IMO I think you'd get your ass handed to you

All cars lose horsepower from the crank to the wheels. When they sell a car to you, they tell you about the crank HP. From there, you have all sorts of powerlosses in the form of transmission friction, wheel weight, bering friction, etc.

Hondas on average lose somthing like 13% of their HP through these inefficiencies. While the Sentra SE-R looks to be losing nearly 20% if we're to believe this magazine, the engine also puts down 185lb-ft, which is really, really gonna tear up the poor little B16 you have in your car.

Though, since he DOESN'T has a manual, he can't have the 175 HP engine. The 175 comes in the V-Spec. He must have the regular SE-R, which while it only has 165hp/175lb-ft, will still put some decent power out...

All in all, if would be a friendly race, I'd say "heh, do as you will", but if you think he'll start slandering you and other BS, don't do it. I think you would honestly have a slim chance at winning.
