When it comes to building a high performance diesel, finding the sweet spot between fast spool-up, low exhaust gas temperatures (EGTs), and top-end power can feel like a compromise. You often have to choose between lag on the track or a choked-up street truck.

That’s exactly why our Performance 5B468/83 T-4 Turbocharger took off as one of our Top 5 Best-Selling Products for September 2026. Designed and built in-house right here at Stainless Diesel, this unit delivers pure performance for street drivers, heavy haulers, and weekend competitors alike.

Precision Engineering: Built for 650 to 750 HP

Priced at $1,935.00, the 5B468/83 T-4 is engineered to deliver maximum horsepower per dollar without compromising long-term reliability. Built specifically around a strong T-4 turbine footprint and an 83mm turbine wheel, this turbo flows enough air to comfortably back up 650 to 750 horsepower builds.

Key Performance Highlights:

• Proprietary 5Blade Billet Wheel Technology: Our signature 5-blade billet compressor wheel design grabs air instantly, offering hyper-aggressive spooling capabilities, higher air density, and that unmistakable Stainless Diesel whistle.

• Balanced 83mm Turbine Wheel: Paired with a 1.00 A/R T-4 housing, it relieves exhaust backpressure under heavy load, keeping your EGTs safely in check when you put your foot down.

• Heavy-Duty Bearing Structure: Built to sustain high boost pressures day in and day out, making it as reliable on long highway hauls as it is launching on the track.

• In-House Quality Assurance: Designed, machined, and inspected by diesel enthusiasts who know what these machines demand.
