    Hey guys. I'm needing some help with turbo selection.
    The engine:
    4.6L DOHC- B head, Manley I beams, Diamond pistons, etc.

    I think I have narrowed my choices down to a GT4294R: a Garrett ball bearing turbo.

    I'm looking for 650rwhp on pump, 750-850 on C16.

    The compressor is basically a perfect fit, but I'm not too sure on the hot side. What A/R should I go with? Is a GT42 tubine going to be laggy? What about a GT40?

    Thanks

    Stock intake n/a a b-headed cobra will make max hp around 6200-6300.

    Shifting at around 6500.

    Turbo spool around 3500 if possible
