External Wastegate with td04 turbo...is this possible? *UPDATED*

Hey guys,

As most of you know I am running a td04-15g turbo on my b7, since my buddy is parting out his turbo setup. I am thinking to get his external wastegate. Since, my turbo has an internal wastegate. Will his tial 38mm wastegate work for my turbo? Is this gonna be an expensive conversion? Or is this just a straight bolt on to my turbo? Thanks gain.

then buy it and sit on it untill you can really use it. I've done that with plenty of parts (and cars..) and it works out.
so you saying that... get the wastegate now, but dont use it on my setup right now? or at least wait till i get a bigger and better setup like on a t3/t4 turbo at least?


heres mine, hopes this helps ya out
i am guessing you have a z6 or y8 engine? and are you also running a td04-15g turbo or is that a bit bigger? how big of a hole did you drill on your manifold? and with your wastegate facing forward...is it pretty hard changing the springs to turn up the boost? thanks for the pic btw, really appreciate it at least now i am have some idea on how to do it :).

Exactly, if it's that good of a deal don't let it go if you know you can use it later, or if you can make a few bucks if you decide not to use it.

is there any other alternatives/way that i can weld my external WG, rather than the one in the pic with the y8 engine? thanks.
yes.

You can weld it up front in the middle, where the screw hole is.
You can weld it of the left runner.
You can weld it on the internal WG port.
You can make a spacer between the manifold and the turbo, and weld the WG on that spacer
yes.
