If you're diving into the world of high-performance turbocharging, you’ll want to check out the Garrett SFI approved stainless steel v-band inlet and outlet turbine housing. This isn’t just any turbine housing; it’s designed specifically for the GT55 and GTX55 series turbochargers, and trust me, it delivers when it comes to both flow and safety.
One of the standout features here is the 1.24 A/R turbine housing, which is perfect for those pushing serious horsepower. Whether you’re hitting the track or just looking to boost your street ride, this housing is built to handle the heat. The construction is solid—made from stainless steel, it’s not just durable but also resistant to the elements, which is a big plus if you’re out there putting your vehicle through its paces.
Now, let’s talk safety. Garrett has gone the extra mile by including two 3/8” Grade 5 cross bolts installed at right angles in the turbine housing outlet. This might seem like a small detail, but it’s a game-changer. In the unfortunate event of a catastrophic failure, these bolts help prevent material escape, giving everyone—drivers, crew, and spectators—a bit more peace of mind. Not many turbo manufacturers offer this level of safety as standard, especially on non-SFI certified housings.
As for compatibility, this housing works seamlessly with the GTX5533R Gen I and Gen II GTX5544R models, so if you’re already invested in the Garrett ecosystem, you’re in good hands. Plus, you’ve got options with both 1.24 A/R and 1.40 A/R, depending on how you want to set up your setup.
When it comes to installation, you’ll appreciate the threaded bosses for attachment points, making it easier to get everything lined up just right. The 4.25” v-band inlet and 5” v-band outlet are designed for a snug fit, ensuring that you’re maximizing flow without any leaks.
For those of you looking to complete your setup, don’t forget about the flanges and clamps. You’ll need the V-Band Outlet Flange (Code: ATP-FLS-382) and the V-Band Outlet Clamp (CLC-CLA-022) for your downpipe, plus the V-Band Inlet Flange (Code: ATP-FLS-225) and Inlet Clamp (CLC-CLA-029) for your manifold. These components are essential for a secure and reliable connection.
In short, if you’re serious about performance and safety, the Garrett SFI stainless steel turbine housing is worth considering. It’s built for enthusiasts who demand the best, and it’s ready to take your turbo setup to the next level.
