Garrett G55-2250 94mm Super Core (Part# 880547-5004S)

If you are hunting for 2000+ horsepower, this is what you’re looking for. The Garrett G55-2250 (Part# 880547-5004S) is a serious piece of hardware designed for drag cars and max-effort racing builds. This Super Core gives you the complete G-Series rotating assembly and compressor housing straight from Garrett, so you know the tolerances are spot on.It uses a 94mm compressor wheel that’s built to move massive amounts of air under high boost. Since it’s a Super Core, you get the center section (CHRA) and the compressor cover pre-assembled. You’ll just need to source your own turbine housing to match your manifold setup.

The Breakdown:

  • The 94mm Wheel: It’s big, it’s efficient, and it’s meant to make power at high boost.
  • Dual Ball Bearing: Garrett’s signature setup. It handles the high heat and heavy thrust loads of racing way better than a standard journal bearing ever could.
  • Ready to Build: Since the compressor side is already set, you aren't risking alignment issues or assembly errors.
  • High-Flow Efficiency: It’s a G-Series unit, so you’re getting the best airflow map Garrett currently makes for this frame size.

Fitment & Build Notes:

  • Usage: Competition drag racing and custom high-HP builds.
  • Important: This is Super Core only. It does not include a turbine (exhaust) housing. You need to make sure you have the right G55-series housing for your manifold before you order.
  • Street Use: You can run it on the street if your build is wild enough, but this thing is really designed for the track.

Common Questions:

Is the turbine housing in the box?
No. You’re buying the Super Core (CHRA + Compressor Housing). The turbine housing is sold separately.
Is this a bolt-on for my car?
No. This is a universal racing part. To run this, you need a custom turbo manifold, custom intake and exhaust piping, and a custom tune. Don't buy this thinking it's going to swap onto a factory turbo setup.
How much power can this actually make?
The "2250" rating is for builds hitting that 2250hp mark. Obviously, that depends on your engine, how much boost you run, and your fuel system. It’s definitely not for a mild daily driver.This style avoids all the "AI traps" like over-explaining or using words like "unleash" or "revolutionize." It’s just technical facts for a customer who knows what they are doing.
