PDR Diesel Inc. The turbo diesel performance specialists!

PDR S300 Turbo The PDR Super S300 is part of the Schwitzer S300 family. It is recommended as a replacement for the existing turbos on 1994 - 2002 Dodge RAM diesels. The Super S300 turbo is intended for moderately upgraded trucks that tow and/or for those running up to 400hp. Above 400hp you should consider the PDR Twin Turbo systems.

Think HX40 air flow with HX35 spool up.

This is achieved by using Borg Warner's unique extended tip compressor wheel technology and low inertia, full-floating journal bearings. The result is a compressor that flows a decent amount of air, and yet has excellent spoolup. On the exhaust side, the Super S300 turbo comes with a dual volute wastegated exhaust housing. Like an HX40, the exhaust housing is a 4" outlet and requires the use of an HX40 downpipe and clamp.

Fits 1994-2002 Dodge RAM diesels. We also have them available for 03-06 RAM's.
