RB-series engines in the R32, R33, and R34 Skyline platforms place tremendous stress on the timing belt, especially when equipped with high-lift camshafts, stiffened valve springs, and upgraded turbo systems. The Tomei Kevlar Timing Belt (TB101A-NS05A) is a high-performance upgrade specifically engineered for RB26DETT, RB25DET, and RB20DET applications, delivering superior strength, heat resistance, and timing precision under extreme conditions.
Tomei constructed this belt using premium Aramid Kevlar fiber on the surface, high-temperature H-NB rubber, and a high-tensile glass cable core. This advanced composition provides exceptional resistance to stretching, cracking, and failure even at high RPM and sustained boost levels. The result is rock-solid cam timing that protects your engine from catastrophic damage while maintaining consistent valve timing for optimal power delivery and efficiency across the entire RPM range.
At Terra Firma Automotive, we supply this genuine Tomei Kevlar Timing Belt as the trusted choice for RB engine builders who refuse to compromise on reliability. Whether you’re building a street machine, track car, or drag setup, this belt gives you the confidence to push your RB26, RB25, or RB20 to higher power levels and rev limits without worrying about timing belt failure. It is the ultimate upgrade for anyone serious about performance and long-term engine durability in their Skyline.
