Camshafts, timing parts and head components

Make that engine breethe

The engine is essentially an air pump, which is controlled by valves in the head. Camshafts make the biggest improvement on naturally aspirated engines, and change the characteristics of turbocharged engine drastically. Camshafts alone aren't always enough, so that's why springs, lifters and stronger valves are needed.

The stiffer the head, the more the timing belt is stressed. Making sure nothing will break at 9000rpm is a cheap insurance for an expensive engine.
