I posted this in the forced induction forum, but didn't get any responses. Im getting ready to have my turbo manifold made and was just wondering what size tubes or primaries you big turbo guys are using? Will be going on stock bore B16 for now, but plan on building bigger motor.

 

22inch

 

meaing 2"

 

1.5 i/D

 

Quickwhips, thanks for the reply. Anyone else wanna give there input?
