They are rated at 160HP at the flywheel but still lack the torque (like 111 or something close). I say becareful because they are much lighter than the 4th gen. I'd have to say that comparing a Civic Si w/ a 4th gen Lude Si would depend on the driver. Don't take them for granted though cause they can run mid 15's easily and most Prelude Si's run high 15's.
Just my opinion of course!
