5+5 Cast Compressor Wheel — SPOOLOGIC SL-220-001

The SL-100-004 uses the SPOOLOGIC SL-220-001 5+5 cast aluminum compressor wheel in place of the original Early 1999 9-blade cast wheel. The five full-length main blades and five splitter blades provide a modest improvement in airflow efficiency and help reduce the compressor surge commonly associated with the original 9-blade design while retaining the stock operating character of the GTP38. This is a stock-replacement compressor configuration, not a performance-wheel upgrade.

• Inducer: 60mm
• Exducer: 80mm
• Blade Design: 5+5 — five full-length main blades and five splitter blades
• Material: Cast aluminum

Turbine Wheel & Internal Wastegate

The factory-style turbine wheel and internally wastegated GTP38 turbine housing are matched to the compressor wheel for stock-replacement operation. A factory-style wastegate actuator maintains the original boost-control configuration, with the wastegate beginning to open at approximately 22 PSI. This keeps the turbo operating within the intended factory range while maintaining familiar throttle response and drivability.

• Housing: Factory-style internally wastegated GTP38 turbine housing
• Wastegate: Factory-style actuator, begins opening at approximately 22 PSI
• Turbine Wheel: Factory-style configuration matched to the compressor and housing
• Boost Control: Factory-range operation; no OCR over-boost regulator or boost fooler required

Upgraded Internals — Standard

Every SPOOLOGIC turbocharger is assembled with updated internal components designed to improve durability, sealing, and rotating-assembly operation:

• Extreme-duty journal bearings — Premium bronze-alloy bearings machined to precise tolerances with updated oil-groove geometry to help maintain a stable oil film around the turbocharger shaft
• 360-degree thrust bearing — Provides greater thrust-bearing surface area than the factory-style 270-degree design to better support axial loads
• Step-gap seal rings — Help improve sealing and oil control at the compressor and turbine ends of the center housing rotating assembly
• High-speed VSR balancing — The rotating assembly is balanced at high speed to support smooth and consistent operation

1-Year Limited Warranty

Every SPOOLOGIC turbocharger is covered by a 1-Year Limited Warranty against defects in materials and workmanship from the date of purchase. Warranty coverage requires that the unit first be shipped back to SPOOLOGIC for inspection. If SPOOLOGIC determines the failure was caused by a defect in materials or workmanship, the turbocharger will be repaired or replaced at SPOOLOGIC’s discretion. Warranty does not cover damage from foreign object debris, oil starvation, contaminated oil, extended oil change intervals, over-boosting, over-fueling, operation beyond the turbocharger’s intended operating range, improper installation, use outside the listed fitment, cosmetic wear, coating discoloration, or normal heat cycling marks. Warranty does not cover labor, shipping, towing, downtime, or any other costs outside the turbocharger itself.
