If you're looking to push your ride to the next level, the GTW3476JB turbo is a solid choice. This isn’t just any turbo; it’s a 58mm journal bearing powerhouse that can potentially deliver up to 700 horsepower. The .82 A/R turbine housing is designed for serious performance, and the T3 undivided inlet makes installation straightforward, which is always a bonus when you're knee-deep in a build.
What really sets this turbo apart is its size and flow capabilities. The compressor wheel inducer measures in at 58.3mm, while the exducer is a hefty 76.4mm. That’s some serious airflow right there. The turbine wheel also packs a punch with a 65.0mm inducer and a 56.6mm exducer, which means you’re getting a nice balance of power and efficiency. It’s a great upgrade if you’re coming from the smaller Garrett GT or GTX series, but just keep in mind that this isn’t a direct drop-in replacement. The GTW series has a bulkier bearing housing, so you’ll need to plan for that in your setup.
One thing to note is that the oil fittings are different from what you might be used to with the smaller Garrett turbos. You’ll need to grab the right flanges and gaskets to make sure everything fits snugly. For the oil feed, check out the ATP-FLA-041 flange and the ATP-GSK-026 gasket. For the drain side, you’ll want the ATP-FLA-042 and ATP-GSK-027. Don't forget to grab some 8mm x 1.25 bolts (MIA-FST-034) to keep everything secure.
As for the turbine housing components, you're looking at a T3 inlet flange (ATP-FLS-038) and gasket (GRT-GSK-005), plus a GT 3" V-band flange for the downpipe (ATP-FLS-246) and a matching clamp (CLC-CLA-048). These parts are essential for ensuring your turbo operates at its best and keeps everything leak-free.
In short, the GTW3476JB is a fantastic turbo for those ready to unleash some serious horsepower. It’s built to perform and designed with the enthusiast in mind. If you’ve got the right setup and a thirst for power, this turbo is definitely worth considering.
