Dominic Maguire’s 2003 Acura RSX boasts a unique turbocharged setup, thanks to a resourceful approach and the expertise of H-Car Engine Dyno Tuning in San Antonio, Texas. This build showcases the potential for impressive performance gains with careful planning and professional tuning.
A Diesel Turbo on a Gas Engine?
Maguire’s journey began with a chance encounter, leading him to acquire a Banks Sidewinder turbocharger originally designed for a 7.3-liter Ford diesel engine. Recognizing the potential, despite the significant size difference compared to the Acura’s 2.0-liter gasoline engine, he sourced additional components like an intercooler, wastegate, and blow-off valve.
The substantial size difference between the turbo and the engine results in noticeable boost lag, with power surging around 4,000 RPM. However, once engaged, the turbo delivers significant power. Maguire emphasizes the durability of the setup, stating, “This turbo is awesome. I’ve thrown everything at this thing, and it just won’t die. Such a great design.”
Hondata K-Pro and Expert Tuning
While opting for used parts for much of the build, Maguire prioritized engine management. He chose Hondata’s K-Series Programmable ECM (K-Pro) and entrusted the tuning to H-Car Engine Dyno Tuning in San Antonio, Texas. This professional tuning ensures the engine operates safely and efficiently with the significant modifications.
Future Plans: E85 and 500 HP
Maguire’s project is ongoing, with plans to incorporate an E85 flex-fuel system, increase boost pressure, and further refine the tune at H-Car Engine Dyno Tuning. His ultimate goal is to achieve 500 horsepower. This ambitious target demonstrates the potential of the platform and the importance of professional tuning in maximizing performance.
This unique Acura RSX build highlights the ingenuity and dedication of car enthusiasts. The crucial role of H-Car Engine Dyno Tuning in harnessing the power of the unconventional turbo setup underscores the importance of expert tuning in achieving performance goals while maintaining reliability.
