The SPOOLOGIC Advanced Turbo Rebuild Kit SL-900-001-K02 is a bundled, complete rebuild package for 1994-1997 Ford F-250 F-350 Super Duty 7.3L Powerstroke; 1995-1997 Ford E-350 Econoline 7.3L Powerstroke Garrett TP38 applications. It combines a SPOOLOGIC base rebuild kit with a new cast compressor wheel, turbine shaft, so you have everything needed to restore the turbo to factory performance in one box.

Every part in this kit is built to OEM specifications and pre-tested for fitment and balance. This is a complete, ready-to-install package — no sourcing individual components, no mismatched tolerances, no waiting on backorders. Built for the Garrett TP38 on 7.3L Powerstroke applications.

Common Garrett TP38 Failure Symptoms

If your 7.3L Powerstroke turbo is showing any of these symptoms, a full rebuild is recommended:

• Wastegate actuator drift or stuck operation — overboost or underboost, inconsistent boost between runs
• Excessive shaft play or oil seal leakage — blue smoke at idle, oil residue in the intercooler piping, end-play beyond OEM tolerance
• Bearing failure — whining, grinding, or whistling that scales with RPM
• Loss of boost and reduced power — turbo not holding rated boost, sluggish acceleration, excess EGT

Advanced Rebuild Kit — Everything in One Box

Each SPOOLOGIC advanced kit bundles the SL-210 base rebuild kit with the additional wear and upgrade components that fail or get replaced at rebuild time. Buying the kit costs less than sourcing the parts separately and guarantees every part matches the Garrett TP38 platform.
