Yes you are right except I don't think the DI V6 has VVT. The two Cadillac options are:
3.6L V6 VVT: 263 hp at 6200 rpm and 253 lb-ft of torque at 3100 rpm
3.6L Direct Injection V6: 304 hp at 6400 rpm and 273 lb-ft of torque at 5200 rpm
So I guess it is more of a question when do you want the powerband to kick in. But if we are adding a turbo to these cars I would say go with the DI V6. I would be nice if they could combine both technologies like they did on the 2.0. Imagine a 3.6L SIDI VVT? Then add a twin turbo setup to that? I think the solstice would be all over the place.
As for the weight question everyone worries about. Remember we can always throw the battery in the trunk like GM does on the other models for weight solution. And I'm sure adding extra suspension in the rear to increase weight and stability could help balance it out. I think this is a very viable solution.
The only thing that comes to mind was when Chevrolet was looking at making a Kappa car they where planning on going V6. And they found that a V6 VVT left the valve cover to high to fit under the hood (not quite sure if that was true or not, or if they meant DOHC was too high as well since VVT doesn't increase the valve cover height much at all if any). But hey the way I see it is if we can shoe horn a V8 under the hood I'm sure a V6 option would not be that hard to engineer. Would probably be even easier to engineer than balancing a V8. And I can easily imagine a V6 SIDI VVT Turbo motor putting out 400 hp. (LS3 replacement solution anyone?)
