    New Member Introductions
    Previous owner did a d swap into a 1991 honda crx si that I purchased from him. The motor is a d15B 3-stage v-tec with the stock Pm6-A09 ecu. It looked like he kept the stock engine harness too.

    My 91 civic has a d16z6 head on a d15b2 block. It was like this when i got it. instead of converting to the obd1 they ran the vtec through a msd ignition switch and kept the obdo harness.
