Those dual w/g holes don't do jack for me. :rant: A full 3" exhaust with an intake but no TID yet and it boost creeps like a ****. I have a BNR Stage2 waiting to be put on. The w/g are going to be a bit larger. :twisted:



Gigady gigady gigady. All right!

Is all in the turbine housing and exhaust manifold the difference as some have already stated. The cartridge and compressor housing area the same between s4 snd s5.

Can you even go past 8psi without porting the wastegate?I thought you had to port it to go past 8.

If you don't port it, it'll go sky high. :smirk: When it's ported it's easy to control it.

my unported 87-88 turbo would hit 11-12 psi in the midrange with an intake and catback
