Inside the Nairobi Workshop Building East Africa’s Fastest

Bukemersanacokyakisir – Kenya’s underground motorsport culture continues growing rapidly, and one workshop in Nairobi has become one of the most talked-about names in the scene. Rupal Racing, founded by brothers Karan and Simar Rupal, is now known for building some of the fastest Subaru Imprezas in East Africa. What started as a backyard passion project has evolved into a respected performance garage specializing in drag racing monsters with massive horsepower figures. Through custom fabrication, engine building, and relentless experimentation, the Rupal brothers are helping push Kenya’s motorsport community into a new era of speed and performance.

Rupal Racing Began From a Backyard Passion Project

The story of Rupal Racing started long before the workshop became famous within Kenya’s growing racing community. Karan and Simar originally built their own cars in the backyard because they did not yet own a professional garage. During that period, the brothers entered local racing events under the Rupal Racing name, which slowly gained recognition among enthusiasts. Eventually, the demand for their work increased enough for them to establish an official workshop in Nairobi’s industrial district. Today, the garage has become one of the most recognizable tuning shops in the country.

Subaru Culture Has Deep Roots in Kenya

Subaru’s popularity in Kenya is closely connected to the country’s long history with rally racing. For decades, the rivalry between Subaru Imprezas and Mitsubishi Evos shaped the local performance car culture. According to Karan Rupal, many enthusiasts who grew up during the late 1990s and early 2000s became obsessed with those rally legends. That nostalgia still influences the scene today, with first and second-generation Imprezas remaining highly respected among Kenyan tuners and racers. Because of that legacy, Subaru continues dominating many grassroots motorsport events across the country.

Drag Racing Has Become Increasingly Popular

Although Kenya is traditionally associated with rally racing, drag racing and time attack events are becoming much more common. Karan explained that several major clubs now organize competitions throughout the year, creating a busy motorsport calendar for local racers. Rupal Racing mainly focuses on building cars for straight-line speed rather than circuit performance. As a result, most of their workshop projects prioritize massive turbochargers, lightweight body modifications, and extreme horsepower setups designed specifically for drag racing competition.

Modern Competition Forced Builders to Go Bigger

The Kenyan tuning scene has changed dramatically over the past decade. Previously, many performance cars remained relatively close to factory specification with only minor turbo upgrades or intercooler modifications. However, increasing imports of newer sports cars transformed the competitive landscape completely. Kenya’s import regulations allow vehicles less than seven years old into the country, leading to the arrival of powerful six-cylinder and eight-cylinder machines. Eventually, one Nissan GT-R producing around 1,500bhp raised the standard for everyone in the local drag racing scene.

Karan’s GC8 Subaru Produces Around 900bhp

Among all the projects at Rupal Racing, Karan’s personal Subaru Impreza remains the workshop’s most extreme creation. The heavily modified GC8 Impreza uses a fully built EJ25 boxer engine bored out from the original 2.0-liter configuration. Running approximately 45psi of boost pressure on E85 fuel, the car now produces around 900bhp. Additionally, the workshop performs almost all fabrication and engineering work in-house, including bodywork, turbo systems, wiring, and exhaust construction. This level of craftsmanship has helped Rupal Racing gain respect far beyond Kenya’s borders.

Lightweight Modifications Improve Drag Racing Performance

To maximize performance, Karan’s Subaru underwent an extensive lightweight transformation. The car now features custom fiberglass body panels, plastic windows, and a completely stripped interior to reduce overall mass. Even more impressively, the workshop recently converted the Impreza into a two-door coupe using custom fabrication techniques. The car currently weighs around 1,200 kilograms, creating an incredible power-to-weight ratio for drag racing. Furthermore, the turbocharger setup became so large that engineers decided to mount part of the system behind one of the headlights.

Kenya’s Motorsport Infrastructure Still Faces Challenges

Despite the rapid growth of Kenya’s tuning culture, motorsport infrastructure remains limited compared to larger racing nations. Karan explained that many events currently take place on temporarily closed public roads because the country lacks dedicated drag strips and modern racing circuits. Although local authorities sometimes provide permits for racing events, the conditions are far from ideal for high-performance machines. Consequently, many builders believe the scene could develop even faster if investors supported professional motorsport facilities across the country.

Rupal Racing Builds More Than Just Subaru Engines

While Subaru Imprezas remain the workshop’s specialty, Rupal Racing also performs maintenance and performance upgrades on various other vehicles. The team handles turbocharging projects, CVT rebuilds, custom exhaust fabrication, and complete engine overhauls for multiple brands. However, first and second-generation Subaru Imprezas still dominate the garage floor because of their strong connection to Kenyan motorsport culture. This consistent demand keeps the workshop deeply connected to the golden era of Japanese rally-inspired performance cars.

The Brothers Continue Expanding Their Ambitious Projects

Karan and Simar continue pushing their workshop toward increasingly ambitious creations. In addition to the famous 900bhp GC8, the brothers are currently building another unique Subaru project featuring a custom two-door estate body style paired with another turbocharged EJ25 engine. According to Karan, sourcing rare components such as intercoolers and body parts remains one of the biggest challenges. Nevertheless, the brothers remain committed to finishing the project and expanding the reputation of Kenyan performance engineering.

East Africa’s Motorsport Future Looks Extremely Promising

The rise of workshops like Rupal Racing demonstrates how quickly East Africa’s motorsport culture is evolving. What once began as a small underground community now includes increasingly advanced builds capable of competing with serious international performance cars. Enthusiasts across Kenya continue investing in bigger power figures, more advanced engineering, and professional-level fabrication. If modern racing infrastructure eventually develops within the region, Kenya could become one of Africa’s most exciting destinations for grassroots motorsport and high-performance tuning culture.
