I've had a 1st gen B16 swap for a while and I have a B20 throttle body and a P30 intake manifold (and gaskets of course). I'm going to port match it tonight. I've got the vacuum lines, map sensor, and the valve under the throttlebody that uses coolant temperature to control idle at cold startup (I can't remember what it's called for the life of me) figured out.

My only real concern is whether or not the PR3 fuel rail will work on the P30 intake manifold and now that I think about it will the idle air control valve on the back fit?

 

It will work.
