Are ALL GM Engines ok for all GM Model Cars?

If I was building a supercar, I'd use a variable inlet turbo. You can size it big, but it will spool similar to a smaller turbo. That's one of the I said that on a well dialed in setup, there is virtually no lag.

But no matter what kind of turbo you are running on a street setup, it's not going to make boost at idle, and it's going to make very little boost at part-throttle. It's only spooling when the engine is under a load.
