Polaris RZR
"Second Wind" Buildup Project
Project Overview:
Our Polaris RZR has served us well over the last two years,
but with some new products on the market, I decided that it was time to take
it to the next level. You can check out the first stage of our RZR buildup
here.
Our goal is to add some reliable horsepower, a killer audio
setup, a new roll cage, seats some new long travel shocks and a few other
goodies. We plan to have it all together and ready for the Dune Tour over
Halloween in Glamis.
Engine Performance:
Holz Racing Products has teamed up with Kroyer Racing Engines and built
the ultimate in big bore power for the Polaris RZR.
Holz/Kroyer Stage III Polaris RZR Engine Kit
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. I
already have a
Muzzys dual
exhaust, so with the new engine, it
should fly!

Audio:
My wife drives the RZR around
quite a bit, and she likes her tunes. Not that I don't, but I figured
that I would surprise her with something that would knock her socks off.
I didn't want a radio or Sirius, just an iPod input with some great speakers
and a nice amp with a factory look.
For me, there is only one
choice when it comes to audio for your UTV and that is
SSV Works. I have experienced their
system first-hand and it will blow your socks off. And they do such a
great job making the speaker pods look like they are from the factory.
SSV Works custom molded kick panels designed for 6x9"
speakers and bolt into the upper foot well away from your feet. They are
100% fiberglass for the best sound quality and bass response. They are
finished in a black texture coat to match Polaris textures and can be custom
painted to match your color scheme. - Includes stainless mounting hardware
and step-by-step installation instructions.
 SSV
Works custom molded sub enclosure is designed for a 10" subwoofer and bolts
into the under dash area clear of knees and feet. NO CUTTING REQUIRED, the
box simply bolts in and provides the proper airspace required for a 10"
woofer. They are 100% fiberglass for the best sound quality and bass
response.
EFX 4ch 800watt amp for those looking for clean, powerful
and
reliable power to your system. Ideal for 4 speakers, 2 speakers
and a woofer or bridged to 4 speakers and a woofer.

Roll Cage and
Bumper:
The roll cage I have is fine,
but I like the looks and the added safety of a cage that goes all the way
back around the rear and ties in with the a-arm pivot points. I also wanted
to use 1 1/2" chromoly to increase strength and lighten things up a bit. It
costs more than mild steel, but I think the extra cost is worth it.
Xtreme Machine and
Fabrication turned down some of there RZR cage ends to 1 1/2" for me and
Roggy Enterprises in Placerville, CA is building a custom cage.

A-Pillar Brace:
With this A-Pillar Brace you can now finish completely
reinforcing your RZR or RZR S chassis. This brace uses one factory hole and
the chassis to locate itself. There is some drilling required. The Racer
Tech A-Pillar Brace is a perfect addition to our Front Cage Mounts or our
Rigid Mount Front Bumper. All pieces are design to work together as one,
providing strength the factory could have only dreamed of. These A-Pillar
braces also double as a great mud shield to save you a lot of cleaning after
a dirty ride. All hardware and instructions are included.

Shocks:
I wanted to try to get things
fine-tuned more than I have been able to get my current shocks. Seems
like things were too soft in the g-outs and real stiff in the light chop.
Lots of new shocks are out there for long travel shocks, so I figured it was
time to try another route.

Dune Tires and
Wheels:
With the additional power I
am going to have from the Holz/Kroyer Stage III Kit, I want to make sure
that the paddle tires I have are not only lightweight, but also have enough
hookup.
T-9 Pro Mod wheel is significantly lighter than its
competition, reducing unsprung weight and rotating mass for noticeable
performance gains. The T-9 features a polished finish, a double-rolled lip
for excellent durability and ease of tire mounting, rugged yet lightweight
.190 wall construction.
The Dune Star lineup is the 26x9-12 front size, which
perfectly complements the proven 26x10-12 rear. Nothing hooks up harder than
the rear Dune Star, which features highly aggressive, reinforced, dual-depth
paddles for unmatched straight-line acceleration. The new front Dune Star
provides light, accurate steering, and like the rear model, uses a
super-flexible carcass for a superb ride.

HID Conversion:
Charging capacity always
seems to be an issue with all UTVs and one of the biggest power draws are
the factory halogen headlights. Lots of HID conversions are available that
will convert the halogen lights to HIDs. There are two advantages to
this:
-
Lower power draw.
-
Much more light output.
For our project, we chose to
work with Side x Side Customs.
35W Slim Ballasts and 6000K Bulbs in a
waterproof package makes this kit hard to beat.

Large Capacity
Battery:
The factory battery is a bit
on the light side, especially if you want to run any audio with the engine
off. Time to look at a better battery and a mount to hold it in place.
I found what I was looking
for at All Terrain Research. Their kit includes everything you need to
cleanly install a Odyssey PC925 battery in your Polaris RZR. The kit
features a Billet CNC Machined tie down that features a foam pad on the back
side so that the battery is firmly clamped down. The kit features all
stainless steel hardware and brass terminal spacers. Not to leave anything
out, ATR also includes a battery Tender ® harness.
