This engine was the 1st within the collection to work with Toyota's twin camshaft system often known as Substantial-Mecha Twin Cam, exactly where the timing belt drives the exhaust camshaft plus the exhaust camshaft then drives the inlet camshaft by using scissor gears.[eighteen][19][twenty] The inlet camshaft acts as a slave camshaft to the exhaust camshaft (the latter performing being a grasp camshaft to the engine), which led on the program becoming unofficially often known as the "slave-cam system".
The very first-technology 4A-GE is nicknamed the "bigport" engine as it had ingestion ports of an incredibly huge cross-sectional area. Although the port cross-section was well suited for an incredibly very modified engine at very higher engine speeds, it caused a considerable fall in lower-end torque mainly because of the lowered air speeds at those rpm. To compensate for that decreased air speed, the initial-technology engines provided the T-VIS feature, where dual intake runners are equipped with butterfly valves that opened at somewhere around 4,200 rpm. The effect is always that at lower rpm (once the airspeed would normally be slow) four from the 8 runners are closed, which forces the engine to attract in all its air through 50 percent the runners in the manifold.

An answer may be to both utilize the 16V / Silvertop brackets and pumps or perhaps less complicated just utilize a 4-rib accessory belt in place of the original 5-rib, this allows the belt compensate for the real difference by remaining a single rib offset involving the pulleys.
This engine is not really almost figures; it’s regarding the driving expertise. The 4AGE is known for its responsiveness and agility, making it a favorite among the tuners and racers alike. Engine Variants
This is one of very few Toyota ignitions which might be marginal. Colder plugs should be made use of with any update. For carburetor Geared up 4AGs the distributor needs to supplemented that has a timing controller, MSD 6A, along with a coil.
