I am almost done my 4g64 turbo conversion. That last thing I need to do (other than the downpipe to the exhaust) is connect the bypass valve host to the intake. I used the 4g63t throttle body. Can I connect the hose to the 'P' port? It's currently unused and capped. If not there, do I need to tee off one of the other hoses to the intake? I would appreciate any info from those who have done this conversion. Thank you.
 
Here’s an old article about vacuum diagrams.


Since I’m unsure of what vehicle or generation of engine/head you’re using. Here’s a couple screenshots I took to highlight the vacuum line location for the blow off/bypass valve. Hopefully that’s what you’re looking for.

Thanks Derish. My 4g64 intake doesn't have as many ports as the turbo intake. I was going to put a Tee on the Solenoid Valve line or the FPR. However, I thought, if I have a spare 'P' on the throttle body, it might work.

Oh, so you don’t do a head swap? Or the stock intake works? My bad, Guess i need to read more about that but it’s not something on my future needs list.

A thought, stock manifolds are cheap and available from like every DSMer on earth so maybe you could grab one with more ports?
