If you’re looking to push the limits of your ride, the Garrett G55-2100 91mm Super Core is a serious contender. This isn’t just any turbo; it’s designed for those extreme horsepower applications that get your heart racing, like Radial vs The World and X275 Drag Racing. I’ve had my hands on this beast, and let me tell you, it’s a game changer.

What sets the G55 apart from its older siblings? For starters, it’s got a high-flowing inconel turbine wheel that’s been engineered to optimize airflow. You’re looking at a solid 15% increase in flow compared to the GTX Gen II, which is a pretty significant boost. Plus, the turbine exducer is now a beefy 106mm—that’s an extra 4mm over the GTX55. You can choose from two stainless steel V-band turbine housings with 1.24 A/R and 1.40 A/R, or go for an open T6 turbine housing available in four different A/R sizes: 1.00, 1.12, 1.24, and 1.40.

The center housing is another highlight. It’s a one-piece aluminum design that not only cuts down on weight but also enhances durability. It features an air-cooled setup and boasts a 16mm dual ceramic ball bearing for smooth rotor dynamics. You’ll also find that it retains the oil inlet and outlet specs from previous GTX designs, which is a nice touch for those of us who like to keep things familiar.

On the compressor stage side, you’ve got options galore with inducer sizes ranging from 85mm to 106mm, each tailored to deliver impressive horsepower ratings. Whether you’re after that quick boost response or sheer power, there’s a size that fits your setup.

  • Supports nearly 3000 horsepower with fantastic boost response
  • Multiple compressor options: 85mm, 88mm, 91mm, 94mm, 98mm, 102mm, and 106mm
  • Enhanced 106mm turbine exducer for better performance
  • 15% more turbine flow compared to the GTX—check the graph for the details
  • Lightweight one-piece aluminum center housing
  • Advanced 16mm dual ceramic ball bearing cartridge
  • Compatible with GTX Gen II turbos for easy upgrades

For those who like to keep their setups tidy, there are plenty of oil fittings, flanges, and components available:

  • Oil feed flange: Product Code: ATP-FLA-040
  • Oil feed gasket: Product Code: GRT-GSK-011
  • Oil drain flange: Product Code: ATP-FLA-035
  • Oil drain gasket: Product Code: GRT-GSK-035
  • Compressor Housing Outlet Flange and Clamp Set: Product Code: ATP-FLS-055
  • Speed Sensor Kit: ATP-ACS-032
  • V-Band Inlet Flange (for Turbo Manifold): Product Code: ATP-FLS-225
  • V-Band Inlet Clamp: Product Code: CLC-CLA-045
  • V-Band Outlet Flange (for Downpipe): Product Code: ATP-FLS-420
  • V-Band Outlet Clamp: Product Code: CLC-CLA-022

And if you need alternate oil fittings and flanges, those are available too. It’s all about making sure you get exactly what you need for your build.
