Picking the right Turbo

Iím building a new motor and turbo for my SVT track car (road course), my motor is going to be a low compression (8.5 to 1) forged rods, pistons and billet main caps, along with a ported head over sized valves, and a ford racing intake manifold. The turbo manifold is a Milteck manifold converted to run a external weaistgate, I also have a 3Ē down pipe and a exhaust.
Iím looking to make about 300whp, I know the motor and that is over kill for that amount of power but I want the car to last. Typically on track Iím never lower then 3500 to 4000 rpm, so Iím looking to have the turbo start building power in the range. My wuestion is what turbo sould I go with a GT2876R with a turbine housing a/r of .86 or go to a bigger like a GT3071r with an a/r of .63.

The helmet has a special meaning for many drivers. How important is it to you? - It protects my head.

Do you have any special rituals when the helmet is concerned like many have? - I wipe it so that I can see better.
