Big bore Kits RZR XP 900
-Big bore = more horsepower
-All our kits are tested, proven, reliable and fast.
-96mm use your stock cylinder resized.
-98mm and 99mm are new billet cylinders.
**We recommend that all 98mm and 99mm big bores use Carrillo rods. We have seen too many of these break stock rods and send them through the cylinders.
All kits include:
*Two piston kits (pistonringsclips and pins)
*Big bore cylinder (95mm and 96mm require your cylinder as a core)
*Big bore top end gasket kit
96mm big bore kit: 935cc
Same as above but one more mm. This kit offers the most bang for your buck. We offer this in 9.0:1 compression for turbo or superchargers and 11.5:1 for pump gas.
98mm big bore kit: (pictured above) 975cc
This is where a big price jump takes place. The reason for this is you will need to use an aftermarket billet big bore cylinder. We tested many and sell what performs reliably. 98mm seems to be the magic number for a turbo car. We offer this kit with CP 8.5:1 11.0:1 and 13.0:1.
99mm big bore kit: 995cc
This is as big as it gets. We offer this cylinder with 9.0:1 JE 12.0:1. This cylinder is closed deck which makes it very strong. Not recommended for turbo engines running high boost due to thin center walls. **Core charge: For 95mm and 96mm big bore cylinders there is a core charge. For 98mm and 99mm big bores there is no core charge since they are new billet cylinders. We need you stock cylinder as a core to make the next customer a big bore cylinder. You have the option to pay the core charge first and we will send your cylinder or to send us your cylinder and when we receive it we will ship your Big bore cylinder. We refund core charges 100% when we receive your useable core cylinder within 60 days.
