Garrett GTX3076R Gen II Turbo

The Garrett GTX3076R Gen II Turbo Brings Modern Technology and Superb Power to Your Car

The Garrett Gen II GTX3076R dual ball bearing turbo is the evolution of the infamous GT30R, which is one of the most versatile turbos ever created. With this turbo you'll get a lot more power while also keeping good throttle response. Merging the Gen II ultra high flow compressor wheel featuring low-inertia Garrett 8-Blade technology and ceramic ball bearing, the Gen II GTX30 suits single turbo, twin-turbo, and a plug-n-play direct fit upgrade to the multitude of pre-existing GT30R legacy turbo kits.

GTX30 compressor housing is a 0.60 a/r with 4″ inlet / 2″ outlet and built-in ported shroud for a broad surge margin. Now includes a fully machined speed sensor port for a turbo speed sensor kit.
