If you’re hunting for a turbo that really delivers, check out the ATP Turbo Garrett G-Series G40-900. This bad boy features a 62mm compressor wheel and a 1.06 A/R V-band inlet and outlet turbine housing, making it a solid choice for anyone looking to crank up the power on their ride. Seriously, whether you’re rocking a 2.0L or pushing up to a 6.0L engine, this turbo is built to perform.
One of the standout features here is the quick spool. You get that boost when you need it without the lag that can ruin your day. The G-Series compressor aero is a game changer, boosting flow by up to 32% compared to the GTX4088R. That means more air, more power, and a whole lot more fun behind the wheel.
Let’s talk about the build quality. This turbo comes with dual ceramic ball bearings housed in steel cages, which not only help with reliability but also keep things running smoothly at high speeds. The turbine side is no slouch either—thanks to the Inconel turbine wheel with a 77mm inducer, it can handle flows up to 43 lbs/min. You’re going to feel the difference.
Another perk? The lightweight aluminum backplate and fully machined speed sensor and pressure ports make installation a breeze. Plus, the compact compressor housing design means it won’t hog space in your engine bay. You can fit it in without a ton of hassle, which is always a win.
Here’s a quick rundown of the specs:
And if you’re wondering about fittings and flanges, we’ve got you covered. You’ll need a couple of 14mm coolant fittings and lines, along with the right oil feed flange and gaskets. Here’s a quick list:
