In order to make cam clearance maintenance-free and quieter operation sound, the hydraulic lash adjuster was adopted for the SR20 engine. However when aiming at higher RPM ranges and for higher horsepower output from engine modifications, it is important to improve the reliability of head system parts and to make valve drive train set correctly for the suited cam profile. So it is necessary to eliminate the use of the hydraulic lash adjusters. We have adopted the solid pivot system to enable adequate cam clearance adjustments while keeping total height of pivot of each cylinder fixed. Therefore it is possible to build a more precise head system in a shorter time compare to the other conventional methods. Improvements in the reliability and lower pricing were made possible at the same time by having reduced the number of parts required.
The Tomei Bery Rings are made from Beryllium alloy. This alloy helps increase the durability of the valve seat, has minimal wear resistance and increases effective heat dissipation for the valves. This material helps extract the heat from the valves as the cylinder head has the ability to remove heat via the water lines. This then increases the life of the valves so the engine can cope with higher power outputs and higher stress loads to meet the current trends of todays motorsports environment.
The engine & transmission mounts utilize a higher strength formulation of rubber compound, called HD Rubber. Replacing your factory mounts with these will stabilize your powertrain and help eliminate that annoying chatter or knocking from old, broken mounts. The result is a more linear and direct engine feel during high revolutions, which translates to a more responsive power output in reference to throttle position. Used in professional motorsports across the world, beware of imitators and make sure to get the original Cusco mounts.
These bolt-on in the factory locations and some applications may require to reuse factory hardware. A must-have for those performing an engine swap.
