If you're looking to boost your ride's performance, let me tell you about the BLACK Garrett GT28RS turbocharger, also known as the GT2860RS. This little beast is a dual ball bearing turbo that really shines when it comes to small displacement engines, especially those up to 2.2L. I’ve had my fair share of turbo experiences, and I can confidently say that this one has the quickest spool-up time I've seen compared to others in its class.
With a flow capacity that can push around 350HP, this turbo is not just about numbers; it’s about the thrill of driving. The .64 A/R turbine housing comes with a T25 5-bolt internal wastegate and a 1 bar actuator, making it a solid choice for anyone looking to enhance their engine's performance without diving into a full-blown rebuild.
Now, let's get into the nitty-gritty specs that make this turbo tick:
When it comes to installation, you’ll want to make sure you have the right fittings and components. For coolant, you’ll need two 14mm fittings and lines. The oil setup is straightforward too; I recommend the -4 AN oil feed with a built-in restrictor (check out Product Code: ATP-OIL-021). Don’t forget the oil drain flange (ATP-FLA-010) and gasket (GRT-GSK-008) to keep everything sealed tight.
For the inlet and outlet, you’ve got options: the stainless steel inlet flange (ATP-FLS-037) is solid, but if you’re on a budget, the mild steel version (ATP-FLS-002) will do the job too. Make sure to grab the corresponding gaskets (GRT-GSK-004 for inlet and ATP-GSK-016 for the 5-bolt outlet) to avoid any headaches down the road.
In short, the GRT-TBO-M15 ATP Turbo Garrett GT28RS is a game-changer for anyone serious about performance. It’s reliable, efficient, and has the kind of responsiveness that makes driving a pure joy. Whether you’re hitting the track or just want to feel that rush on the street, this turbocharger is worth considering.
