Have seen these ages ago - go to the 3rd picture down -

I think S60 maybe 740 Volvo and Miata's run them
The entry of the wastegate gases seems better than 300zx gases and the exhaust pipe connection is a whole lot tidier easier
Cant find any exhaust housings in our size - Miata is .45 which would spool lol

I'm open to abuse - good idea - crap idea - been there done that - anyone know of T25 or T28's Garretts with this design exhaust housing in .60

 

Borg warner efr turbos use those sort of gates....not cheap though. No bolton options for the zed.

 

TBH, probably only a change for changes sake. No reason not to run them. They will work fine....
Wastegate gas does not come out nice and straight or evenly like a poppet style valve. The gas exit angle is close to irrelevant when it just expands into a dump pipe.
