CP Pistons is one of the most trusted names in the industry, and for good reason. Their extensive shelf catalog provides the user with many of the options that you'd normally be resigned to going to a custom piston for. Their standard offering already includes Dual Pin Oilers - providing double the amount of oil to the wrist pin, radiused valve relifs, and the pin fitting final hone on the wrist pin bore. They even include an Accumulator Groove as a standard option. This provides a small pocket for the combustion gasses to collect after the first ring, reducing ring flutter and providing a better seal allowing more downward force on the piston A.K.A. - make more power. All pistons come balanced within one gram, include pin lock grooves and wrist pins at no additional charge.
Pauter X Beam Rods are a strong, high power rod option for this engine. They are relatively light for their strength class thanks to their X Beam contstruction. The X Beam design makes for great aerodynamic efficiency in the crank case, slightly reducing drag of rotating parts. Pauter is an excellent rod option for power levels up to 250hp per rod. If you have bigger plans than 1000hp for your engine, please contact us to explore other rod options.
