GFB Lightweight underdrive crank pulley for Nissan 200SX/Silvia/180SX S13–S15 SR20DET

Lightweight underdrive crank pulley for rear-wheel-drive SR20DET engine variants fitted to the S13–S15 200SX/Silvia and 180SX models. In addition to improving performance, the pulley is also suitable for high-revving engines, as it drives the water pump at lower speeds. This helps prevent cavitation and the resulting overheating during drifting or track driving.

Important: The pulley is not suitable for naturally aspirated SR20 engines or transversely mounted SR20DET engines.

Shorter belts are required for installation and are not included, as the correct belts vary depending on the engine.

On S13–S14 models, the power steering is usually fitted with a 4-rib belt, while S15 models use a 3-rib belt. The pulley allows both versions to be used, but check the version fitted to your engine before purchasing the belts.
