The Garrett GTX3076R Gen II supercore is a complete ball-bearing turbocharger supplied without a turbine housing, ready to pair with the GT30 / GTX30 housing that suits your manifold and power goals. Its 58mm compressor wheel on the GT30 turbine makes it one of the most popular choices for 2.0–3.0 litre street and track builds, rated by Garrett at 400–750 hp for engines from 1.8 to 3.0 litres.
Gen II compressor wheel aerodynamics deliver up to 20% more power than the original GTX3076R, with a fully machined ported shroud for strong surge resistance.
