Tomei Timing Belt for Toyota MR2 AW11 85-89 4AGE 4A-GZE 16V 4 Valve

Despite being a typical component of engines, not all OEM and aftermarket timing belts are made to be utilized on highly tuned turbopowered engines. Performance engines with aggressive camshafts, higher torque from the valve springs, intense heat conditions from the larger turbos, and other factors that cause high RPMs substantially impair the timing belt's durability.
