What is the difference between 4AFE and 4AGE?

The 4A-FE is different from the 4A-GE in terms of performance and power. Although both have the same displacement and are DOHC, they were optimized for different uses. The first obvious difference are the valves, the engine’s intake and exhaust valves were placed 22.3° apart (compared to 50° in the G-Engines).

Is 4AFE good engine?

Quite simply: one of the best engines ever created. The A-series was a remarkably light and powerful engine for it’s time, and the 4A-FE has to be about the ultimate expression of it’s type. No, it doesn’t have the performance of the 4A-GE, or the supercharged 4A-GZE.

Does 4AGE intake fit on 4AFE?

The 4age red top small port is the way to go on the head. This head will bolt onto a 4afe or 7afe.

Can I put 4AGE head on a 4Afe block?

But to answer your question, generally, yes it fits. All the 4A- blocks are the same, minor differences (7-ribbed, connecting rod differences, piston differences….).

How much power does the 4Afe make?

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). In California trim, it produced 100 hp (86 kW). It was a compact DOHC engine for good economy and good driving characteristics.

How many valves does a 4Afe engine have?

A narrow-valve DOHC 16-valve carburetor engine, the 4A-F, was produced from 1987 through 1990.

Can I put 4age head on a 4Afe block?

Which 4age engine is the best?

The Formula Atlantic-spec 4AGE engine is considered the Holy Grail of all 4AGEs, as it was developed by TRD to produce 250 hp and 130 ft-lb of torque, and revs up to 10,000 rpm.

What is the difference between a 20v blacktop and Silvertop?

The silvertop shares the same 48mm diameter thermostat as the 16V models while the Blacktop uses a significantly larger 56mm. – Blade / butterfly diameters: While both engines have round throttle blades, however the Blacktop throttle blades are larger at 45mm compared to the 43mm of the Silvertop.

What is the difference between 7afe and 4Afe?

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.

How many valves does the 4A-FE engine have?

What makes the 4A-GE special?

Formula One engines at the time derived power from high engine speeds, and this thinking went into developing the 4A-GE (higher engine speeds = better horsepower figures). In essence, the 4A-GE was a slice of Formula One technology, for the masses. 4 valves per cylinder was not the norm in 1983.

What is the difference between 4AGE blacktop and Silvertop?

While their valve size and position are identical the Silvertop features a chamber with a squish area in every gap between the valves. The Blacktop on the other hand features all but the smallest flat section behind the exhaust ports.

What is the difference between 5A engine and 4A engine?

The 4A-FE is a 1.6L but the 5A-FE is a 1.5L. Another difference is power output. The 4A-FE lays out 102HP and 101 FT-LBS torque, but the 5A-FE puts out 105HP and 97 FT-LBS of torque. Besides that, the motors are practically identical.

Is the 4afe and 4AGE the same thing?

i compared the 4AFE to the 4AGE cuase they are both injection..and the 4AFE and 4AFC share the same block I’m actully running the 4AFC with a 32/36 Weber for my carby.

Why use a 4afe in a car conversion?

Actually, the best reason for using a 4AFE in a conversion would be their availability. I was wandering around the wrecker’s today catching up with what he’s got in recently and there must have been six 4AFs in cars and no 4AGs at all.

Is the 4AGE 4AF head designed for performance?

The f series head was designed with economy in mind but there have been a few people test the head after they have done work to them and find that they out flow the 4age head. Would be interesting to see an actual 4af built with performance in mind.

How much horsepower does the 4A-FE have?

The 4A-FE 113 hp (84 kW) @ 5800 rpm Torque: 101 lb·ft (137 N·m) @ 4800 rpm…Redline: 6300 rpm The 4A-GE produced 112 hp (84 kW) @ 6,600 rpm and 131 N·m (97 lb·ft) of torque at 4,800 rpm
