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.

 

1. Yes it will run fine w/ an OBD 1 ECU

 

Thanks for the help. Do you know about the Solenoid though?

 

In comparing what? I dnt kno if the G2 and G3 would b compatible but yes any G# would b and a B16a,a2 or b would b and I kno tht
