SOLID PIVOT 4G63 EVO1-9

VALVE TRAIN

Mitsubishi had chosen to use the lash adjuster (hydraulic system) for the 4G63 cylinder head for mass production efficiency, maintenance free and quieter operation. The best way to get more power from the 4G63 engine is to convert it to the solid system which is by far more superior in allowing running more aggressive camshaft profiles. The Solid conversion helps with more efficient opening and closing of the valves and therefore helps improve response throughout higher RPM ranges. This product uses internal shims to adjust the height. The kit includes 2.500 shims for each pivot (various shim sizes are available and sold seperately). Designed to be used in conjunction with other solid conversion upgrade products (as mentioned above in the notes) from Tomei Powered for the 4G63.

PRODUCT INFO

FEATURE / SPEC

 ■ Improved Response
With the especially designed cam profile characteristics, with the touch of the throttle you will realize the amazing response and improvements in efficiency of the best valve timing.

■ Designed for high end RPM use.
The solid conversion will eliminate the dullness experienced at high RPM when using the hydraulic adjustable type.

■ Special Camshafts and Valve Springs
The solid conversion will also require the appropriate solid type camshafts to be used with the solid pivots. Also since the solid camshafts are designed with higher cam lifts, our Tomei valve springs will also be required to provide the adequate clearance and appropriate spring rate (Sold separately).

■ All types of competition use..
With serious race competition where every second counts in Drag, Circuit Time Attack, one make race or GT events, a solid conversion is required to get that extra gain over your rivals.

■ For Monster Power Cars
The 270° and 280° solid type camshafts will utilize the full potential of the large size turbo units.
