FAQ

Q: Will this turbocharger fit my Cummins 4BT engine in a 1994 Dodge Ram?
A: Yes, this is a direct replacement for the Holset HX25W used on the 4BT in Dodge Ram trucks from 1989 to 2002. Ensure your engine has the standard T3 flange outlet.

Q: What maintenance is required after installing this turbo?
A: Use high-quality diesel engine oil (15W-40 recommended) and change the oil filter simultaneously. Allow the engine to idle for 30 seconds after heavy use before shutdown to cool the turbo bearings.

Q: Do I need to adjust the fuel pump after replacing the turbo?
A: For stock applications, no adjustment is necessary. For modified engines, we recommend consulting a diesel specialist to recalibrate the fuel injection pump to match the new boost levels and prevent over-fueling.
