The Originals Since 2014
In 2014, the team at Boost Lab, Inc. set out to solve a problem: how do you give a modern turbocharger the aggressive jet spool and whistle sound that made the old HKS T51R series legendary, without tracking down a discontinued turbo? The answer became the T51R Billet Compressor Cover Modification.
We developed a precision-machined billet anti-surge insert that replicates the inlet geometry responsible for the iconic T51R sound. The result is a turbocharger that spools with the unmistakable jet-like whistle that performance enthusiasts have chased for decades, on virtually any compatible turbo.
Since its creation, the T51R mod has become a viral sensation in the global turbocharger community. Videos of the sound have spread across YouTube, Instagram, and forums worldwide, and demand has grown every year since. Boost Lab, Inc. are the originators of the T51R mod. Every shop offering a version of this modification is following a path we blazed over a decade ago.
