The VGT we have itself isnt perfected yet!. Have people noticed car looses power slightly/intermittently when driving continuously for 3-4 hours or more?. This is a result of not managing heating issues/pressures on or VGT turbo unit in the first place. This coupled with car having to pass emissions norms, complexities in tuning right, production, Economies of scale, PUNY 1248cc engine and a plethora of things a company needs to consider. Its not going to happen. Like said above if you want to try this as a project and keep the car strictly on the tracks/offroads, then you are welcome. How I know this, personal experience, wore out my stock VGT and had it replaced under warranty.(No clue if I wore it out or I was unlucky to receive a defective turbo) But, gained a ton of info on this.
