This kit is one of our most popular big bore kits. Why? Because it works and it smokes the competions big bores! With our y-pipe and Boyesen Rage Cages it makes 184-185 hp with well over 120 lb/ft of torque. Part of why it works so well is because we developed the motor's torque to be a real driving force behind the performance. That's 20 more lb/ft of torque over the stock motor! You can really feel it too! We have been abusing the competition all over North America with this kit. On the ice in New York, to the hills of Wisconsin, to the Mountains of British Columbia, we just keep turning heads. Send us your cylinders so we can carefully bore them, then extensively port them to our spec. Our 86mm forged dual ring pistons have proven to be very durable for many hard miles. Add our billet head for extra cooling and powerful combustion chambers. We also put the o-rings into the dome and machined the cylinder to accept the new style dome. This gives the inner o-ring better protection if you were to run extra timing or nitrous. For best results use with Boyesen Rage Cages, 880 Big Bore clutch kit and our performance Y-Pipe. Available for both low and high altitudes so please specify when ordering.
Stage 2 has even more drastic porting and gets you 3-4 extra ponies. Race gas recommended on stage 2 motors.
