If you're looking to give your small displacement engine a serious boost, the Garrett GT28RS, also known as the GT2860RS, is a turbocharger that deserves your attention. This little powerhouse features a dual ball bearing design, which means it spools up quicker than you can say "boost." With a .86 A/R T25 turbine housing and a 1 bar actuator, it’s built for performance and reliability.

What I love about the GT28RS is its versatility. It’s perfect for engines up to 2.2L, making it a fantastic choice for those who want to squeeze out every last bit of horsepower without going overboard. You can expect a flow capacity of around 350HP, which is pretty impressive for a turbo of this size. The spool time is just phenomenal—this thing gets you into the power band faster than most other turbos in its class.

Now, let’s talk specs for a second, because I know that’s what you’re really after:

  • Compressor Wheel Exducer: 60 mm
  • Compressor Wheel Inducer: 47 mm
  • Compressor Wheel Trim: 62
  • Turbine Wheel Inducer: 54 mm
  • Turbine Wheel Exducer: 47 mm
  • Turbine Wheel Trim: 76 trim

When it comes to installation, you’ll need a few additional components to make everything fit perfectly. For coolant, you’ll want to grab two 14mm fittings and lines. The oil feed options include a -4 AN setup with a built-in restrictor (check out product code ATP-OIL-021 for that). Don’t forget about the oil drain flange (ATP-FLA-010) and gasket (GRT-GSK-008) to keep everything sealed up tight.

For the inlet and outlet, you have options too. The T25 inlet flange comes in stainless steel (ATP-FLS-037) or mild steel (ATP-FLS-002), and you’ll need the inlet gasket (GRT-GSK-004) to go along with that. The outlet flange is also available in both stainless (ATP-FLS-088) and mild steel (ATP-FLS-081), and you’ll want to grab the 5-bolt outlet gasket (ATP-GSK-016) to complete the setup.

In short, the Garrett GT28RS turbocharger is a solid investment for anyone serious about boosting their ride. It’s got the specs, the performance, and the reliability that enthusiasts crave. If you’re ready to take your engine to the next level, this turbo might just be the ticket.
