The Nissan 200SX S14 and S14a models come equipped with a range of engines and performance capabilities, with one of the most notable differences being in their power output. Both the S14 and S14a were available with a 2.0-liter turbocharged engine, but the S14a had a more powerful version with a revised turbo setup and additional performance enhancements.
The S14 was available with a naturally aspirated 2.4-liter four-cylinder engine that produces 155 horsepower and 160 lb-ft of torque.

Overall, the S14a offers superior performance and acceleration compared to the S14, due to its more powerful engine, improved braking, suspension and reinforced rear subframe. However, the S14 is still a reliable and fun-to-drive car, especially for those who prefer a naturally aspirated engine or a more understated appearance. Both models have their own unique characteristics and driving experiences, and the choice between the two ultimately comes down to personal preference.
Other Differences
While the exterior design, interior design, and engine and performance are the most significant differences between the S14 and S14a, there are a few other details that set these two models apart. For example, the S14a had a wider front track and a slightly longer wheelbase, which improved stability and handling. It also featured larger brakes and a stronger clutch, which were necessary to handle the increased power of the turbocharged engine.
Additionally, the S14a had some minor updates to the suspension and chassis that improved overall performance and handling. For example, the rear subframe was reinforced, and the steering rack was revised to provide more responsive and precise steering. These updates made the S14a an even more capable and engaging sports car than the S14.
