The 4A-FE is different within the 4A-GE regarding performance and electric power. Although equally contain the exact same displacement and so are DOHC, they were being optimized for different makes use of. The very first clear change would be the valves, the engine's intake and exhaust valves had been positioned 22.three° apart (as compared to fifty° within the G-Engines). The second is always that it utilized Toyota's Significant-Mecha Twin Cam procedure,[eighteen] where each camshafts are geared together with a singular timing belt driving the exhaust camshaft along with the exhaust camshaft drives the inlet camshaft by means of scissor gears (both equally camshafts about the G-Engine are driven with the timing belts as a substitute).[twenty] Several of the a lot less specifically seen discrepancies ended up compact combustion chamber models with read more intensely shrouded valves, considerably less aggressive camshaft profiles, a cast crankshaft (rather than a cast crankshaft during the 4A-GE), ports of a little cross sectional region, a really restrictive ingestion manifold with extensive runners joined to a small displacement plenum along with other adjustments.

Although this go over was also utilized on early AE92s with the main-era 4A-GZE, The dearth of AFM and its subsequent alternative with MAP inside the afterwards AE92s helps make this technology very easily recognizable.

Toyota developed the engine for performance; the valve angle was a comparatively extensive 50 levels, which at the time was thought for being ideal for high ability creation.[27] These days, lots of present day higher-revving engines use narrower valve angles at all over 20 to twenty five levels, which allows for a far more smaller and compact cylinder head style and design to be used which is now believed being perfect for large-revving engines with superior distinct power outputs.
