If you're on the hunt for a turbo that packs a punch without breaking the bank, the Garrett GTW3684JB (also known as the GTW6262JB) might just be what you need. This journal bearing turbo is designed with a .70 A/R T4 divided turbine housing and a 3" v-band outlet, and it can potentially handle up to 750 HP. That’s some serious power on tap!
Now, let’s get into the nitty-gritty. The compressor wheel has an inducer size of 62.3mm and an exducer size of 84.4mm, which gives you a solid flow capability. The turbine wheel, on the other hand, has an inducer of 71.0mm and an exducer of 61.9mm, with a trim of 76. This combination is what makes the GTW series a great choice for those looking to push their setups without going overboard on cost.
But hold on, before you dive in, there are a few things to keep in mind. This turbo isn't a direct drop-in for the smaller Garrett GT or GTX series. The GTW series has a bulkier CHRA, so you'll need to make sure your setup can accommodate that extra size. Also, the oil return fittings aren't the same as those found on the smaller frames, so be prepared to source some new components.
Speaking of components, here’s a quick list of what you might need to get this turbo up and running:
So if you're ready to take your build to the next level, the Garrett GTW3684JB is a solid choice. Just make sure you’ve got the right setup and components to match. Happy boosting!
