Polaris Rzr Stage 3 Engine Kit
Bolt On 70-Horsepower on Pump
Gas for Your Polaris Ranger RZR
Lynden, WA (8/24/2009)
- 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 Muzzy Stainless Dual Exhaust
System. Coupled with the Kroyer motor kit, the
Muzzy 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)
With impressive dyno results, easy to use reliable
power and a proven track record, The Kroyer motor
kits from Holz are enough to make a die-hard turbo
guy sweat.
Each kit was designed and built for the ‘regular’
guy. While the Kroyer motor has proven to be very
competitive on the racetrack, it hasn’t
lost the simplicity and durability that you get
with a pump gas, natural aspirated motor. Holz
and Kroyer have addressed every variable so that
there is no guesswork involved. We’ve calibrated
the fuel, timing and clutching for you. Follow
the detailed instructions included in the kit;
forget the guesswork and experience hassle free
power from Kroyer Racing Engines and Holz Racing
