With a GR42R turbo on my 20B will the large tial waste gate be enough to keep away the creep? I have been warned that it might not and I made need to run 2....That would take some additional fabbing onto my aspec manifold...
Thanks for the help.

 

It depends on how little boost you want to run. I believe C-Rock is having boost creep with his single Tial 44mm and T-76 @ 15psi.

 

Thats not good...2nd wastegate fabrication coming...
