Garrett G55-2450 98mm Super Core Turbocharger

If you’re looking to push the limits of your ride, the Garrett G55 turbo is where it's at. This isn’t just another turbo; it’s built for serious horsepower, especially if you’re into Radial vs The World or X275 drag racing. The standout features here are a high-flowing inconel turbine wheel and a one-piece aluminum center housing that really set this turbo apart from the older models.

Turbine Stage

The new turbine wheel is engineered with optimized G Series aerodynamics, giving you a flow increase of up to 15% compared to the GTX Gen II. That’s not just numbers; it translates to more power on the track. Plus, the larger 106mm turbine exducer (that's 4mm bigger than the GTX55) means you’re getting improved efficiency. You can choose from two stainless steel V-band turbine housings with A/R ratios of 1.24 and 1.40, or go with an open T6 turbine housing available in four different A/R sizes: 1.00, 1.12, 1.24, and 1.40. Plenty of options to fit your setup just right.

Center Housing

Weight matters when you’re racing, and the one-piece aluminum center housing helps keep things light. It’s air-cooled and features a 16mm dual ceramic ball bearing that enhances rotor dynamics, ensuring everything runs smoothly. Plus, it keeps the oil inlet and outlet specs from previous GTX designs, so there’s no hassle with fitment.

Compressor Stage

The G55 offers a range of compressor stages with inducer sizes from 85mm all the way up to 106mm. Each size has its own horsepower rating, so you can pick what fits your power goals best.

Key Features

  • Supports nearly 3000 horsepower with quick boost response.
  • Multiple compressor options: 85mm, 88mm, 91mm, 94mm, 98mm, 102mm, and 106mm.
  • 106mm turbine exducer (+4mm over GTX55).
  • 15% more turbine flow compared to GTX – check the graph below for details.
  • Lightweight one-piece aluminum center housing.
  • 16mm dual ceramic ball bearing cartridge for smooth operation.
  • Interchangeable outline with GTX Gen II turbos – easy upgrade!
