Pnp what?!? Turbo? Head? In/ex manifold?

I don't think there are any down sides, unless u mess up,

I have same set up a u pretty much, I have my IM and heads in/ex that are Pnp, I'd if u can to Pnp the turbo with the 90 inlet and all, I mean u can but probably alot harder.

Couldn't tell u if it made a difference cuz engine is not running...yet. But I have pics if u want, nothing special tho. Even then I probably wouldn't know because totally new setup.

There is a great thread in the build section about heads and headwork (FujiK is the main contributor).
