HOW IS YOUR TIMING BELT?
OEM timing belts were never intended for use with tuned engines!
Replacing worn or stretched timing belt might just save your engine!
COMPARISON : TOMEI vs OEM
TOMEI TIMING BELT FEATURES
The Nissan and Subaru belts have matching marks similar to those on the OEM belts, allowing the user to check the position of the belt in relation to the cam pulley and crank pulley correctly when installing the belt.

The VALC profile allows the valves to open faster and for longer. This translates to faster lift and increased area under the ‘lift curve’ (see fig. ①)
Unlike the valve opening, the VALC profile ensures that the valves close at a slower rate, helping to prevent common valve train related issues.
With a conventional direct-acting valve train, the maximum lift is usually determined by the size/diameter of the valve lifter. Selecting a high-lift camshaft without taking this into consideration often results in the camshaft lobes travelling beyond the surface of the valve lifter. This causes the lobe to make contact with the edge of the lifter, damaging both components over time. （see fig. ②）
