Also of Be aware would be that the Silvertop piston is lighter at 308 grams devoid of rings or maybe a gudgeon pin set up in comparison to the 315.5g from the blacktop. The Blacktop does have a top-quality gudgeon pin layout in that it's got countersunk finishes which give it a small 3g edge bringing the weight variance slightly nearer. The gudgeon pins them self are easily interchangeable.

The 4A-FE differs through the 4A-GE regarding functionality and energy. Whilst equally possess the similar displacement and therefore are DOHC, they were being optimized for different takes advantage of. The primary obvious variation would be the valves, the engine's consumption and exhaust valves were being placed 22.3° aside (in comparison to fifty° in the G-Engines). The second is the fact it employed Toyota's Large-Mecha Twin Cam system,[eighteen] exactly where both of those camshafts are geared along with the consumption camshaft being driven off from the exhaust camshaft through scissor gears (equally camshafts to the G-Engine are driven because of the timing belts in its place).[20] A number of the less specifically noticeable distinctions were compact combustion chamber styles with heavily shrouded valves, significantly less intense camshaft profiles, a Forged crankshaft (rather than a forged crankshaft within the 4A-GE), ports of a little cross sectional spot, an extremely restrictive ingestion manifold with long runners joined to a small displacement plenum along with other alterations.
