Speedwerx Turbo Kit // 2025-2026 Arctic Cat ZR / Riot 858 C-TEC2 

Trail Turbo Kits are in the werx! Stay tuned for more info- the projected release date is Jan 1st. We are safely seeing over 215 HP at 8300-8500 RPM with 5 psi of boost in summertime conditions!

Our Turbo Kit comes complete and ready to install without any major chassis modifications. Comes with instructions and step by step video instructions will be available on our website and YouTube page as well. Kit utilizes stock coolant and oil lines to feed turbo. Fueling is controlled from a re-flashed ECU and standalone G3 controller box that controls the secondary fuel injectors. As of now we are the only aftermarket company running 4 injectors, but both Polaris and Ski-doo run them on their turbo sleds direct from the factory. This provides better throttle response, better acceleration, and better power. Our aluminum charge box comes pre-assembled with a high flow secondary air inlet valve to for improved throttle response and deep snow drivability. We also send a hood upgrade with the kit to remove most of the internal stock hood intake parts. Last but not least, we include our complete clutch kit with our adjustable weights pre-set to our baseline specs.
