YOur engine is a bad engine to turbo because its stock compressiong is 11.5:1 which is just way to high to add any sort of reliable boost to that.
Wrong. LE5 runs 10.4:1 CR from the factory.

Wiseco makes 8.8:1 forged pistons for the motor as well. You should be able to run up to 14psi on the stock motor... but I wouldn't run more than 10psi personally until getting the Wiseco pistons.

I like your dealer for telling you this, even if it's probably a bunch of fluff.

No, you don't.
