I have an 1990 Integra LS. I am trying to do a Ls\Vtec swap. I have a 1999 Gsr Head. a P72 ECU. My ?'s are as follows:
1. Will a 99 Gsr head (originally OBD2) work with a OBD1 ECU
2. Are all vtec solenoids the same?

I would put up pics but I haven't figured that out yet.

yes it will work with obd-1. all b-series solenoids are the same. also the d16z6 solenoid is really close to the same.
