This style and design also enables more effective use from the cylinder head Area, and more air volume is moved in to the engine.
This engine was the first inside the series to work with Toyota's dual camshaft method generally known as Significant-Mecha Twin Cam, where by the timing belt drives the exhaust camshaft and the exhaust camshaft then drives the inlet camshaft by using scissor gears.[18][19][twenty] The inlet camshaft acts as a slave camshaft to the exhaust camshaft (the latter acting as a grasp camshaft for that engine), which led into the technique getting unofficially often called the "slave-cam method".

A solution may be to possibly utilize the 16V / Silvertop brackets and pumps or simply simpler just make use of a 4-rib accessory belt as an alternative to the initial five-rib, this allows the belt compensate for the difference by remaining 1 rib offset in between the pulleys.
