How many lbs do you plan on boosting? High boost i'd go external, lower boost around 5-9psi internal should be fine except for the occasional boost spike depending on whcih turbo u are using.

External, placed correctly is supposedly better. I cant back that up but Ive read of people running internal WGs on older turbos and they seems to have boost creep/spiking issues.... I know my buddy has. Im running the 38mm Tial and Ive never had any issues...

don't mean to jack but i got a question along the lines...
If u buy a turbo with an internal wastegate cna u just rip the actuator and the arm off of it and some how close up the wastegate? also i heard that if you ARE gunna use an internal wastegate i heard that u need a custom turbo manifold to allow for the bigger flange?
info would be awesome!

Ive seen people make an internally wastegated turbo external. It usually involves removing the arm and leaving the flapper and just welding that to the exhaust side, Which is usually cast 
. Just buy a turbo thats already externally wastegated.

yeah...i'm basically done with my turbo build, i just can't adjust my turbo to a good position for some reason with an internal wastegate. I've gotten advice to make the arm a little longer so the wastegate sits a little farther away from the turbo. It's just more of a hassle, if i could do it over again, i would've went with an external wastegate.

It depends on the turbo. On my turbo (T3 .48/.60) the internal wastegate actuator and flapper were all removable from the turbo. All I had to do was unbolt them and take them off to run an external wastegate.
About the "custom" turbo manifold for an internal wastegate. Not true at all. The turbine inlet flange is the same for internal and external wastegate turbos. The only thing different about the manifolds is, with an external you have to have an external wastegate flange on the manifold, and with an internal wastegate you don't need that flange on the mani.
