Picking a Turbo

[Simpler=Better]

I may be getting my hands on a second 617.952 driven vehicle for a project car. One car will become a decent w123, the other will be an almost-all-out performance car.

I'd like to stay variable vane (If it's cheap enough) what would you guys recommend for the performance car?

The DD will be getting my GT2056V, stealthy gauges, rack limiter removed. No performance mods beyond that.

If it all goes as planned(haha) the performance car will be getting the following:

Rack limiter removed
Torque control raised
25-30lbs boost
3" stack
1GPM/cylinder methanol&water
Lincoln-locked differential
Underdrive aluminum pulleys
No power steering
Electronic fan
On/off switch for the alternator

I want to show the local Cummins guys a thing or two....
