If you’re looking to amp up your turbo game, the GTW3476JB (also known as GTW5857JB) is where it’s at. This journal bearing turbo from Garrett is a solid choice for anyone wanting to push their setup to the next level. With a potential flow of up to 700HP, it’s built for those who are serious about performance without breaking the bank.

Let’s dive into the specs. The compressor wheel has an inducer size of 58.3mm and an exducer size of 76.4mm, which means it’s designed to move some serious air. The turbine wheel is no slouch either, with an inducer at 65.0mm and an exducer at 56.6mm. This setup gives you a solid balance of spool time and power, making it a great pick for street or track builds.

  • Compressor Wheel Inducer: 58.3mm
  • Compressor Wheel Exducer: 76.4mm
  • Turbine Wheel Inducer: 65.0mm
  • Turbine Wheel Exducer: 56.6mm

Now, a heads-up: this isn’t a direct drop-in for the smaller Garrett GT or GTX turbos. The GTW series has a beefier bearing housing, so you’ll need to plan for some extra space in your setup. Plus, the oil feed and return fittings are different, so make sure you grab the right parts to avoid any headaches.

Speaking of parts, here’s what you’ll need for the oil system:

  • Oil feed flange: ATP-FLA-041
  • Oil feed gasket: ATP-GSK-026
  • Oil drain flange: ATP-FLA-042
  • Oil drain gasket: ATP-GSK-027
  • 8mm x 1.25 bolts: MIA-FST-034

When it comes to compressor housing, you’ve got options. The default T04S frame features a 4” inlet and 2.5” outlet with a built-in anti-surge design. If you prefer a little more versatility, the T04E frame with a 2” outlet is also available.

On the turbine side, you can choose from a variety of configurations. Whether you want a T3 inlet with a 2.5” outlet, or a T25 inlet with a built-in external wastegate port, there’s something to fit your needs. Just make sure to pick the right A/R for your application to get the most out of your setup.

  • T3 Inlet and 4 Bolt, 2.5 inch Outlet (Available in .48, .63, or .82 A/R)
  • T25 Inlet, 5 Bolt GT Outlet, with 44 External Waste Gate Port (Available in .72 A/R)

So, if you’re ready to take your ride to a new level, the GTW3476JB is a solid choice. Just make sure to double-check your fitment and grab the right accessories, and you’ll be on your way to some serious horsepower gains.
