JA-S300 Performance Cummins Turbo

JA-S300 Performance Cummins Turbo - The JA-S300 turbo series features a strong, large shaft, extended tip compressor turbos for aftercooled Dodge Cummins engines. With a 4" exhaust system, free-flowing air box and fuel enough to burn, 350-625 HP is the comfort range for these turbos. The Borg-Warner Turbo Series features extremely durable and responsive chargers. After the initial quick spool-up, the S300 turbos build boost even quicker than other hybrid turbos so that there is plenty of boost at low-end, for towing and, well, for sheer fun. The result is minimal smoke as well as even lower EGT's.

These turbos feature ported shroud compressor housings, well as dual ported wastegates with adjustable actuators set by our shop at about 40 lbs psi. Keep in mind that boost equates to turbine speed and once you exceed "safe" boost levels of a turbo, any turbo will become a candidate for failure. Engine head gaskets and other components are at risk as boost levels approach 50 lbs.

Most customers at or around 500 horsepower report max EGT's under 1400 degrees with this turbo (excluding customers at high altitudes).

A larger, freer flowing airbox (as well as 4" exhaust) is a prerequisite for these high flow turbos. Be sure you get enough air to these turbos by replacing the restrictive air box on the 3rd gen trucks. *Some "high flow filters" only flow 450 CFM. Please allow for 1000 CFM. We personally recommend The AFE series box. If you don't replace the entire intake box then you will more than likely experience compressor surge.

This turbo has the equivalent of a 12cm turbine housing and 62mm compressor wheel.
