hey, I just bought a brand new 05 busa and was wondering whats the best big bore kit out there along with a stroked crank company?. Also, is it comlicated to install the bore kit? I would really like to make the bottom end of the engine bullet proof...forged pistons, rods and crank. I would like to get the biggest displacement out of the motor so any help would be great. Also would i need to clearance the block for the stroke? Any websites or input from you guys would be great.....Thanks
