I've never seen a built LS making over 160 at the wheels.

A decently built (like my friend's) should start at 160 at the wheels.

You start adding to either motor from there, exponentially, and tell me how exactly it's even? I've owned an LS and now I've got the R. A decent LS/VTEC should be on par or better than my engine stock.

Make an LS do that, please.
