Will the 44's be able to keep the boost down?

I'd recommend a pair of precision pw46 gates and a single turbosmart raceport bov.

44's would be more than adequate. But the Precision 46's are keenly priced.

That said, Turbosmart do some nice 40mm's now that are pretty cheap and fairly compact.

Depends on how low you want to go with boost.

So 44-46mm gates and one big or two smaller BOV's will do the job and keep the boost in check.

Depends on budget twin tial 38-44mm or precision 46mm and two TiAL bovs would do the trick just fine just as said depends on how low you want to keep boost. Lower numbers bigger gates

JGS is a good brand also.

Twin 44's will be plenty.

Twin 44s are plenty. Wastegate placement will play a huge part it making the most out of them. With optimal placement, 38s would probably even do the job.

Ive used Tial 38's on a twin 6765 427 and controlled down to 12psi just fine. Need very good placement though. Also used one 50mm BoV.

Huronspeed BOVs are good and don't cost a fortune! I know a lot of guys using their BOVs. I have two 46mm precision gates and two 50mm huronspeed BOVs.
