If you’re looking to take your ride to the next level, the Garrett G30-770 reverse turbo assembly kit is worth a serious look. This isn’t just another turbo; it’s a powerhouse designed for those who want to push the limits. With a 4-inch inlet and a 2-inch outlet compressor housing, it’s built to deliver serious performance without compromise. The 1.21 A/R on the turbine side means you’re getting the kind of response that’ll make your engine sing.
One of the standout features here is the new G Series compressor wheel aerodynamics. This isn’t just marketing fluff; it actually improves airflow, which translates to better efficiency and more power. You’ll also appreciate the fully machined speed sensor and pressure ports that make tuning and monitoring a breeze. Plus, whether you’re running a standard or reverse rotation setup, this kit has you covered.
What I really dig is the one-piece center housing and backplate. It’s all about durability, and this design minimizes the chances of failure under pressure. There are also four water jacket ports, giving you flexibility for your installation. And let’s not forget about the Mar-M turbine wheel material—it’s rated for temperatures up to 1050°C (that’s 1922°F for those of us still in the old school). The stainless steel turbine housings can take the heat, so you know this turbo is built to last.
Now, let’s get into some specs. The compressor wheel inducer measures 58mm, and the exducer is 71mm, with a trim of 65. On the turbine side, you’ve got a 60mm inducer and a 55mm exducer with a trim of 84. The compressor housing A/R is 0.72, which helps with spool time and overall responsiveness. The turbine housing has a 3-inch O.D. V-band inlet and a 3.55-inch outlet, ensuring a solid connection to your exhaust system.
When you purchase this kit, you get everything you need to get started: an oil feed restrictor fitting, two coolant fittings, and all the necessary V-band clamps for the turbine housing inlet and outlet. Installation hardware is included, too, so you won’t be scrambling for parts mid-project. This includes the inlet and outlet V-band flanges, oil drain flange, gasket, and even the boost pressure port fitting.
In short, the Garrett G30-770 is built for enthusiasts who want to maximize their vehicle’s potential. It’s not just about adding power; it’s about doing it reliably and efficiently. If you’re ready to take the plunge, this turbo assembly kit is a solid choice that won’t disappoint.
