The key to maximizing power output is to optimize the engine's breathing (intake and exhaust), fuel supply, and ignition timing.
High-performance cams, ported heads, high-compression pistons, and a well-tuned exhaust system can significantly boost power output. To fuel the engine, larger carburetors or fuel injection systems may be necessary. Upgrading the ignition system with higher-energy coils, spark plugs, and wires can also improve performance.
Other modifications, such as lightweight bodywork and suspension upgrades, can further enhance the T500's performance and handling.
However, it's essential to note that highly tuned engines may have reduced reliability, increased fuel consumption, and compromised street legality, so careful planning and consideration should be given before embarking on such modifications.
