By reducing the dynamic spring constant in the high frequency range, the cylindrically shaped liquid filled compound mount reduced vibration and noise.   Your link has been automatically embedded. It was a compact DOHC engine for good economy and good driving characteristics. At the same time, one of the five original engine mounts in the Corolla was dropped, leaving four; but the right-side engine mount were revised, to a cylindrical, shaft-type liquid-filled compound type to reduce vibration and noise.

There was originally a cold-start injector in the 4A-FE, but this was eliminated in 1993. • Privacy/Terms In addition, a brace between the head and throttle body was added to reduce vibration. only 200cc difference but massive response difference. The throttle position sensor went from being a point type to a linear type; the oxygen sensor continued without a heater, but a second oxygen sensor was added to check up on the first one; the rpm sensor was chagned form a single pickup coil with 24 teeth to dual four-tooth coils; and the crankshaft position sensor was changed from a single coil with four teeth to a single-tooth coil. If you have an account, sign in now to post with your account. 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). 4a has peak torque at 4800rpm and peak power at 5800. if you get a jap 4afe ecu it will increase revs to 6000 and add an extra 10nm and 10hp. 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. Hi guys! The torque curve was fairly flat, with a steep, linear horsepower curve. 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. More Toyota engines at toyoland • Camry • RAV4 • Corollas at Corolland, Home i wonder what the redlines on both of these engines are ?? 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. For the right-hand engine mount, newly designed: The newly-developed liquid filled compound mount had an insulator filled with a fluid. Paste as plain text instead, × In addition to a knock sensor, the 7A-FE had a torque management feature which cut torque while the automatic transmission shifted to minimize harshness. Just wanted to know which of these accelerates the best?? Clear editor. You can find them in 93-96 corolla's. 8 7afe engine installed and running Ch * A 7afe is not just a stroked 4afe, the engines are completly different internally, Pistons are different, Cam profiles are different, Valves are different sizes, 7afe uses a 2 piece oil pan, also the cooling system is different and more efficent on the 7afe then the 4afe's, 7afes cooling system promotes cooler intake temps for better knock resistance and increased volumetric efficency. I am in need of a 7afe engine I found what I thought was a 7afe in a 96 corolla it looks exactly like the 7afe I took out of my celica. (adsbygoogle = window.adsbygoogle || []).push({}); The shaft type mount was rotated 90° from the previous mounting position. Site Contents. Intake valve opening remained at 6° BTDC as it had been in 1992. Display as a link instead, × NIKICH, This causes the rubber in the mount's shear direction to be the soft direction, thus reducing engine noise and booming noise. My 4afe has aftermarket ecu so i set the revlimit at 8000. never ran the engine with a stock ecu. Any one kindly tell me which engine has better fuel economy .
