If you’re on the hunt for a turbo that packs a punch without breaking the bank, the Garrett GTW3684JB 62/62MM Supercore might just be your new best friend. This turbo, also known as the GTW6262JB, is designed for those who crave performance and efficiency. With a potential flow of up to 750 HP, it’s no slouch when it comes to boosting your ride.
Let’s dive into the specs a bit. The compressor wheel has an inducer diameter of 62.3mm and an exducer of 84.4mm, giving you a solid trim of 54. On the turbine side, you’ve got a 71mm inducer and a 61.9mm exducer with a trim of 76. All of this means you’re looking at a turbo that’s not only powerful but also responsive.
One of the standout features is the T04E compressor housing. It comes with a 4-inch inlet and a 2-inch outlet, plus a built-in anti-surge design that’s machined for precision. This is important because it helps keep your boost steady and reliable, especially when you’re pushing the limits.
Now, a heads-up: this isn’t a direct drop-in for the smaller Garrett GT or GTX series turbos. The GTW series is a bit bulkier, so you’ll need to make sure you have the space for it. Plus, the oil return fittings are different, so make sure you’re prepped with the right components. You’ll want to grab the oil feed flange (Product Code: ATP-FLA-041) and gaskets (like ATP-GSK-026 for the feed and ATP-GSK-027 for the drain) to get everything set up properly.
When it comes to turbine housing options, you’ve got a lot of flexibility. Whether you’re looking for a T3 inlet with a 4-bolt or V-band outlet, or even a T4 inlet, there’s an option for you. Just keep in mind the A/R ratios available, ranging from .63 to 1.08, depending on your setup and goals.
In short, if you’re ready to take your ride to the next level with a turbo that’s built for performance and reliability, the Garrett GTW3684JB is worth considering. It’s got the specs to back it up and the potential to turn your car into a powerhouse. Just be ready to put in a little work to get it set up right!
