* 7afes fuel cut off is 6800, mate i used to be there everyday.

The crankshaft and connecting rod specifications were modified to match the longer piston stroke and higher power output of the 7A-FE engine, and the pistons were made more rigid by modifying the oil return from the slits to 8 holes. The shape of the exhaust manifold was changed to match the newly-adopted WU-TWC manifold converter. 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.

There was originally a cold-start injector in the 4A-FE, but this was eliminated in 1993.

This causes the rubber in the mount's shear direction to be the soft direction, thus reducing engine noise and booming noise. 1) 4afe 2) 5afe 3) 7afe For corolla indus 1996 and which engine can easily fit without alteration.

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. Display as a link instead, × Will I notice a big loss of power? The 4A engine series was a 1587 cc (1.6 liter) engine, introduced in 1988, and revised to 4A-FE in 1993; it was mainly used in the Corolla, and was replaced by the ZZ series in the 1998s.The 7A engine series was essentially the same engine, stroked for higher displacement (1.8 liters) and better torque. 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. × Switching to a rotary solenoid-type idle control valve meant that the idle-speed adjusting screw could be eliminated.
A test mode function was added; in the 7A-FE engine, a knocking correction function using a knock sensor was also added. A forum community dedicated to Toyota Celicas owners and enthusiasts.

Discussion Starter • #1 • Mar 10, 2009. I checked the vin and it said that it was a 1.6l and I think that is a 4afe. If you have an account, sign in now to post with your account. In addition, the rubber in the mount's compression direction was in the hard direction, improving the vehicle's drivability. The valve details were also changed to match the improved performance.

i wonder if the 7afe has a lower redline because of extra stroke ??

Cutout may be around 7600 but definitely not redline.

The flow of fluid within the orifice increased the damping coefficient and thus suppressed engine vibration. When the 7A-FE was designed, it was given the same improvements as the 4A-FE, as well as a knock sensor. My 4afe has aftermarket ecu so i set the revlimit at 8000. never ran the engine with a stock ecu.   Your previous content has been restored.   You cannot paste images directly. Cars •

NIKICH, 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. u will have a great time with a mildly tuned smallport... i know i do ^__^ ke ke.

The intake air chamber and intake manifold could now be separated to provide easier access to injectors; an equal-length intake manifold was used to reduce intake air noise; and metal gaskets were used for the intake manifold and intake air chamber gaskets to improve seal performance. Toyota 4A-F and 7A-FE engines: details and photos .

Along with the revamping of the intake system, the two resonators in the air cleaner hose were cut to one. only 200cc difference but massive response difference. Timing was changed so that the intake closed at 38° ABDC instead of 34°, exhaust opened at 42° instead of 37°, and exhaust closed at 2° ATDC instead of 3°. October 22, 2007 in Corolla / Corolla Sportivo Club.

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.

In California trim, it produced 100 hp (86 kW). VerticalScope Inc., 111 Peter, Suite 901, Toronto, Ontario, M5V 2H1, Canada.

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.

I think i have a 2nd gen 4AFE by accident. The damping coefficient in the low frequency range was made larger, thus improving drivability and riding comfort.

The 7A engine series was essentially the same engine, stroked for higher displacement (1.8 liters) and better torque. The 4A-FE, by 1993, was producing 105 hp @ 5,800 rpm (75 kW) and 100 lb-ft of torque at 4,800 rpm (136 Nm). By using this cooling sequence, the intake air temperature is reduced and knocking resistance and volumetric efficiency are improved.

Unique to the 7A-FE were two-layer metal head gaskets, and a two-piece oil pan (one piece of aluminum alloy, the other of steel; the upper pan was secured to the cylinder block and transaxle housing). • Future

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). 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.

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. use 4a rods and a ge head thatd be interesting, http://members.optusnet.com.au/~saltheart/corollatrivia.html. Those corolla's also came with the 4AFE in them. Just wanted to know which of these accelerates the best??

* 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.

Hi guys!

7AFEs are gauge-redlined at 6200 rpm. I can get it a lot cheaper than I can get a 7afe. It was a compact DOHC engine for good economy and good driving characteristics. The engine control system for the new 4A-FE and 7A-FE engines had the same basic construction and operation as the engine control system in the previous 4A-FE engine. 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.

A plastic region-tightening method was used for cylinder head bolts to eliminate the need for periodical inspection of bolts. In previous engines, engine coolant from the radiator flowed to the cylinder block first, then to the cylinder head, but the new engine adopts a cooling system in which the intake side is cooled first. Toyota.

After the engine coolant cools the intake ports of the cylinder head, it then cools the cylinder block and cylinder head. You can post now and register later. The fluid inside the fluid chamber reduced the dynamic spring modulus in the high-frequency vibration range and thus increases quietness in the passenger compartment.

Come join the discussion about restorations, performance, modifications, classifieds, troubleshooting, maintenance, and more! * 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.

By reducing the dynamic spring constant in the high frequency range, the cylindrically shaped liquid filled compound mount reduced vibration and noise.

The cooling system reached the bottom of the intake port first to reduce intake air temperature, improving knock resistance and efficiency. i wonder what the redlines on both of these engines are ??

The torque curve was fairly flat, with a steep, linear horsepower curve.

  Your link has been automatically embedded. Whats the Difference between a 7a-fe and a 4a-fe motor? In 1993, the 4A-FE was given better intake efficiency through use of upright, small-diameter intake ports in the cylinder head, increased valve lift and intake valve diameter; a rotary solenoid type idle air control valve; and a large aluminum stiffener and vanadium-steel crankshaft to reduce noise and vibration.

Any one kindly tell me which engine has better fuel economy . Just look on the distributor and there should be a sticker that says 7AFE or 4AFE.. 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.

The cam profile in the 7a produces peak torque at 2800rpm and peak power at 5600rpm. ×

For the right-hand engine mount, newly designed: The newly-developed liquid filled compound mount had an insulator filled with a fluid.   Pasted as rich text. You can find them in 93-96 corolla's. • FAQ • Toyotas JavaScript is disabled. I guess its 7AFE but anybody who has tried these practically plz comment.

• History

In addition, a brace between the head and throttle body was added to reduce vibration. 4a with a 7a crank anyone??

7a-fe produces torque much lower than the 4afe . I am fitting a 4afe into a ae95 i thought the two engines are the same but there is a few differences like knock sensor and a extra port about the size of the ten cent coin below the inlet port for cylinder 1,and what looks like a 7A grey fuel injectors. Both engines shared a pentroof type combusion chamber, with cross-flow manifolds. More Toyota engines at toyoland • Camry • RAV4 • Corollas at Corolland, Home • Privacy/Terms
