If you're diving into the world of turbocharging, the Garrett GT3071R is a solid choice that won't let you down. This turbo features a 4-inch inlet and a 2-inch outlet, along with a .82 A/R T3 turbine housing that’s built to handle some serious power—think 480+ HP potential. It’s got the kind of flow that can really wake up your engine.
What’s cool about this turbo is that it comes equipped with a genuine Garrett GT Aero compressor wheel and an Inconel turbine wheel. The materials are top-notch, designed to withstand high temperatures and pressures, which is crucial if you’re pushing your setup hard. Plus, the dual ball bearing CHRA rotating assembly means you’ll get quicker spool times and better reliability. No one likes a turbo that’s sluggish or fails on them, right?
Now, let’s talk specs because I know that’s what you’re really after. The compressor wheel has a 53mm inducer and a 71mm exducer, with a trim of 56. The compressor housing A/R is set at 0.50, which helps balance efficiency and power delivery. On the turbine side, you’re looking at a 60mm inducer and a 55mm exducer, with a trim of 84. It’s a solid setup for anyone looking to get serious about performance.
When it comes to installation, you’ll need a few extra components to get everything running smoothly. For coolant, you’ll want to grab two 14mm coolant fittings and lines. The oil feed options are straightforward; go for a -4 AN 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)—those are essential to keep everything leak-free.
For the exhaust side, you’ll need a T3 inlet weld flange; you have the choice between stainless steel (ATP-FLS-038) or mild steel (ATP-FLS-001). And make sure to grab the gaskets for the T3 turbine inlet and the downpipe to ensure a tight seal. The discharge flange is a GT 4 Bolt 3" in stainless steel (ATP-FLS-085), which is pretty durable and will hold up under pressure.
In short, the Garrett GT3071R is a powerhouse of a turbo that can transform your ride. Whether you’re hitting the track or just want to add some serious kick to your daily driver, this turbo is worth considering. Just make sure you have the right fittings and components to get it set up right, and you’ll be ready to enjoy the thrill of boosted performance.
