What can i expext from this T04b?? (pics)

I bought this stock upgrade a while back , it's just a compressor upgrade, with stock exhaust turbine. what can i expect out of it HP wise, with a ported wastegate, full 3" dp & exhuast, fmIC and fuel upgrades?

thanks.

I doubt anyone can give you a clue without the specs.

Agreed. Very hard to make a guess without the specs on it, and without knowing how much boost on what type of engine (stock/streetport/bridgeport/etc).

On a streetported engine however, running say 18 psi maybe 320-380 rwhp? This is a REALLY wild estimation though.

What about a T04B compressor housing, compressor wheel and turbine wheel(p-trim) with a 360º thrust bearing?

Oh and while I'm at it, I believe I read that you can port the wastegate a little more than the size of the flapper. Is that true or no? Thanks(Oh and I did search, there are 5 million posts on "ported wastegate" port wastegate" "how-to port wastegate" etc etc etc).
