As you look to extract every ounce of potential from the legendary 3.8L turbocharged V6 in your 1986 to1987 Buick Grand National or T-Type, a torque converter upgrade from Yank Performance remains the definitive solution for reducing lag. Widely recognized as the best torque converter brand for GM enthusiasts, we utilize 9.5-inch billet steel covers and furnace-brazed internals to ensure maximum durability under high-boost conditions. These performance torque converters are precision-engineered to eliminate the sluggish factory launch, allowing your turbocharger to reach its peak power band almost instantly.

The defining characteristics of our Turbo Buick lineup include solid billet lock-up clutches and one-piece roller-burnished hubs that provide smooth streetability without sacrificing track performance. Whether you are running a stock turbo or a highly modified setup, these units multiply torque more efficiently to significantly lower your 60-foot times. Each converter is built to handle up to 650 RWHP, maintaining reliable operation and consistent fluid temperatures even during repeated high-stress launches. Order today.
