If you're on the hunt for a turbo that packs a serious punch without taking up too much space, the Garrett G-Series G25-550 is a game changer. This little beast can push out up to 550 horsepower, which is pretty impressive for such a compact unit. I've had my hands on this turbo, and let me tell you, it really does deliver on performance.

One of the standout features is the ultra high flow G-Series compressor wheel. It’s designed to maximize airflow, making sure your engine breathes easy, even when you're pushing it hard. And the turbine wheel? It's made from high heat resistance Mar-M Alloy, which is no joke. With a rating of up to 1050 degrees Celsius, you can trust it to handle the heat, whether you're hitting the track or just cruising around.

Now, let’s get into some of the nitty-gritty specs that matter. The compressor wheel has an inducer size of 48mm and an exducer size of 60mm, with a trim of 65. That means it’s built to deliver serious boost while maintaining efficiency. The compressor housing inlet is a solid 3 inches, and the outlet is 2 inches, with an A/R of .70, making it a well-rounded choice for various setups.

On the turbine side, you’ve got an inducer at 54mm and an exducer at 49mm, with a trim of 84, which helps in achieving that quick spool time we all crave. This turbo is all about getting you that responsive power without the lag.

For those of you looking to set this up, you’ll need a few extra components. The oil drain flange (Product Code: ATP-FLA-010) and gasket (GRT-GSK-008) are essential, along with the fasteners (MIA-FST-034) to keep everything tight. Don’t forget about the boost pressure port fitting (ATP-FTG-198) and the speed sensor kit (ATP-ACS-032) to round out your installation.

In short, the G25-550 is a turbo that combines size, power, and durability in a way that’s hard to beat. Whether you’re building a street machine or a track monster, this turbo is worth considering. It’s not just about the numbers; it’s about the experience it brings to your ride.
