One of the biggest weak points in 1.8T engines is the screw connection of the belt pulley to the crankshaft. This weak point was already known in the G60 engine and led to major engine damage, not only in tuned engines, when the guide groove on the crankshaft sheared off. Our High Torque Kit reinforces the belt drive on the crankshaft with an additional guide pin made of high-strength quality steel. Included in the kit: Pulley with pre-drilled hole for guide pin Special drill bit Reamer 1 stainless steel guide pin We recommend pinning for all 1.8T engines with increased power. Especially if reinforced valve springs are installed, as the higher forces in the valve drive result in even greater stress on the belt drive! The High Torque Kit offers the great advantage that the engine does not have to be removed.
