Good move OP. Sounds like a good path given your goals. Looking forward to hearing how they do, especially with the Cobb tune.

Depends how you use the car. For sustained running under high load the cooling system is almost always the weak point of any turbo car, especially getting heat out of the head on the exhaust side. Improving the cooling is a good idea to keep a margin of safety, I'd look at running water wetter or similar at a minimum (Porsche uses one in Cup cars, standard stuff for hard usage). If you just "sprint" with the car the head and block has enough thermal mass to avoid overheating for short period.

Yes, larger turbos increase lag unless you also significantly improve the technology, the housing isn't the issue. On the other hand these are not that much bigger, and he'll reduce the lag by pulling the cats from the exhaust and likely end up back very close to stock lag when he's done, I'd guess.

The turbos aren't really significantly going to increase peak torque, which is what makes the car a handful. He'll just hold that torque further towards redline. That said, self control and good judgement will be needed.
