Spoken as somebody who truly has never had the pleasurable experience of driving a VNT equipped car.

A VNT is a far more noticeable change in performance than 20hp from the rack limiter. The rack adjustment and torque capsule will have no significant effect on low end torque since power is limited by the same air availability and the stock turbo's poor response time.

The graph curves tell all. The only difference between the two graphs is time and a GT2256V instead of a K26. There is no difference in fueling, only air.


Which curves would you rather have?

JDmills wants low end torque over anything else so clearly a VNT should be priority, if not a supercharger.
The GTA2056V from a Jeep Liberty or M90 supercharger from a Buick or Ford would be about ideal for his needs.

EDIT: Here is the video I was talking about earlier. Right is exhaust pressure, left is boost. http://www.youtube.com/watch?v=eM7SNOc3nMY Its interesting to watch the exhaust gauge, you can see how the vanes open and close to control boost through exhaust velocity (exhaust pressure). Try doing that with your T3!
