If you're diving into the world of high-performance turbochargers, the Garrett G55-2650 102mm Super Core is a piece of kit you need to check out. This isn't just another turbo; it's built for the big leagues, specifically designed for those extreme horsepower applications like Radial vs The World and X275 Drag Racing. You can feel the difference right out of the box with its new high-flowing inconel turbine wheel and a sturdy one-piece aluminum center housing. These upgrades really set the G55 apart from its older siblings.

Let’s talk numbers. The turbine stage features this newly engineered turbine wheel that boasts optimized G Series aerodynamics, pushing flow up by about 15% compared to the GTX Gen II. The turbine exducer is now larger at 106mm, which is a nice bump of 4mm over the GTX55. You’ve got options too—this turbo comes with two stainless steel V-band turbine housings in 1.24 A/R and 1.40 A/R, plus an open T6 turbine housing that’s available in four different A/R sizes: 1.00, 1.12, 1.24, and 1.40. So, whether you’re building a street monster or a track beast, there’s a setup that’ll fit your needs.

Moving on to the center housing, the one-piece aluminum design not only cuts down on weight but also enhances durability. It’s air-cooled and features a 16mm dual ceramic ball bearing for smooth rotor dynamics. Plus, it keeps the oil inlet and outlet specs from the previous GTX designs, making it easier to swap out if you’re upgrading.

Now, let’s not forget the compressor stage. The G55 offers a range of inducer sizes—85mm, 88mm, 91mm, 94mm, 98mm, 102mm, and 106mm—each tailored for specific horsepower ratings right in the model name. This turbo can support nearly 3000 horsepower while delivering fantastic boost response. That's some serious power on tap.
