Skunk2 Racing Tuner Stage 4 Camshafts

Skunk2's Tuner Stage 4 camshafts are designed as a performance upgrade to highly modified vehicles running the D15/ D16 VTEC engines. They will outperform other Skunk2 Tuner offerings, which makes them a great match for max effort NA and Turbo engine builds! Tuner Stage 4's require a simple valve spring and retainer upgrade due to the additional lift, duration, and increased rpm range. These cams also incorporate Skunk2's cutting-edge FAST RAMP and AMAX features, which are responsible for increasing overall performance, producing unmatched response from idle to redline. You can expect optimized mid-range and top-end horsepower/torque with peak power moved up the rpm band, producing a seamless VTEC crossover! FAST RAMP is the same technology used in Formula One racing, where seat timing is reduced, which results in additional cylinder pressure and more torque but without compromising valve-train longevity. AMAX—a Skunk2 design, simply maximizes area under the lift curve without compromising reliability or valve-train stability. Skunk2 Racing's profiles feature more duration than competitors' at lifts above 1mm, resulting in greater efficiency and power.

Enginetech Rebuilders Valves

For about the same cost of reclaiming valves, you can install brand new Enginetech Rebuilders valves. The purpose of these patented Enginetech Rebuilders valves is to help simplify engine rebuilding by salvaging worn cylinder heads and reducing the need for expensive parts like valve seats and springs. Designed with oversized heads and stems, and a lowered keeper groove, these specialized valves create a more efficient and cost-effective rebuild process. The Enginetech one-piece intake valves are made from HNV-3 high alloy valve steel (often used for exhaust valves). All of the valve stems are either triple chrome plated or gas nitrided. Enginetech even goes a step further and hardens every valve tip to 50HRC minimum. The Enginetech exhaust valves are also a one-piece design. All Rebuilder's exhaust valves are made from EV-8 or EV-12 stainless steel. Again, like their intake valves, all stems are triple chrome plated or gas nitrided. Wafer tips, hardened to 50RHc, are inertia welded to every tip. Select the valves you need for your engine rebuild.

Enginetech Engine Crankshaft Thrust Washers

Enginetech offers engine crankshaft thrust washers for a wide range of applications. These precision-engineered, wearable components are designed to control crankshaft end-float (axial forward/backward movement) in engines. They protect expensive crankshafts and engine blocks from damage by providing a dedicated wear surface, meeting or exceeding OE specifications. Order the washers recommended for your vehicle. Key features and functions: * Prevent damage: These washers take the wear, preventing the crankshaft counterweights from striking the cylinder block, which can cause catastrophic engine failure * Control end-float: They manage the forward/backward movement caused by clutch operation in manual vehicles or torque converter loads in automatics * Maintain alignment: They ensure the crankshaft remains in the correct position for proper connecting rod alignment, preventing binding, jamming, or uneven piston wear * Material quality: Often manufactured from durable, high-quality bronze or bimetallic materials that can handle high-load, high-friction scenarios * Using Enginetech thrust washers ensures precise clearances, which is crucial for oil pressure retention and preventing crankshaft "walking"
