Holz/Kroyer Racing Engines Polaris Stage 3 Kit

Bolt On 70-Horsepower on Pump Gas for Your Polaris RZR 

Lynden, WA (August 19, 2009) Unlock the power potential of your Polaris RZR/S with the all-new Kroyer Racing Engines Motor packages offered by Holz Racing Products. Experience race proven performance and pump gas reliability with no loss of drivability.

The Kroyer Stage 3 motor kit just might be the most complete engine kit available for the Polaris RZR. Starting with the ported head that has been expertly machined on a 5 axis CNC and outfitted with oversize valves and springs – the head sits atop a Big-Bore Cylinder with matching 11:1 compression pistons. The cylinder also has been CNC bored and coated with Nickel Silicon Carbide cylinder coating (Nikasil). Complementing the ported head and larger valves is a billet CNC machined Hi-Lift/Duration Cam with stout chromoly push rods and hydraulic lifters. Fuel is fed through a 46mm bored throttle body and a billet aluminum intake manifold. Also included is a new adjustable PRV (oil pressure relief valve), which will help ensure that your new motor parts are bathed regularly in Joe Gibbs Racing oil. Topping it all off is a gasket kit, clutch kit, ECU ignition upgrade, break-in oil and filter, and new iridium spark plugs.

The Stage 2 kit is nearly identical to the Stage 3 kit, with the exception of its bore size. The Stage 2 kit utilizes the stock cylinder/bore and includes a pair of stock bore (80 mm) 11:1 pistons.

 Also available is the Muzzys Performance Stainless Dual Exhaust System. Coupled with the Kroyer motor kit, the Muzzys exhaust gained an additional 7 HP over the stock RZR-S exhaust, just cresting the 70hp mark for crank HP. (See Dyno chart for comparison)
