Default Can I use the PR4 to run a VTEC head???

Can I use the obd0 PR4 to run a VTEC head or do i need to run a pr3

If so, then how?
Do I must have the VAFC to activate it?
or Is there some sort of rpm activated switch you can use?
Does anyone know what the green plug on a 90'b18a1 block is?
if anyone is running this setup or has info, please post!!

I have a B18A1 longblock in my car.. soon will be LS/VTec'd.

As far as VTEC from a PR4, no. There are efforts being put forth finish VTEC from a PS9 (90-91 EX Automatic) which could be used to power your B18A1 VTEC.

Check out http://www.PGMFI.org and search for 1wire VTEC, and http://www.TurboEDIT.org for the software to do it.
