Acura stepped into the market in 2004 with the first generation TSX, positioning it as a luxury sedan that would nicely fit alongside their existing TL and RL models. Interestingly, the TSX wasn’t just any Accord; it was based on the European Accord, a model designed to challenge established German luxury sedans like the Audi A4 and BMW 3 Series. To truly compete in this segment, Acura equipped the TSX with a sophisticated multilink rear suspension and a double-wishbone front suspension setup. This engineering choice contributed significantly to the car’s sporty and engaging driving dynamics, setting it apart from typical sedans. Furthermore, the TSX came packed with electronic driver aids, including traction control, Vehicle Stability Assist (VSA), and an anti-lock braking system (ABS), enhancing both safety and performance.
Beneath the hood of the Acura TSX resided a 2.4-liter four-cylinder K24 engine. This engine delivered a respectable 200 horsepower at 6,800 rpm and 166 lb-ft of torque at 4,500 rpm. Drivers had the choice between a six-speed manual transmission for a more engaging experience or a five-speed automatic for smoother cruising. Power was directed to the front wheels. Acura’s implementation of i-VTEC technology played a crucial role in ensuring the TSX boasted a broad and readily accessible powerband, extending all the way to its 7,100 rpm redline. While these figures might not seem groundbreaking by today’s high-performance standards, the K24 engine is widely recognized as an excellent platform for tuning and readily accepts bolt-on performance modifications. Its robust bottom end allows it to reliably handle internal upgrades such as lighter connecting rods, low-compression pistons, and a stronger crankshaft, making it a strong base for building a potent street racing car.
For those looking to enhance the TSX’s power output with bolt-on components, a range of modifications are available. Consider upgrading to high-flow fuel injectors to supply more fuel for increased power, and a performance exhaust system to improve exhaust flow and add a more aggressive sound. A larger throttle body can increase air intake, while a cold air intake system ensures cooler, denser air reaches the engine. An ECU tune is essential to optimize the engine management system for these modifications, and performance camshafts can further enhance engine breathing. For enthusiasts seeking significant power gains, forced induction systems like turbochargers or superchargers can dramatically increase horsepower and torque, transforming the TSX into a true street racing machine. With these strategic enhancements, the Acura TSX can achieve quicker acceleration and a more menacing engine note, solidifying its potential as a compelling choice for a street racing car project.
