You put a TTV6 in a car like that for cost/simplicity purposes. The fewer engine families a car has, the simpler it is to build. The simpler a car is to build, the cheaper you can build it. This is the same reason that turbo 4 cylinders are replacing V6s in midsize cars.

I never got to reply to this argument in the last ATS-V thread that we bumped heads in. The TTV6 might as well be a different engine family because the engine bay needs to be designed around the engine in the sense of packaging, cooling, etc - Three engine choices is three engine choices, packaging wise - having a modified subframe (if you even need to move the engine mounting points) would probably be easier than packaging a twin turbo.
Once again I will clarify - I don't care if it is LT1 or LF3 (or w/e the TT is) but I'm going to guess it would be over 425hp. Why? The Camaro weighs ~400 lbs more with equivalent power and has 4 piston calipers. Maybe this isn't the case but we all know how well GM...."budgets" so why throw 6 piston calipers on a car that doesn't "need" them?
