DieselSite Journal Bearing 66mm Wicked Turbo 99.5-03 Ford 7.3L Powerstroke
Transform the performance of your Ford 7.3L Powerstroke with this DieselSite fully-rebuildable drop-in turbocharger, designed to replace the stock GTP38. Take your pick of either 3" inlet or the massive 4" ported inlet (with 4" custom boot). This advanced turbocharger features a larger Wicked Wheel 2 billet compressor wheel with a 66mm inducer and 94mm exducer, coupled with a 1.0 A/R turbine housing. These components work together to significantly increase airflow, reduce exhaust gas temperatures (EGTs), and enhance overall engine performance.
The turbocharger's durable construction includes a journal bearing support and a 360° thrust washer, allowing it to handle higher boost levels while extending its lifespan. The superior CNC-machined wastegate ensures no leakage of drive pressure, a notable improvement over the OEM cast or stamped-style wastegates, which can let pressure escape and diminish performance. This turbocharger is not just about power; it also delivers superior performance with faster spooling and improved throttle response, translating to quicker acceleration and a more responsive driving experience. It is fully rebuildable and comes as a drop-in replacement with all necessary O-rings, making maintenance straightforward and ensuring long-term reliability.
With the included Turbo-Master adjustable mechanical wastegate controller, you gain full control over drive pressure relief, further enhancing throttle response and boosting overall performance. The turbocharger is backed by a full 1-year warranty, providing you with peace of mind and support. Not only does this turbocharger increase horsepower and reduce EGTs, but it also improves surge control and airflow compared to both stock and modified turbos. For those operating at high elevations, the stock .84 AR exhaust housing will fit, though you might experience slightly higher exhaust temperatures. This turbocharger is the perfect upgrade for enthusiasts seeking a dramatic improvement in power, efficiency, and driving dynamics for their Powerstroke.
- Wicked Turbo: Features a durable journal bearing system that supports higher boost levels and extends lifespan
- GTP38R: Uses ball bearings, which can wear out more quickly under high stress
- Wicked Turbo: Equipped with the Wicked Wheel 2 billet compressor wheel (66mm inducer, 94mm exducer), enhancing airflow and reducing turbo lag for improved throttle response and power.
- GTP38R: Has a stock compressor wheel with lower airflow capacity, limiting power potential.
- Wicked Turbo: Includes the Turbo-Master adjustable fully mechanical wastegate controller for precise boost control.
- GTP38R: Utilizes a stock wastegate that may be prone to leakage and less effective boost control.
- The Wicked Turbo offers superior performance, including increased airflow, reduced EGTs, and better throttle response, all at a lower cost than high-end alternatives. It’s a high-value upgrade for enhancing your Powerstroke’s power and efficiency.
