Swapped my motor from 91 to 92 vtec not kicking in..

[simply vtec]

Ok i swapped my 91 b16 out of my integra and put in the 92 b16 and my vtec wont kick in. I read that it might be the o2 sensor. Im hoping its not the computer. Any one run into this problem or have any suggestions...

I assume you are using a B16 ECU or a chipped ecu flashed for Vtec. Are you wired up for Vtec and do you have a knock sensor if you ECU looks for one?? I also think that 91 is OBD0 and I know 92 is OBD1. you will need to run the proper harness and ecu combo and may even need to do some rewiring. But start simple look for anything not plugged in. Check for ECU codes that can help you diag the problem.
