So, you’re looking at the Garrett GTW3684R T3 turbo with a .63 A/R turbine housing—this little beast is a solid choice for anyone wanting to kick their boost game up a notch. It’s got a T31 4-bolt exit, which makes it super easy to pair with your downpipe. Seriously, if you're into building your ride for some serious power, this turbo is worth checking out.
Now, let’s dive into the details. The .63 A/R is just right for those who want a good balance between response and top-end power. It spools up quick, so you’re not left waiting around for boost to hit. If you’ve got a project car that needs a turbo upgrade, this one can really help you clear 35-inch tires on a 2024 Tundra with just a bit of trimming, which is pretty handy if you're looking to beef up your stance without going overboard.
When it comes to installation, you’ll need a couple of things to make it all fit right. Grab the ATP-FLS-084 for the T31 narrow 4 bolt 2.5” flange on the downpipe side, and don’t forget the ATP-GSK-012 gasket to keep everything sealed up nice and tight. Trust me, you don’t want any boost leaks messing with your setup.
This turbo isn’t just about numbers on paper; it’s about real-world performance. Whether you’re hitting the track or just cruising around, the Garrett GTW3684R is designed to deliver.
