Pavel's Racing Engines is pleased to offer this high-quality billet compressor wheel fit for the Garrett GTP38R turbo found as an upgrade in the 1999-2003 Powerstroke 7.3 engine commonly fitted to the Ford F250 and F350 trucks. This compressor wheel compatible with Garrett GTP38R part number: 729567-0001 and 73619-5004s. This compressor wheel can also be fitted to the TP38 and GTP38 turbochargers from earlier model Powerstroke 7.3 with compressor housing machining. Compressor wheel dimensions are listed below. Please confirm the dimensions of your original compressor wheel before ordering. 

This compressor wheel is not a direct swap for the 7.3 Powerstroke GTP38 turbo. This compressor wheel is much larger and requires compressor housing machining. W offer housing machining service as well as complete turbo rebuilds. Basic turbo rebuild price starts at $550 and includes balancing and a rebuild kit with a 360-degree thrust bearing. Compressor housing machining service to fit this compressor wheel costs $175. 

This eBay listing includes one compressor wheel. Professional installation highly recommended. 

Inducer: 66.0mm

Exducer: 88.0mm

Extended tip: 93.8mm

Blade geometry: 10 blade

Rotation: reverse  

Standard features and advantage:

• 10 blade design: Conventional cast aluminum Garrett compressor wheel uses a 6 tall and 6 short or 5 tall and 5 short blade geometry. Garrett has shown substantial air flow gains, as evident by compressor map comparisons, of this 10 blade compressor wheel design over the previous versions.
• Extended tip design: Conventional compressor wheel tips end perpendicular to the exducer diameter. Extended tip technology originally developed as "cheater" compressor wheels for racing use. Standard exducer diameter is 88mm, while extended tip compressor wheels had 93.8mm exducer diameter. This of it like a larger area of an airplane wing allowing for increased lift. The larger surface area allows for increased flow volume at same turbo speed.
• Slim blade design: Performance feature designed to increase air flow. Slim blades have a smaller cross-section allowing more area between blades for air. Flow is increased at same turbo speed. Thinner blades also weigh less for reduced moment of inertia and faster spool.
• Slim hub design: Another feature designed to increase air flow. Slim hub increased air volume with each rotation. Flow is increased at same turbo speed. Smaller cross-section hub weighs less for a reduced moment of inertia and faster spool.
• Material selection: Conventional compressor wheels made by casting aluminum alloy. PRE compressor wheels machined from billet aluminum alloy block. Billet blocks are forged. This compacting of molecules increases material density and strength. Increased strength of billet material allows for reduced blade and hub cross-section and weight reduction without increasing internal stresses. 
• Balancing: PRE compressor wheels are inspected and computer balanced to less than 0.5g-cm^2. This does not mean compressor wheel should be swapped as-is. Stack-up disbalance is always a factor and compressor wheel balancing should always be performed by a professional using entire rotating assembly.
• Weight: PRE billet compressor wheels, on average, weigh 8% less than the cast aluminum version. This translates to improved spool and response from reduced moment of inertia.
