Garrett TR30R Turbocharger features
T25 type ball bearing cartridge.
The bearing races are made from M50 material and the retainer from silicon-bronze for high temperature capability.
An air-cooled center housing with turbo speed pickup boss.
Thin wall stainless steel turbine housing with V-Band inlet and outlet and attached with a V-Band.
The turbine housing is shielded with an activated carbon cloth heat shield.
Mar-M 247 (nickel-based super alloy is a trademark of Martin Marietta Corporation which became part of Lockheed Martin Inc. in 1995) turbine wheel material is good up to 1050C/1922F turbine inlet temperature.
The compressor housing is attached to a standard back plate with a V-Band.
Billet 5-axis machined aluminum compressor wheel.
