this is boomer.....
1) jonas isnt faster than i am
2) rx7's are not good first cars
3) na rx7's will never compare to a stock s13 for drifting
4) to build a t2 drift car, and you manage to find one w/ a solid stock motor you will need:
intake, full 3" turbo back exhaust, fuel cut defender, 720cc secondaries, walbro 255lph or rewired 3rd gen fuel pump, rear toe eliminators, coilovers, and strut bars

also, like everyone said, 13b's lack the torque needed in stock trim, so basically you have to compensate by entering drifts higher in the rpm's.

if anyone has anymore specific questions, etc go ahead and get ahold of me........
