At its core, the GR Yaris boasts a turbocharged three-cylinder engine generating a respectable 268 horsepower. However, for those seeking an adrenaline rush beyond the stock configuration, tuners offer solutions to extract more power. In this particular case, a heavily modified version of the "G16E-GTS" engine now delivers an astonishing 530 horsepower on pump gas. If that's not impressive enough, the engine can run on ethanol, though it currently produces a "mere" 457 horsepower at the wheels due to limitations imposed by a small wastegate.

The journey to achieve this incredible power involved a meticulous process of trial and error. The fully forged engine has been installed and removed from the GR Yaris a remarkable five times as the owner pursued the goal of extracting more power from the compact three-cylinder unit. Despite the challenges encountered with E85, the owner remains optimistic, estimating the potential for a remarkable 660 horsepower with additional modifications.

The transformation of the GR Yaris into a high-performance powerhouse was orchestrated by SRD Tuning. The tuner utilized a Plusar turbocharger to push the limits of the tiny three-cylinder engine. However, in the world of project cars, the pursuit of perfection is never truly complete.

Even with 530 horsepower under the hood, the owner envisions further enhancements for their hot hatch. Plans include installing a sequential gearbox, implementing a custom suspension setup, and widening the stance of the vehicle with new wheels to complement the existing widebody kit. These upgrades will undoubtedly elevate the driving experience and handling capabilities of this already formidable GR Yaris.

The pursuit of automotive excellence comes at a price, and in this case, the owner has invested a staggering £130,000 (approximately $164,000) to bring the GR Yaris to its current state of high-performance glory. The commitment to pushing the limits and crafting a truly unique driving experience showcases the passion and dedication of car enthusiasts who refuse to settle for the ordinary.

The modified Toyota GR Yaris, with its 530 horsepower and $164,000 in upgrades, stands as a testament to the incredible potential hidden within compact platforms. This project not only showcases the engineering prowess of SRD Tuning but also highlights the insatiable desire of car enthusiasts to push boundaries and redefine what is possible in the world of high-performance automobiles. As the owner continues to pursue additional upgrades, the modified GR Yaris is poised to remain a symbol of innovation and a source of inspiration for automotive enthusiasts worldwide.
