Frequently Asked Questions
How do I pick the right drain size?
Match the bolt spacing (35mm, 65mm, or 100mm) and AN size (10AN or 12AN) to your turbo's oil drain pattern and frame size — small, mid, or large.
What is the turbo speed sensor plug for?
It plugs the speed sensor port on turbos that don't use a speed sensor.
BSI Inc. Billet Turbo Drains – The Ultimate Solution for Leak-Free Performance
When it comes to turbocharger reliability and efficiency, every component matters—including the turbo drain. At BSI Inc., we’ve engineered billet turbo drains that solve the common issues found in standard drains, ensuring superior durability, easy installation, and leak-free performance.
Built for Extreme Conditions
Our turbo drains are machined from a 26XX series forged extrusion, specifically chosen for its high resistance to stress cracking. Unlike 6061 extended drains, which can weaken over time due to continuous heat cycles, our design ensures long-term durability and reliability—even in the hottest locations of your engine bay.
No More Leaks – Captured High-Temp O-Ring Seal
Say goodbye to paper gaskets, RTV messes, and cheap, unreliable China drains. Our captured high-temp O-ring seal eliminates the need for RTV and traditional gaskets, ensuring a secure, leak-free fit that won’t fall out during installation. Using RTV on an oil drain is bad practice, and we’ve developed a better solution that prevents headaches during installation and operation.
Perfect Fit for Any Turbo Setup
We designed our billet turbo drains to fit a wide range of small, mid, and large-frame turbochargers, making them versatile and easy to integrate into any build. Available in 35mm, 65mm, and 100mm lengths, our drains accommodate various mounting locations and plumbing setups, ensuring a seamless fit for your specific application.
Easier Installation, Maximum Performance
We’ve worked hard to eliminate as many small installation issues as possible, making turbo drain installation hassle-free. The result? A precision-machined, high-quality turbo drain that enhances oil drainage, reduces failure points, and withstands extreme conditions.
