How to do an external wastegate on a internally wastegated 16G?

[Spoolio]

is there some kind of conversion?, or a kit that i can put an external wastegate on my 16G instead of this internal crap?

There are a couple of options, the most popular is to have the exhaust manifold modified to bolt on a wastegate such as this:http://www.dsmtuners.com/forums/showthread.php?t=220891&highlight=manifold+wastegate. Then you need weld the flapper shut on the turbo.

Or you could get an o2 housing for this purpose and remove the flapper from the turbo:http://rnrracing.com/ccp5/media/images/product_detail/02ewg.jpg

Get a cast or tubular manifold that has a flange for a wastegate already built into it.(http://us.st11.yimg.com/store1.yimg.com/I/machv_1889_103183922). The wastegate will be mounted there. Replace the stock O2 housing with a housing made for an external wastegate. Have the internal wastegate welded shut.
