Also from what I have been hearing.. DSM-P is not making many wise business decisions... and may soon be out of business (again)... so what are you going to do for customer support at that point?
What? The DSM Shop make bad business decisions, I think I'm in shock.

I don't believe a single word you're saying. I know, a new name for the shop will fix all those problems.
Back on topic: This turbo is completely bolt on. Whether or not they provide the lazy people with a custon adapter for the downpipe. Whether you like it or not for a big turbo an external gate is necessary. So with a turbo of this size you would've been making custom pipes anyways to get the external to fit. In fact in this case it's even easier because they provided you with a PERFECT place to mount your external, all you have to do is decide how you wanna route the outlet of the wastegate.
Simply because you are lazy you cannot claim that something is not necessary. When you're flowing a lot of air you need a large opening for the wastegate (along with a strong spring) to be able to properly control the boost. Now, if your turbo isn't flowing a lot of air (at least not as much as your supplier is telling you it will) then you won't need that large of an opening or that strong of a spring. In that case you MIGHT be able to get away with an internal gate.
Don't come bitching to us when you free up some restrictions in your setup and turn up the boost only to find the boost spiking to all hell and blowing your pretty little headgasket. Do a little research on your own about turbos and boost control and then come back here and tell us if an external is necessary for this large a turbo.
