would this work?

what manifold are you going to use?

if it's an aftermarket manifold I'd get it with an external wastegate flange and try to find a turbo w/o an internal wastegate (or disconect the stock one and weld the flap shut.)... that way you don't have to worry about a crappy stock wastegate... or it running too much boost out of the box.

Porsche 944's had externally wastegated turbo's... I'm sure some other cars do too... I can't think of any others right now though...
