Well, the 92 weighs a bit less., that helps a little bit, also the intake, exhaust add a good bit to his torque which is what helps VTEC pull harder, (Correct me if I'm wrong). Does he have the JDM Type-S engine, Usually comes with a redtop, cause that engine dynos @ 220 hp and with those mods easily comes close to 235-240hp which on a car that light would be reasonably fast. Even with the normal engine though, hes close to 220hp with his mods.

PS. I raced a 97+ lude vtec and kicked his ass, with my stock 92 Si, i think his was stock too, of course then my EGR system wasnt working so I was adding a good 10-15 hp or so. ~ 175hp vs 200hp.
