Toyota’s sport-type twin-cam engines utilize a DOHC 4-valve per-cylinder configuration, but it is a very simple and reliable one. The camshafts act directly on the valves (through the shim and follower) using the same principle that was employed on Salmson racing engines of 1927. The increase intake and exhaust valve area of a four-valve design improves the volumetric efficiency, and the lighter weight of the valve train allows higher-revs. As Toyota’s sports-type engines should be, these engines are designed and built for high output and quick response.
These engine are one of the few which can reach 11000Rpm and at that stage the sound of the engine is music to my ears haha......even though nw is the modern age but i still like it old school cause newer cars have too much electronics and we can't really enjoy the fel of the road :D
