Does the S4 N/A BAC fit on the S4 TII intake? Also, where does it fit, I am assuming on the side of the intake opposite of the TB? Just swapping in a TII engine into my B2200 that had a N/A engine before. I am running the TII engine without the turbo for now, so as long as it fits for now I am good, I am running the engine with a standalone. My TII engine has a blockoff plate on everything.

Also, I see 3 vac ports that are the size of the brake booster line, which one should be connected to the booster? What are the other 2 for?

 

the other 2 are for AWS to the intercooler.

the BAC will work but a) you lose idle speed control air bleed and b) you need to flip the elbow on the BAC.

 

I can fine tune my idle speed with my standalone using the BAC, and to get close, I should be able to adjust the throttle stopper, correct? Just much more of a pain to adjust the idle that way.

 

yes
