GTR 215 15-12 STAGE 1 KIT

This kit delivers a significant level of performance (+5mph on U.S. models) through easy to install, bolt-on engine, exhaust, and pump enhancements. Requires use of fresh premium octane pump fuel (91~93).
RIVA Power Filter Kit is installed. Power Filter Kit draws cold air from outside your engine compartment delivering awesome performance and eliminating power-robbing heat intake. Air intake is relocated forward away from hot engine delivering cold, fresh air to engine via large 4” smooth-bore ducting that is attached to supercharger with unique velocity stack and sturdy billet clamps.
RIVA Catch Can/Engine Breather Upgrade Kit is installed. Easy to install catch can/oil breather eliminates power-robbing crankcase fumes and oil vapor from your engine’s air intake. Increases horsepower by removing the engine’s requirement to burn relatively non-combustible oil. Also improves intercooler efficiency by preventing the oil sludge coating that lowers thermal efficiency.
Sea-Doo X-model Supercharger is installed. Complete supercharger assembly easily delivers a significant increase in boost pressure and horsepower through increased blade area and larger interior volume.
RIVA Power Cooler Tube Upgrade Kit is installed. High strength aluminum tubes are shorter than original to minimize boost loss. Rigid aluminum will not swell under pressure like original soft rubber hoses providing improved throttle response & reliability. Includes integrated blow-off valve mount for improved reliability and performance. RIVA/HKS Blow-Off Valve (sold separately) eliminates unwanted pressure during off-throttle operation reducing supercharger clutch wear and eliminating heat soak in discharge tube.
RIVA ‘GEN-3’ Power Cooler is installed replacing original intercooler system. Power Cooler is dramatically more efficient than original intercooler system delivering an increase of 15 peak horsepower with exit temperatures averaging 50°F cooler than stock. Features large, unrestricted core that exhibits minimal pressure loss compared to stock intercooler.
RIVA Power Cooler Installation Kit is installed. Kit allows you to remove the smaller, inefficient stock 215 intercooler from the intake manifold and install our larger GEN-3 Power Cooler remotely in your craft resulting in better all around performance.
RIVA Fuel Pressure Regulator Kit is installed. Kit provides precision control of fuel pressure to meet fuel requirements of modified engine. RIVA Stage 4 Kit requires a consistent fuel pressure of 58psi (static/non-rising rate). OEM fuel pressure varies between 48~58psi. Plugs directly into original fuel system with OEM connectors and features a large 3/8″ fuel return line. Includes integrated liquid-filled pressure gauge and billet Fuel Pressure Regulator Block-Off necessary for removal of stock fuel pressure regulator in fuel tank.
RIVA Free Flow Exhaust Kit is installed. Kit allows removal of restrictive sound suppression system located between waterbox and hull exit. Improves engine performance by reducing back pressure & restriction.
RIVA/ViPEC V88R3 Pro-Series ECU is installed. Our racing ECU provides huge increases in performance and matches the needs of your modified engine. Base maps are calibrated to provide optimum fuel delivery, ignition timing and rev limit to compliment the Riva Racing Performance Kits. OEM dash display, engine diagnostics & engine safety functions are retained. This ECU also provides “First In – First Out” data logging. This internal data logging function continuously records engine data, overwriting oldest data when the memory is full. This ECU is fully programmable, allowing the user to adjust or create new parameters. Includes input for optional Lamda sensor kit for data logging air/fuel ratios & tuning functions. ECU plugs directly into OEM wire harness and mounts directly in place of the stock ECU.

RIVA Thermostat Kit is installed. Kit reduces operating temperature of modified 4-TEC® engine by 30°F for maximum reliability and performance.
Solas ‘R’-Series Concord Impeller is a special performance impeller offered exclusively by RIVA and RIVA authorized dealers. This impeller is specifically pitched for our specifications using a pitch block to ensure accuracy. Billet impeller cone is included.
