FAQ
Will this turbo bolt to my stock manifold?Yes. It’s a direct-fit S300 variant for 2nd-Gen 5.9L Cummins using the stock T3 manifold. The outlet is HX40-style, so plan on an HX40 4" downpipe for best fit.
Is a 12cm² housing too small for towing?
No. The 12cm² housing is chosen for quick spool and strong low- to mid-range response, ideal for towing with mild fueling upgrades.
Do I need to tune the truck after installing?
Tuning isn’t required to run the turbo, but proper fueling and monitoring (boost/EGT) will optimize performance and keep EGTs in check.
What downpipe should I use?
Use an HX40-style 4" downpipe. See our HX40 downpipes and HX40DP2 kit.
Is this CARB approved?
Not CARB legal. Not for sale or use in California on pollution-controlled vehicles.
