The Supercharged engine has lower compression. The N/A engine has higher compression.

It's standard procedure for almost every manufacturer to lower the compression ratio for any forced induction engines. Especially for the turbo applications, but as well as the SuperCharged units. Anywhere the customer has a reasonable expectation to mess with things themselves, Nissan will err on the side of safety.

Trust me or don't trust me. Not like I'll kill myself if you don't.

And for a note, I believe Butterbean was talking about me. Thanks Butterbean! I think you have a red Xterra now. [ThumbsUp]
