The Toyota 1.8 litre engine develops 132 horsepower at 6,000 RPM and 128 foot-pounds of torque. The engine uses double overhead cams and sequential fuel injection which will support an increase in horsepower. There are four ways to produce more power. They vary in price and results. A turbocharger can be added or a supercharger, or nitrous oxide injection. Or, consider swapping parts inside the engine. Getting more punch from an engine of less than two litres requires money and effort, but it can be accomplished without losing reliability.

Investigate the use of a turbocharger. The turbo uses exhaust gases to spin a fan which pushes air into the engine under pressure. Turbochargers are relatively inexpensive but have the disadvantage of being useful only in the mid to high engine speed range. Some turbochargers produce a jarring effect when they join the effort to produce horsepower. The use of two turbochargers will smooth out the power delivery, but that becomes expensive. Turbochargers add fifty per cent or more horsepower.
Look at nitrous oxide injection. Nitrous oxide contains oxygen in a form that can be used in the 1.8 litre engine. The nitrous isn't used until the driver flips a switch so the engine works normally most of the time. Nitrous can produce dramatic results and offers cost savings, but it is difficult to control and can damage the engine if used in the wrong concentration.
Change parts within the engine. The Toyota owner can increase the horsepower of a 1.8 litre engine from 132 to 155 horsepower by installing headers and a free-flow exhaust system and a new ram induction kit. This approach has the advantage of retaining the reliability of the 1.8 litre engine and increasing gas mileage as well as performance.
Take a hopeful look at supercharging. The supercharger sits on top of the 1.8 litre engine and feeds increased air/fuel mixture into the combustion chambers. It uses power from the engine to operate, resulting in a decrease in output. The supercharger makes up for this loss and then some, developing a net increase in horsepower of fifty per cent or more. The increased power is felt throughout the power band, especially in the lower range where the 1.8 litre engine needs the help.
