Reinforced Gates Racing RPM Timing Belt, T199RB

On a high-output engine, the timing belt has no margin for error: it synchronizes valve opening with piston travel, and a failure on an interference engine ends in a complete top-end rebuild. This is the home turf of the Gates Racing RPM range (Racing, Performance, Muscle): timing belts designed to keep up with high-performance engines.

What sets Gates RPM construction apart

• HNBR composite: HNBR rubber (HSN compound) resists heat and degradation from engine fluids (oil, fuel) far better than standard belt rubber.
• Aramid cords: roughly 5 times stronger than steel at equal weight, they absorb the torque spikes generated by a forced induction engine without stretching or losing timing.
• Nylon-reinforced toothed fabric: reinforces the junction between the teeth and the belt body, the point that wears first under repeated shocks (downshifts, rapid rev changes).

Technical specifications of part number T199RB

163 teeth, 8 mm pitch, 27 mm width, 1304 mm effective length: verify these dimensions carefully against your original timing system before ordering.

Compatibility

This part fits demanding engines such as the Toyota Celica (ST200), as well as the Toyota Celica (ST18) and Toyota Carina E. In total, 14 engines are listed as compatible with this belt.

Like the clutch or reinforced engine mounts, this is a part to plan for as soon as you increase engine output, not after the fact. Gates is an original equipment supplier for most major automakers: the RPM range applies this same industrial expertise to the specific demands of engine tuning.

Warning: do not rely on the model name alone. Displacement, engine code and model year can change the original fitment on the same vehicle: check these points before ordering to avoid any returns. Also note that some belts are black! This is a Gates design choice.
