Smeding Diesel S475 T4 Turbocharger
The S475 is a big-air single for high-horsepower builds — the 75mm compressor moves the volume heavy fuel demands up top. Expect a bit more lag than the smaller wheels in exchange for real power on the far end, so pair it with fueling and a converter or clutch that match. This is a purpose-built power wheel, not a tow turbo.
Configure it to your build: choose your compressor wheel, exhaust housing A/R, thrust bearing (standard or Extreme Duty steel 360°), and exhaust flange. T4 mounting.
Hand-built and high-speed balanced in the USA before it ships. 1-year unlimited-mileage warranty.
Not sure on housing A/R or bearing choice? Call 636-429-7020 or email [email protected] — we'll match the turbo to your fuel and target power.
