hmm.

Then there's the block limitations...

anyone can claim the turbo is designed around a stock engine, but the fact of the matter is that no matter how strong a stock block may be, it's still a risk turbocharging (or supercharging) a car that was never designed for boost in the first place. Doing a built motor (aftermarket forged pistons and rods) goes a long way towards mitigating that risk.

Absolutely, positively correct. It's usually the pistons that go first.

If you keep the boost reasonable low (under 5 psi) you can probably get away with it on most any motor. However, everyone I know once they taste the power; the first thing they want to do is up the boost. Then what?? Ring lands usually and new pistons immediately after usually followed by a few rods.

Yeah they have kits for the stock motor but you would NEVER want to even aproach the 10 psi barrier with 11-1 compression unless you are running meth
