The Garrett GTX3576R Gen II supercore is a complete ball-bearing turbocharger supplied without a turbine housing, ready to pair with the GT35 / GTX35 housing that suits your manifold and power goals. It combines the 58mm compressor wheel from the GTX3076R with the larger GT35 turbine, which suits bigger engines that need more exhaust flow. Garrett rates it at 400–750 hp for engines from 2.0 to 4.5 litres.
Gen II compressor wheel aerodynamics deliver up to 20% more power than the original GTX3576R, with a fully machined ported shroud for strong surge resistance.
Key features
- Gen II forged, fully machined compressor wheel aerodynamics
- 8 mm dual ceramic ball bearing cartridge, oil and water cooled
- Fully machined compressor inlet, outlet and ported shroud
- High-flow Gen II compressor housing
- Fully machined speed sensor port (plugged from factory), accepts the Garrett speed sensor kit, sold separately
- Outline-interchangeable with GT and GTX Gen I turbos, so it suits existing piping
- Compatible with all existing GT35 / GTX35 turbine housing kits
Please note: turbine housing is not included. Some product photos show the turbo with a housing fitted. Standard rotation. Maximum allowable shaft speed is 145,000 rpm.
