Want to keep your existing exhaust and Intercooler plumbing? This this the upgrade for you !

60mm Turbo Upgrade Compressor Housing & Wheel combo (60mm inducer) for 1989-1994 Dodge Cummins Turbochargers.

Genuine Holset, 60mm inducer, Upgrade Compressor Housing & Wheel combo for 1989-1994 Dodge / Cummins 5.9L diesel Turbochargers. Intercooled trucks! 

This Housing & Wheel combo is the largest available, genuine Holset housing & wheel set to fit the stock turbo! It gives a massive increase to the compressor flow capacity and adds a map width enhancement slot to reduce compressor surge on 89-1994 air-to-air intercooled trucks. It increases the compressor wheel inducer size from 54mm on 1989-1993 1st gen. trucks, and 56mm on 1994, 2nd gen. trucks to a 60mm inducer.

This housing & wheel combo is a direct fit on these year trucks, if they have the O.E. part number turbocharger. (Attaches to the center housing with a v-band, not snap ring connection)

The Housing clamp holds the compressor housing and the turbine housing together. You need to replace this if the existing clamp is broken or damaged. You can reuse the clamp

The outlet v-band clamp and o-ring needs to be replaced only if the clamp or o-ring are damaged. You can reuse the clamp and the o-ring. 

This would be a fine time to rebuild your turbo when adding this compressor upgrade. See the option in the menu on the right.
