Engine Displacement Calculator

One liter equals 1,000 cubic centimeters (cc). So a 2,000 cc engine is a 2.0-liter engine, a 3,500 cc engine is a 3.5-liter engine. Both units measure the same thing - total swept volume. Cubic centimeters are preferred for smaller engines (motorcycles, small cars); liters for automotive marketing.

Larger displacement means more air-fuel mixture per combustion cycle, which generally means more power at the same RPM. However, the relationship is not direct: engine design, compression ratio, cylinder head flow, camshaft timing, and forced induction all affect output. A turbocharged 2.0L can easily out-power a naturally aspirated 3.5L.

A stroker kit replaces the crankshaft with one that has a longer stroke (piston travel), increasing displacement without changing the bore size. For example, a 350 cubic inch engine with a longer stroke becomes a 383 or 400 ci. This is one of the most cost-effective ways to increase displacement in a block that already fits the car.

They do not always - those are marketing badges rounded from the actual calculated displacement. A 1,998 cc engine is called a 2.0L; a 5,654 cc engine is called a 5.7L. The actual displacement depends on the exact bore and stroke dimensions chosen during engineering for performance, emissions, and manufacturing reasons.
