Let's talk packaging.

People say "remote turbo" but in my humble opinion that's a last ditch resort - probably impossible unless you're running a dry sump due to the turbo oil drain issue. Turbos need gravity to let oil flow back to the pan!! Some people have suggested an electric oil pump to scavenge the oil return line, but I wouldn't recommend it. The moment that electric pump fails, your turbo is going to be cooked.

So where in the engine bay can the turbo go? There's definitely a place for an FMIC in the bumper (this car's bumper is huge).

I was looking at the space next to the exhaust manifolds but there is not much room there. Maybe room for a T25. You'd need at least a 50 trim T3 to make 450 SAE hp without turbo inefficiency heating up your IAT.

The other alternative I thought of was to use a large single turbo (Holset HY35 or Garrett T72) and put it in front and to the side of the engine.

Does anyone else have any more ideas about where the turbo could go?
