If you’re looking to crank up the performance of your turbo setup, the T4 open (undivided) turbine housing for the Garrett GTW3476R is a solid choice. I’ve had my hands on this piece, and let me tell you, it’s built for those who want to push their ride to the next level. With a .82 A/R and a 3-inch GT V-Band exit, this housing is designed to maximize flow and efficiency, which translates to quicker spool times and a more responsive throttle.
One of the things I appreciate about this turbine housing is its versatility. Whether you’re running ball bearings or journal bearings, it’s compatible with both, making it a great option for various setups. The construction feels robust, and you can tell it’s made to withstand the rigors of high-performance driving. Plus, the open design helps reduce back pressure, which is a game-changer for anyone serious about their turbo performance.
Now, if you’re diving into this upgrade, you’ll want to grab the flange and clamp set for the V-Band outlet on the down-pipe side (Product Code: CLC-CLA-052). It’s a small addition that makes a big difference in ensuring a tight seal and preventing any leaks that could rob you of power.
All in all, the ATP-HSG-654 turbo housing is a solid investment if you're looking to boost your Garrett GTW3476R setup. It’s straightforward, effective, and delivers the kind of performance that’ll put a smile on your face every time you hit the gas.
