If you're looking to up your turbo game, the Garrett GT2871R ball bearing turbocharger is a solid choice. It's got this .63 A/R T31 "narrow" 4-bolt turbine housing that really packs a punch—potentially over 450 horsepower, which is nothing to scoff at. I've had my hands on this beauty, and let me tell you, it delivers.
What sets this turbo apart? First off, it features a genuine Garrett GT Aero compressor wheel that not only looks slick but also performs like a champ. The Inconel turbine wheel is another highlight; it's built to withstand some serious heat, so you know it's tough. Plus, the dual ball bearing CHRA rotating assembly means smoother operation and quicker spool times, which is a game-changer when you’re trying to get that boost on demand.
Now, let’s dive into some specs that matter. The compressor wheel has an inducer size of 53.1mm and an exducer of 71mm, with a trim of 56. The housing A/R is 0.60, which helps with efficiency. On the turbine side, you’re looking at a 53.9mm inducer and a 47mm exducer with a trim of 76. It’s a solid setup that balances power and responsiveness.
When it comes to installation, you’ll want to think about the coolant and oil fittings. You’ll need two 14mm coolant fittings and lines to get the water flowing right. For oil, a -4 AN feed line with a built-in restrictor (check out product code ATP-OIL-021) is the way to go. Don’t forget the oil drain flange (ATP-FLA-010) and the gasket (GRT-GSK-008) to seal everything up tight.
If you’re welding in a T3 inlet, there are stainless and mild steel options (ATP-FLS-038 and ATP-FLS-001, respectively). Also, grab a T3 turbine inlet gasket (GRT-GSK-005) and a 4-bolt outlet flange for your downpipe (ATP-FLS-084), along with its corresponding gasket (ATP-GSK-012) to ensure a leak-free setup.
Overall, the Garrett GT2871R is a well-rounded turbo that’s built for those who want a reliable performance upgrade. Whether you’re racing or just enjoying a spirited drive, this turbo can take your ride to the next level.
