P-trim on a 16V motor would be a good size due to the greater air flow of the head. It would be real lazy and have a lot of lag on a 8V motor.

 

I went to a dyno session(dyno dynamics) this past weekend and there was a David Raines (Powerhaus) built 951 w/3.0 ltr that on the first pull made 493WHP. I believe it had a K29. The car looks awesome and is going to be raffled off for $100 a ticket for charity. The owners name is Joe Cervantes(SP?)??
I think David said his pulled 430WHP at low boost probably with tons of trq.

A larger wheel in a small housing is not doing anything to help the back pressure problem. Sure you may have faster exhaust velocities but there would be a lot less volume going through the housing due to the larger wheel. A displacement increase from 2.5 to 3.0 is going to cause an increase of roughly 16.7% more exhaust that needs to pass through the turbo. If there is already a delta pressure imbalance, this is going to make the problem worse. If the back pressure is too high, you may lose hp.
A good T04E wheel for this set up would be the 60.
