If you're looking to push the limits of your ride, the Garrett G55 turbo is where it's at. This isn't just any turbo; it's built for those who crave serious horsepower, especially in the Radial vs The World and X275 Drag Racing scene. What sets the G55 apart? Let’s dive into the details.
The G55 features a newly designed turbine wheel that’s all about improved flow. We're talking about a 15% increase compared to the GTX Gen II—yeah, that’s a noticeable upgrade. The larger 106mm turbine exducer gives you an extra 4mm over the GTX55, which means more power potential. You can choose from two stainless steel V-band turbine housings with 1.24 A/R and 1.40 A/R options, plus an open T6 housing available in four different A/R sizes: 1.00, 1.12, 1.24, and 1.40. This flexibility means you can tailor your setup to fit your specific needs.
One of the coolest features here is the one-piece aluminum center housing. It’s lightweight and helps with overall efficiency. Plus, it’s air-cooled and comes with a 16mm dual ceramic ball bearing system that ensures smooth rotor dynamics. It keeps the oil inlet and outlet specs from the previous GTX designs, so you won’t have to worry about compatibility issues.
The G55 compressor stage gives you plenty of options—85mm, 88mm, 91mm, 94mm, 98mm, 102mm, and 106mm inducer sizes. Each size has its own horsepower rating, so you can pick what suits your build best.
To get everything running smoothly, you’ll need some additional parts. Here’s a quick list:
And if you need alternate oil fittings and flanges, don’t worry—those are available too.
