Turbocharger for Ford F-350 (1994-1997) 7.3L

Direct-Fit Replacement Turbocharger for 1994-1997 Ford F-350 (OBS)

What it Does: The replacement turbocharger restores factory boost pressure and volumetric efficiency on the 1994-1997 Ford F-350 by eliminating shaft play, oil blow-by, and drive pressure leakage.

The Stock Ford F-350 Turbocharger Wear Problem

The factory Garrett TP38 turbocharger on the OBS 7.3L Power Stroke is susceptible to severe journal bearing degradation, dynamic seal blow-by, and carbon coking in the oil passages after decades of high-heat towing cycles. Worn thrust bearings produce lateral shaft deflection, allowing the 85.0 mm compressor wheel to contact the housing. This induces catastrophic boost leaks, elevated exhaust gas temperatures (EGTs), heavy oil ingestion into the intake plenum, and pronounced power loss under load.

The Engineering Solution

This direct-replacement unit features a high-speed dynamic balanced rotating assembly designed to maintain hydrodynamic stability and prevent rotational friction under severe thermal loading. Engineered with an OE-specification 1.15 A/R cast-iron turbine housing, a 76.2 mm turbine wheel (83.9 trim), and an 85.0 mm compressor exducer (49.0 trim), it mates seamlessly to the factory pedestal and exhaust collector. Precision oil feed and drain ports maintain steady hydrodynamic lubrication to eliminate boost taper and safeguard against oil starvation under heavy engine loads.

Frequently Asked Questions & Fitment Warnings

Does this fit the OBS F-350?

Yes, this is a direct fit for the 1994-1997 Ford F-350 equipped with the 7.3L Power Stroke direct-injected diesel engine; it does not fit older naturally aspirated 7.3L IDI platforms.

What critical service must be performed before operating the new turbo?

You must flush or replace the oil feed and drain lines, pre-lube the center bearing housing with fresh oil, and complete an engine oil and filter change to prevent premature bearing failure.
