Hp rating and effeciency

[CopGn]

I am looking to make 550 hp at the crank or 500 at the rear wheels. I figure any more and I risk the bottom end. I also don't want to run high boost or max out the turbo. So my question which turbo will let me make the hp I want between 20 to 24 pounds at around 75% to 80% effiency? I was thinking the PT-67 turbo.

Ported & polished irons, ported lower intake and plenum, 3200 9", 3" single exhaust, 65lb injectors.

te45a, pt67, t70 all will get you there, but 75 to 83 lb inj will be needed also

You don't think I will have too much lag with the 70?
