GFB SR20DET Lightweight Underdrive Crank Pulley - GFB 2005
Suits RWD versions of the SR20DET, as found in the S13-S15 200SX/Silvia and 180SX. Along with the performance improvement, this pulley benefits high-revving engines by underdriving the water pump, which helps prevent cavitation and subsequent overheating when drifting/circuit driving.
Does NOT suit non-turbo SR20 engines or transverse mounted SR20DET.
This pulley does require shorter belts which are not supplied, as the required belts will differ between engines.
Typically S13-14 models use a 4-rib belt on the power steering, whilst S15 models use a 3-rib belt. This pulley will accommodate either, but it is worth checking your engine before sourcing belts.
For 4-rib power steering, you need:
1x 5PK900
2x 4PK860
For 3-rib power steering, you need:
1x 5PK900
1x 4PK860
1x 3PK845-860
