so i checked some websites because i'm looking to purchase a super 20g but i'm only seeing them internally wastegated. i want to go external so i was wondering if they sell any super 20g's without an internal wastegate or do i need to modify the super 20g to make it external?

and with that said, does anyone know any good websites for good priced well made exhaust manifolds for 35-38mm external wastegates?
 
if youre going WG off the manifold you can just weld the flapper closed on the turbine housing-- if youre going WG off the o2 then remove the flapper from the turbine housing

either way you can just remove the internal WG--

i like extremepsi, map, forced performance, and punishment racing.

how much boost do you plan on running?
