Genuine Holset, 60mm inducer, Upgrade Compressor Housing & Wheel combo for 1991.5-1994 Dodge / Cummins 5.9L diesel Turbochargers.
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 91.5-1994 air-to-air intercooled trucks. It increases the compressor wheel inducer size from 54mm on 1991.5-1993 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)
Great quality product

Literally a 30-60 minute upgrade depending on how much beer you've had to drink. A little more turbo whine than stock and an excellent upgrade in power for the price.

I Bought the GDS 60mm compressor upgrade and the 14cm Exhaust housing. I must say it was well worth the money, the turbo sings an incredibly beautiful song now, and turbo spool is instant. EGTS are significantly hotter but manageable. The staff at GDS are extremely knowledgeable and by far the best people i have worked with when ordering aftermarket parts, especially Steve! I would recommend this turbo to anyone on a budget. Steve again I thank you for your help and patience, and hope to do business with you guys in the future,
