Re:Internal or external wastegate?
 
IMo it depends on what kind of set-up you are starting.

If you are going HF with a T25, well then go internal cuz you don't have a WG flange on the mani, and hte turbo comes with one.

If you are going to drop some money on a custom mani, well then go external even if you don't use it, you can just block it off easily, you can't add one on as easily.

To be honest i think i would rather have an internal with an enlarged hole/flappper like a lot of dsm guys use

how exactly can i enlarge my hole/flapper? i got an edelbrock kit

with a die grinder, then you either would make a flapper or buy a larger one. Sometimes you see places selling exhaust housigns with bigger internal gates already...seen a few on ebay

Well, the 530hp Scooby on the front page of Japanese Performance magazine this month has an internal wastegate.
