So far, Campro have not proven itself to be popular within the modding circuit (other than within those fanatical Gen2 people who even go as far to claim their Gen2 beats Skylines and Evos on the street), and there must be a reason to it.

First thing is, all Japanese cars (integra, evo... yada yada) have a speed cut at 180 kmph. Waja does not have it. THerefore you just need to push to 190 and you'll win. I assume your "race" is done on the highway, fifth gear, fighting for top speed. Take the evo 7 and waja down to sepang, let some good driver drive both cars, and then the real results will show.
