There’s an 800-Horsepower, Dual-Turbo Buick V6 That Requires a Fresh Owner

[ad_1]

The turbocharged, 3.8-liter Buick V6 has a storied reputation, and enthusiasts worldwide hold it in high regard. Even those who typically favor large engine sizes acknowledge the prowess of this boosted six-cylinder powerhouse. It outshined larger and louder engines during its prime in the Grand National and GNX, producing 276 horsepower in its most potent iteration. While impressive back then, it now pales in comparison to V6 muscle cars and even the Buick Enclave SUV with its 310-hp output. Nevertheless, an all-aluminum version of this engine boasting a remarkable 800 hp is currently available for purchase on Phoenix’s Craigslist.

If you’re interested, you’ll need $18,000 to make it yours.

Notably, this engine was a collaborative effort between Duttweiler Performance and TA Performance, as highlighted by Hagerty . Their partnership resulted in a power plant that once powered the current seller’s sand buggy. TA Performance is renowned for its expertise in tuning Buick engines and its advancements in aluminum heads and blocks, with this engine showcasing some of their finest craftsmanship. Additionally, enhancements to the engine’s cooling system further amplify its capacity to handle significant horsepower.

The bore and stroke of this engine have been increased to 3.940 and 3.625 inches, respectively, resulting in a displacement of 4.3 liters. A Crower billet crankshaft and CP pistons play a vital role in enhancing power, while the twin turbochargers deliver a surge of air. This engine boasts two tuning stages, the first providing 600 hp at the wheels with 15 to 18 pounds of boost. Crank it up to the more aggressive tune, and you’ll be experiencing a heart-pounding 795 horsepower on 110-octane fuel with 29 pounds of boost.

This engine previously gained recognition in Hot Rod when it was newly built back in 2006. As stated in the article, the build cost totaled $40,000, with approximately $25,000 allocated solely to parts. This expenditure is substantial, especially when compared to the original cost of a Buick Grand National, even after adjusting for inflation using inflation calculations.

The current owner is replacing the expensive V6 with a more cost-effective and reliable LS2 V8, capable of delivering similar power outputs. While their decision is sensible, one can only hope that this exceptional engine finds a new home in an equally extraordinary project car.
