Some people have been able to pull off 400whp on the dot with the smaller varient but it is more the exception than the rule.

I suggest looking into the 50 Trim T04E compressor wheel with a T3 turbine housing, these turbos are extremely affordable if you don't mind going with a simple top mount manifold setup.

The other suggestion I have is the GT3071R or GT3076R bottom mount varient, we have tuned a few up to 430-450 whp!!! on Stock bottom end and on a dyno dynamics (hear breaker dyno).

Just some other things to keep i mind.

Most important of all is TUNING TUNING TUNING.

Whether is be local tuner, or high quality wideband to fine tune the fuel map, and getting a solid timing map from a map builder, or doing some serious dyno time with a tuner who knows his EFI. Tuning makes all the difference in longevity, low end power and power band curve and peak power.
