Description
RXT-X AS 260 /RXT IS 260 STAGE 2 KIT
This kit delivers a significant level of performance (+7mph on U.S. models) through easy to install, bolt-on engine, exhaust, and pump enhancements. No internal engine modifications are required. Requires use of fresh premium octane pump fuel (91~93).
RIVA Power Filter Kit is installed. Power Filter Kit dramatically increases air flow to your supercharger via a large 4″ diameter intake duct and oversized K&N filter element delivering greatly improved acceleration and top speed. Ducting is precision formed from a race proven composite that will not conduct heat to incoming air. Installs securely to supercharger via a tapered velocity stack, silicone coupler and stainless steel clamps. Includes pre-filter element.
RIVA Intake Manifold Upgrade Kit is installed. Removal of restrictive screen element from inside of intake manifold enables your engine to produce more horsepower through increased boost pressures (+1lb). Special o-ringed, billet block-off plug with integrated fitting for aftermarket boost pressure gauge fills opening left after removal of screen element.
RIVA Fuel Pressure Regulator Kit is installed. Kit provides precision control of fuel pressure to meet fuel requirements of modified engine. RIVA Stage 2 Kit requires a consistent fuel pressure of 65psi (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.
