If you're looking to crank up the performance of your ride, the Garrett G30-660 turbo assembly kit is definitely worth a look. This isn't just any turbo; it's designed for serious enthusiasts who know what they want. With a 3-inch inlet and a 2-inch outlet compressor housing, this kit packs a punch. The 1.06 A/R divided T4 (Twinscroll) entry combined with a V-Band outlet turbine housing means you get quicker spool times and better boost control—perfect for those who want to push their setup to the limit.
One of the standout features here is the new G Series compressor wheel aerodynamics. This isn't just marketing fluff; it really does make a difference in how efficiently the turbo operates. Plus, the fully machined speed sensor and pressure ports mean you're getting reliable readings, which is crucial when you're tuning for performance.
Whether you’re running a standard or reverse rotation setup, Garrett's got you covered. The kit comes with an oil restrictor and water fittings right out of the box, so you can dive into your installation without scrambling for parts. And speaking of durability, the one-piece center housing and backplate are built to last, which is something you’ll appreciate when you’re pushing your engine hard.
For those who like to customize their setup, there are four water jacket ports, giving you flexibility in how you route your coolant. And let’s not forget about the materials—this turbo features a Mar-M turbine wheel that can handle temperatures up to 1050°C (1922°F). The stainless steel turbine housings also match that temperature rating, so you know they’re built for the long haul.
Now, let’s get into some specs that matter. The compressor wheel inducer measures 54mm, while the exducer is 67mm. With a trim of 65 and a compressor housing A/R of 0.70, you’re looking at a solid setup that can deliver when you need it. The turbine wheel inducer is 60mm with an exducer of 55mm and a trim of 84, making it a well-rounded choice for various builds.
Installation? No sweat. The kit includes everything you need, like the outlet V-Band flange and clamp, T4 divided gasket, and oil drain flange. Each part is designed to fit seamlessly, so you won’t find yourself making extra trips to the parts store.
In short, if you’re serious about boosting your vehicle's performance, the Garrett G30-660 turbo assembly kit is a solid investment. It’s built for the long haul, packed with features that real enthusiasts will appreciate, and it’s just waiting to take your ride to the next level.
