Sweet!

So if it is a 6-port engine, then you never firgured out how to get the other 2 ports to actuate?

My understanding was that it had to do with some vaccuum switch.

But one could just as easily hook it up to the exhaust, and the drag at higher RPM's would do the job.

Let me know.

i'm thinking of getting mine off the car to find out what the previous owner have done with the aux ports.you may have right about the ehxaust hook up but i do not have the actuators for aux ports.as soon as i learned something more i will let you know.i may find actuators from 13b 6pi.

BTW.racing beat offers a performance header with 6port actuator or something like that.just check it out.
