Need Help.!!!!
 

Ok. So after racing my stock ka24de 240 and winning a race i realized i need more power. What are these crank pullys???? that add horsepower. Where to buy. See with this series the car has to be stock but theres alot of people doing stuff. Is there anymods that will look stock but increase horsepower. Thanks to whoever replys.

are you talking about like autox or something...I suppose pulleys, cams, ecu, clutch/flywheel, lsd...thats all i can think that they wouldnt be able to see
