If you’re looking to push your small displacement engine to new heights, the ATP Turbo 400hp Garrett GT2871R Turbo is a solid choice. This little powerhouse features a dual ball bearing setup with a T25 style turbine inlet, which means you’ll get that quick spool-up time that can really make a difference on the track or the street. When you grab this turbo with the T25 housing, it comes with the internal wastegate already pre-assembled, so you can hit the ground running.
Now, if you’re working with an older T3 setup, don’t sweat it. There’s an optional “T3/T4 drop-in” turbine housing that makes retrofitting a breeze. Just keep in mind that if you go that route, you won’t get the internal wastegate assembly included, but it’s a small price to pay for the ease of installation.
This turbo is designed for engines up to 2.2L, and it really shines when it comes to spool-up time. You’re looking at a flow capacity of around 400HP, which is fantastic for those who want to step up their game without a massive overhaul. The external dimensions are nearly identical to the GT28RS, so if you’re already running that, swapping to this turbo is straightforward—no need for a major rework of your setup.
Let’s break down some of the specs that make this turbo tick:
When you’re ready to order, just select your preferred turbine and compressor housing options. And don’t forget to drop a note in the “Add Comments About Your Order” section during checkout to specify your turbine housing choice. There are four options to pick from, so you can tailor this turbo to fit your build just right.

And if you’re interested, there’s also the K24_K26 option available in .63 or .82 AR. Just keep in mind there’s no image for that turbine style. Overall, the GRT-TBO-022 ATP Turbo 400hp Garrett GT2871R Turbo is a solid upgrade that can help you unleash the full potential of your engine.
