If you're diving into the world of turbocharging, the T31 V-band Turbine Housing is a solid choice that won't let you down. This little powerhouse is designed to fit snugly with a T3 manifold flange, making it a great addition to your setup. What’s cool is that it comes with a compact 2.5-inch V-band outlet, which is perfect for those tight spaces under the hood.
Now, let’s talk specifics. The V-band outlet is machined from a 2.5-inch, 4-bolt outlet pattern, so you know it’s built to last. This housing is compatible with a range of Garrett turbochargers, including the GT28 series, GTX28, GEN2 GTX28, and even the GT35 lineup. Whether you're running a GTX30 or a GT30R-WG, this turbine housing has got your back.
You’ve got options for turbine housing sizes as well, with .63 A/R and .82 A/R available. That means you can tailor your setup to match your performance goals. The T3 inlet flange makes installation straightforward, and you can choose between a standard T31 V-band flange outlet or go for a welded GT 3-inch V-band outlet if that suits your needs better.
When it comes to the outlet parts, you’ve got a few choices:
| Outlet Options | Flange (Down-Pipe Side) Product Code | Clamp or Fasteners Product Code(s) | Gasket Product Code |
