Hey car enthusiasts! Ever dreamed of blending classic muscle with modern performance? Then you've probably heard whispers of the Buick Grand National Pro Touring. This isn't your grandpa's Buick; it's a beast reborn, combining the iconic Grand National's menacing looks with upgraded handling, braking, and comfort. Buckle up, because we're diving deep into what makes a Grand National Pro Touring build so special, exploring everything from engine swaps to suspension upgrades and interior refinements.

What is a Buick Grand National Pro Touring?

Okay, let's break it down. The original Buick Grand National, produced in the 1980s, was already a force to be reckoned with. Its turbocharged V6 engine offered impressive performance for its time, making it a favorite among drag racers and street performance enthusiasts. Now, imagine taking that raw power and injecting it with a heavy dose of modern technology. That's essentially what a Pro Touring build achieves.

Pro Touring is all about enhancing a classic car's capabilities to match or exceed those of contemporary sports cars. This means addressing areas where the original Grand National might have fallen short, such as handling, braking, and overall drivability. A Grand National Pro Touring build typically involves upgrades like a more powerful engine (often an LS swap), a modern suspension system, high-performance brakes, and a refined interior with updated technology.

Think of it as a restomod taken to the extreme, focusing not just on aesthetics but also on creating a truly high-performance machine that's equally comfortable on the street and the track. The goal isn't just to make it look good; it's to make it perform like a modern sports car while retaining the classic Grand National's iconic style. This blend of old and new is what makes the Pro Touring Grand National so appealing to enthusiasts.

Key Elements of a Grand National Pro Touring Build

So, what exactly goes into transforming a stock Grand National into a Pro Touring monster? Let's explore the key components that define these builds:

Engine Swaps and Performance Upgrades

While the original turbocharged V6 was impressive in its day, many Pro Touring builds opt for a more modern and potent engine. The LS swap is a popular choice, offering a wide range of power options and readily available aftermarket support. An LS engine can provide significantly more horsepower and torque, transforming the Grand National into a true performance machine. Other popular choices include the LT series engines, offering even more advanced technology and power potential.

Beyond the engine swap, other performance upgrades are crucial. A high-performance fuel system is necessary to support the increased power, along with a custom exhaust system to improve airflow and unleash the engine's full potential. Upgraded turbochargers, intercoolers, and engine management systems can further enhance performance, pushing the Grand National into supercar territory. These upgrades not only increase horsepower but also improve the engine's reliability and efficiency.

Suspension and Handling

The original Grand National's suspension was designed for comfort, not corner carving. To achieve Pro Touring levels of handling, a complete suspension overhaul is essential. This typically involves replacing the stock suspension components with aftermarket coilovers, which allow for adjustable ride height and damping. Upgraded sway bars help reduce body roll, improving the car's stability in corners. Some builders also opt for a complete chassis upgrade, reinforcing the frame and improving overall rigidity.

Modern suspension systems can dramatically improve the Grand National's handling characteristics, making it feel more planted and responsive. Upgraded steering systems, such as rack-and-pinion conversions, can further enhance the driving experience, providing more precise and direct steering feedback. These upgrades transform the Grand National from a straight-line performer into a well-rounded sports car capable of tackling twisty roads with confidence.

Brakes

With all that extra power, you'll need brakes that can keep up. Upgrading to a high-performance braking system is crucial for safety and performance. This typically involves replacing the stock brakes with larger rotors, multi-piston calipers, and high-performance brake pads. These upgrades provide significantly more stopping power and improve brake fade resistance, ensuring consistent performance even under hard use.

Many Pro Touring builds also incorporate modern braking technologies, such as ABS (Anti-lock Braking System) and traction control, to further enhance safety and control. These systems help prevent wheel lockup and maintain traction, allowing the driver to confidently explore the car's performance limits. Upgraded brake lines and master cylinders ensure optimal brake feel and responsiveness.

Wheels and Tires

The right wheels and tires can dramatically improve both the look and performance of a Grand National Pro Touring build. Larger diameter wheels, typically 17 inches or larger, allow for the use of wider, lower-profile tires. These tires provide significantly more grip, improving handling and braking performance. Modern tire compounds offer excellent traction in both dry and wet conditions, making the car more versatile and enjoyable to drive.

Wheel selection is also a matter of personal preference, with many builders opting for classic designs that complement the Grand National's styling. However, modern wheels are often lighter and stronger than their vintage counterparts, further improving performance. The combination of larger wheels and high-performance tires transforms the Grand National's stance and gives it an aggressive, modern look.

Interior and Technology

While performance is the primary focus of a Pro Touring build, comfort and convenience are also important considerations. Many builders choose to upgrade the interior with modern amenities, such as custom seats, air conditioning, and a premium sound system. Digital dashboards and infotainment systems can provide a wealth of information and entertainment, enhancing the driving experience.

Modern touches, such as power windows, power locks, and keyless entry, can also be added to improve the car's usability. The goal is to create an interior that is both comfortable and functional, blending classic style with modern technology. Custom upholstery and trim can further personalize the interior, creating a unique and inviting space.

Popular Engine Choices for Grand National Pro Touring Builds

When it comes to engine swaps, the options are vast, but some choices are more popular than others. Here's a rundown of some of the most common engine choices for Grand National Pro Touring builds:

• LS Engines: As mentioned earlier, the LS engine family is a favorite among Pro Touring builders. These engines are readily available, relatively affordable, and offer a wide range of power options. From the humble LS1 to the fire-breathing LS9, there's an LS engine to suit every budget and performance goal. The aftermarket support for LS engines is also extensive, making it easy to find parts and upgrades.

• LT Engines: The LT series engines, such as the LT1, LT4, and LT5, are the next generation of small-block Chevy engines. These engines offer even more advanced technology and power potential than the LS series. Direct injection, variable valve timing, and advanced engine management systems contribute to improved performance and efficiency. LT engines are a popular choice for those seeking the latest and greatest technology.

• Original Turbocharged V6: Some purists prefer to stick with the original turbocharged V6, albeit with significant upgrades. These builds often involve rebuilding the engine with stronger internals, upgrading the turbocharger, and installing a modern engine management system. While this approach may not yield the same peak horsepower as an LS or LT swap, it preserves the Grand National's original character.
