If you're in the market for a serious turbo upgrade, the Garrett GEN2 GTX5544R is a beast you need to consider. This isn't just another turbo; it's the highest flowing model in the Garrett Gen II lineup, specifically designed for those racing classes that cap the compressor wheel inducer at 102mm. Trust me, this turbo is built for performance.
What really sets the GTX5544R apart is its dual ball bearing design, which means quicker spool times and more reliable performance under pressure. I’ve had my hands on this turbo, and the TiAL 1.30 A/R stainless steel turbine housing not only looks great but can handle the heat like a champ. It’s tough enough to take whatever you throw at it.
Let’s talk numbers. This turbo supports over 2,750 horsepower—yeah, you read that right. The .96 A/R compressor housing features a larger volute, which is a game-changer for airflow. The 144mm compressor exducer has been bumped up by 11mm compared to earlier models, which translates to more power and efficiency. Pair that with the GT and GTX turbine housing compatibility, and you’ve got a turbo that’s versatile enough for various setups.
Now, if you're wondering about the nitty-gritty specs, here’s the lowdown:
When it comes to installation, you’ll want to grab some specific parts to get everything running smoothly. Here’s a quick list of what you might need:
