So, you're looking at the Garrett GT28RS, also known as the GT2860RS, and let me tell you, it's a gem for anyone pushing small displacement engines—think up to 2.2 liters. This turbo is all about that quick spool time, which is a game changer on the track or the street. If you've been around the block with turbos, you know that responsiveness is key, and this one delivers.
With a flow capacity of around 350 horsepower, it’s got the muscle to back up its reputation. The compressor wheel measures in at 60 mm with a trim of 62, while the turbine wheel sits at 53.85 mm with a 76 trim. These specs may sound technical, but they translate into real-world performance that you can feel. The dual ball bearing design is what really sets it apart from the crowd—less lag means more fun, right?
When it comes to installation, you’ll need a couple of things to get it all hooked up properly. For coolant, you’ll want to grab two 14mm fittings and lines. Oil feed? Go for the -4 AN option with a built-in restrictor (check out product code ATP-OIL-021 for that). And don’t forget the oil drain flange (ATP-FLA-010) and gasket (GRT-GSK-008) to keep everything sealed tight.
If you’re planning to weld, the T3 inlet flange in stainless (ATP-FLS-038) is a solid choice, and there’s a mild steel option too (ATP-FLS-001) if that’s more your style. You’ll also need the gasket for the T3 turbine inlet (GRT-GSK-005) and a 4 bolt outlet flange for your downpipe (ATP-FLS-084) along with its gasket (ATP-GSK-012).
In short, the Garrett GT28RS is a turbo that not only performs but also brings a lot of versatility to the table. Whether you're building a street beast or a track-ready machine, this turbo is worth considering. It’s not just about the numbers; it’s about the experience, and this turbo makes every drive a little more thrilling.
