SPOOLOGIC Stage 2 Performance Turbocharger

The SPOOLOGIC Stage 2 GT37 Conversion Turbocharger Package SL-100-042 is a performance upgrade for 2011-2014 Ford F-250 F-350 F-450 pickups with the 6.7L Powerstroke. It brings a higher-output GT37 configuration to the original GT32 application while retaining the factory exhaust connections, supporting approximately 650-700 rear-wheel horsepower with matched tuning, fueling, and supporting modifications.

⚠️ Custom tuning required before operation. Do not operate on the original factory calibration.

Tuning and Supporting Modifications

⚠️ Custom Tuning and Supporting Modifications: Custom tuning is required before operating the vehicle. Fuel delivery, intake airflow, charge-air capacity, and exhaust flow must be matched to the intended power level. Additional upgrades may be needed to achieve the listed power-support range; the turbocharger alone does not produce that output.

Supporting Modifications: Upgrade components as needed to support your intended power level.

• Larger injectors and fuel-system upgrades may be needed to reach the listed power range.
• Intake and intercooler upgrades may be needed to reach the listed power range.
• Adequate exhaust flow and leak-free up-pipes.
• Boost and exhaust-gas-temperature monitoring during setup and loaded operation.

SPOOLOGIC does not provide custom tuning services. Customers are responsible for arranging application-appropriate tuning with a qualified tuning provider.

Power Support

Approximately 650–700 rear-wheel horsepower with a properly matched build. This is total power-support capacity, not a promised horsepower increase. Actual output depends on engine condition, calibration, fuel delivery, and the complete vehicle combination.

GT37 Conversion

The SL-100-042 replaces the original GT32 turbo with a GT37 journal-bearing design. Its custom SPOOLOGIC turbine housing connects to the factory up-pipes and downpipe without replacement exhaust plumbing or fabrication. The included conversion pedestal provides internal oil feed and return passages, eliminating the external turbo oil-supply line. Reuse the original pedestal-to-engine-block bolts during installation.

Compressor Wheel

• Blade design: 7+7
• Compressor inducer: 65 mm
• Compressor exducer: 88 mm
• Extended tip: 90 mm
• Material: 5-axis CNC-machined billet aluminum

Turbine Shaft

• Turbine inducer: 72.5 mm
• Turbine exducer: 66 mm
• Turbine blade count: 10
• Material: High-nickel Inconel

Upgraded Internals

• Upgraded journal bearings
• 360° thrust bearing
• Step-gap seal rings

High-Speed VSR Balancing

The rotating assembly is high-speed VSR balanced before shipment for smooth, consistent operation.

VGT Control System

The turbocharger is assembled with a new VGT control solenoid and a factory-style 2017-2019 vane cage and unison-ring assembly. VGT-based exhaust-brake operation is supported, but actual exhaust-brake behavior depends on the strategy programmed by the custom-tune provider.

Coatings and Finish Options

The turbine housing, center-section exterior, and pedestal are ceramic coated to help manage radiant heat and resist oxidation. Heat reduction varies with operating conditions. The finish options below apply only to the compressor housing.

• Raw: Natural aluminum with no coating
• Red: Red powder-coated finish
• Black: Black powder-coated finish

Every SPOOLOGIC turbocharger carries a one-year limited warranty against defects in materials and workmanship from the original purchase date. Coverage applies to the original purchaser with dated proof of purchase. Contact SPOOLOGIC for return authorization before shipping the turbocharger for inspection. If inspection confirms a covered defect, SPOOLOGIC will repair or replace the turbocharger at its discretion. Coverage excludes damage caused by foreign-object debris, oil starvation, contaminated or restricted oil supply or drainage, extended oil-change intervals, overboosting, overspeed, overfueling, excessive exhaust temperatures, improper installation or startup, improper tuning or repairs, or operation outside the listed application or intended operating range. Normal cosmetic wear, coating discoloration, and heat-cycling marks are not covered. Customers pay shipping to SPOOLOGIC and return shipping, whether the claim is approved or denied.
