Nissan Skyline, RB20DET/RB25DET/RB26DETT
Belt strength has been optimized and designed to allow stable belt tension even when heat expansion occurs in the engine.
Previous timing belt manufacturing techniques have involved with applying pressure from the outside to the teeth. This applies tension to teeth making them weaker. By forming a mould with the correct shape of teeth to begin with, it allows the teeth shape to be formed without compromising belt strength and can decrease the belt skipping at high torque engine.
Optimized belt strength for each engine application makes the Fine Tune Timing Belt ideal for use with Tomei Slide Cam-Pulleys for high power/high RPM engine.
