This kit delivers a significant level of performance (+15mph) through easy to install, electronic, engine, exhaust, and pump enhancements. Requires use of fresh premium octane pump fuel (91~93).
RIVA Performance Power Filter is installed. Kit replaces restrictive factory intake system delivering improved throttle response and top-speed.
RIVA Intake Manifold Uprade Kit is installed. Precision tapered billet sleeve directly replaces restrictive mesh element in intake manifold enabling engine to produce more horsepower through increased air flow and boost pressure (+1lb).
RIVA Free Flow Exhaust Kit is installed. Kit replaces restrictive sound suppression system located between water box and hull exit reducing backpressure and engine operating temperatures.
RIVA Power Cooler Kit is installed. Power Cooler is dramatically more efficient than original intercooler system delivering an increase of 18 peak horsepower with exit temperatures averaging 50°F cooler than stock. Features large, unrestricted core that exhibits minimal pressure loss compared to stock intercooler and integrated blow-off valve mount that will accept recommended RIVA/HKS Blow-Off Valve (sold separately). Blow-off Valve relieves unwanted pressure during off-throttle operation reducing supercharger clutch wear and eliminating heat soak in discharge tube.
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 Valve Retainer Upgrade Kit is installed. Kit increases the reliability of your engine by reducing the possibility of valve float at high rpm.
RIVA Pro-Series Engine Cooling Upgrade Kit is installed. Kit delivers dramatically improved cooling efficiency to engine and oil cooler for increased performance & reliability. Greatly enhances water flow & pressure by replacing restrictive OEM pump strainer & water fittings with high-flow billet components and superior routing.
Solas Concord Impeller is installed. New design incorporates a large blade area and superior hub design that deliver increased acceleration and top speed. Billet nose cone included.
RIVA Performance Ride Plate is installed. Our ride plate increases top speed and significantly enhances handling characteristics.
