    Hey guys,
    I am looking for some input for my turbo selection. It's a 97 4.6 4V with mild cleanup on the stock B heads with 03-04 Cams. The long block was built by MPR racing engines with Diamond pistons, Manley rods, stock cobra crank and around 9.75:1 compression. My target is 700+ RWHP on 93 and I'm also setup for E85. Looking for ideas on sizing and this is a street car with A/C, P/S, more than occasional driver.

    My setup is very similar to yours. With stock 01 cams and intake. I am running a Garrett GT4094R around 20# and its around 700+ at the wheel. I usually use 100 octane as mine is an occasional driver.

    Budget? Looks? borgwarner s366 works well priced right but not so great to look at.
