Is this possible. you just tap the runners for vacuum and have it go to a chamber of some sort? Any one doing this. Could i run itbs with a vafc? I got a stock gsr that i wanna upgrade. What kind of cams would be good for my setup, itr/ctr, skunk stg1,2,or 3? Hmm. What's the basic minimum that i would need to the the itbs running on my gsr, cause im gonna upgrade slowly. thanks

 

later i plan on pnp for the head and either itr or ctr pistons. are topline itr pistons anygood for the setup?

 

yeah you should be able to do this...i heard it wont idle that great but who cares
