a friend of mine and i were throwing some ideas around for a good set up for the street mod autocross class. n/a wouldn'd be the best since u can't realy keep the revs up high like u can @ the track. torque tould be the ticket i think. i was thinkin ls w/ a supercharger. but my friend made a good suggestion. a b20 supercharged. has anyone built one of these engines? any feedback would be greatly appreciated.
