FAQ
Will this turbo work on both 12-valve and 24-valve 2nd-Gen trucks?Yes. It’s a drop-in upgrade for 1994–2002 5.9L Cummins (both 12V and 24V). Verify your supporting mods and exhaust connections before install.
Do I have to run an HX40 downpipe with the 14cm housing?Yes — the 14cm housing uses an HX40/Marmon outlet and requires a 4" HX40-style downpipe and clamp. See the recommended parts above.
What fueling/supporting mods are recommended?The PhatShaft 64 is designed for daily/tow rigs with mild fueling upgrades (injectors, lift pump, tuning). Keep an eye on drive/boost and EGTs, and consider manifold studs and a boost elbow.
Is it a good match for heavy towing?Yes. The 14cm housing helps control EGTs under load while maintaining good street manners.
