Product Description
Center-mount S300 power for your 5.9L. The INDUSTRIAL INJECTION 227436 S300 SX-E 62/74 single turbo kit places a proven BorgWarner SX-E in a 2nd-gen–style, center-mount location on a high-flow T4 manifold for quicker spool, cooler EGT, and clean top-end power. The 62/74 with a 1.0 A/R is a street-friendly sweet spot for tuned daily drivers and tow rigs that want ~600 HP potential with headroom for future fueling.
Fitment
- 2003–2007 Dodge Ram 2500/3500 5.9L Cummins (24V common-rail)
- Direct 2nd-gen–style (center mount) conversion using a T4 3-piece manifold
What’s Included
- BorgWarner S300 SX-E 62mm/74mm turbocharger, 1.0 A/R turbine housing
- High-flow T4 3-piece exhaust manifold (2nd-gen style)
- Cold air intake assembly
- Passenger-side intercooler pipe & compressor outlet elbow
- HX40-style downpipe
- Oil feed/return lines, clamps, and turbo mounting gaskets
Why SX-E 62/74 1.0 A/R?
- SX-E upgrade hardware: forged-milled (FMW) compressor wheel & 360° thrust bearing for durability
- Balanced street/tow manners with strong mid-range and top-end on built 5.9L CR setups
- 2nd-gen center mount improves drive pressure balance and serviceability
Recommended Parts (CPP internal links)

Helpful Notes
- Supports ~550–600 HP with adequate fuel, air, and tuning. Verify drive pressure, shaft speed, and EGT on aggressive setups.
- A 2nd-gen kit relocates the turbo; check clearance for intake/charge pipes, downpipe, and heat management.
- Head studs and quality gaskets are strongly recommended above stock power levels.
FAQ
What exactly is “2nd-gen style” on a 2003–2007 truck?It centers the turbo/manifold between cylinders 3–4 (like 1994–2002 trucks) using a T4 3-piece manifold. This improves access and can help with drive pressure balance versus the factory 3rd-gen location.
Is the 62/74 1.0 A/R good for towing?Yes. With proper tuning and fueling, the 62/74 with a 1.0 A/R offers quick enough response for heavy daily use while keeping EGT in check, making it a strong street/tow choice.
What’s included versus what do I still need?The kit includes the SX-E turbo, T4 manifold, intake, intercooler tube, HX40 downpipe, oil lines, clamps, and gaskets. We recommend adding head studs, fresh manifold/turbo gaskets, quality boots/clamps, and a turbo blanket for heat control.
Do I need custom tuning?Custom tuning is recommended to optimize spool, fuel delivery, and EGT control, especially with larger injectors or CP3 upgrades.
