Swapping From Internal To External Wg

[ovabooster]

Im going to get a custom manifold made up for my GT2835 in stock position. Should I weld the wastegate on the exhaust housing or manifold to suit? Which way will control boost better and will there be enough room to even mount it down below on the turbo?

For good boost control and even cylinder pressures, you'll need to make sure you can bleed exhaust gas off after all the primaries have come together. If this isn't feasible, then go custom or aftermartket manifold. And obviously, the turbo will need to have the internal wastegate flap sealed closed permanently.
