 electronics and just swap the motor, or do the whole swap and take the ECU from the 90 as well. Just don't know which is the better option right now. Thanks in advance.

 

OK, did some more searching, and found that I currently have the EW4 motor, and the 90 motor is the D15B2. Slight differences in power, but still can't figure out if the swap is going to work easily.

 

Anyone? possibly getting the whole donor car for $300, but I don't want to do it if I can't get the swap to work.
