7afe vs 4afe

Will I notice a big loss of power? u will have a great time with a mildly tuned smallport... i know i do ^__^ ke ke. 7afe Vs 4afe That 7AFE you mention, I remember reading on this site that it has a 20v head swapped onto it, in effect being actually what the call a 7AGE its not a Toyota engine but by mating the 4AGE head and 7AFE bottom they came up with this name. You can probably get away with swapping a lot of those parts but you will need a new ECU and probably need to rewire some stuff. The fuel injection system was changed from a somewhat inefficient all-firing-at-once system to a more modern two-at-a-time system, now just one step away from sequential injection. Cutout may be around 7600 but definitely not redline. By using this cooling sequence, the intake air temperature is reduced and knocking resistance and volumetric efficiency are improved. Come join the discussion about restorations, performance, modifications, classifieds, troubleshooting, maintenance, and more! A test mode function was added; in the 7A-FE engine, a knocking correction function using a knock sensor was also added. Intake valve opening remained at 6° BTDC as it had been in 1992. × The cooling system reached the bottom of the intake port first to reduce intake air temperature, improving knock resistance and efficiency.

The 7A engine series was essentially the same engine, stroked for higher displacement (1.8 liters) and better torque. i wonder if the 7afe has a lower redline because of extra stroke ?? VerticalScope Inc., 111 Peter, Suite 901, Toronto, Ontario, M5V 2H1, Canada. If I get this engine will it fit in my 94 celica st will my distributor, manifold, fuel injection system fit this engine will my ecu function proper. (adsbygoogle = window.adsbygoogle || []).push({}); The shaft type mount was rotated 90° from the previous mounting position. The 7A-FE boasted an extra 10 horsepower and 15 lb-ft of torque, engaging at a lower rpm (110 hp in California); in metric terms, it pushed out 82 kW and 156 Nm. The shape of the exhaust manifold was changed to match the newly-adopted WU-TWC manifold converter. The intake diameter was increased from 30.0 to 31.0 mm, the exhaust kept the same size at 24.5 mm, and the lift increased from 6.6 to 7.6 (both intake and exhaust). The torque curve was fairly flat, with a steep, linear horsepower curve. Also, the 7AFE in the AE112 has slightly different outputs to the AE102 one, the peak power/torque rpms are different, as well as the ECU mapping and exhaust manifolds being different.
