Toyota 3S-FE/FSE/GE/GTE 2.0 engine

Toyota 3S engine characteristics

The Toyota 3S engine was manufactured at Kamigo and Toyota Motor Manufacturing Kentucky from 1984 to 2007. It has a cast iron cylinder block and can use either a carburetor or injector power system. It is an inline four-cylinder unit with four valves per cylinder and has a piston stroke and cylinder bore of 86 mm. Different compression ratios are available for different models, ranging from 8.5 to 11.5.

The engine displacement is 1998 cubic centimeters. Engine power ranges from 111 to 260 horsepower and torque from 162 to 324 Nm, depending on the specific modification.

For engine operation, it is recommended to use fuel with an octane number of 95 to 98. Fuel consumption for the Celica GT Turbo is 13.0 l/100 km in the city, 8.0 l/100 km on the highway and 9.5 l/100 km in the mixed cycle.

Recommended engine oils include 5W-30, 5W-40, 5W-50, 10W-30, 10W-40, 10W-50, 10W-60, 15W-40, 15W-50 and 20W-20. The capacity of the lubrication system depends on the specific engine model and varies from 3.9 to 5.1 liters. It is recommended to change the oil every 10000 km, although it is better to reduce this interval to 5000 km.

The operating temperature of the engine is 95 degrees Celsius. According to the factory, the engine resource is not specified, but in practice its life cycle can exceed 300 thousand kilometers.

Variants of the Toyota 3S engine

3S-FC

3S-FC – carbureted version of the engine, was installed on more affordable models of Camry V20 and Holden Apollo cars. The compression ratio was 9.8 and the power output was 111 hp. This engine was produced from 1986 to 1991 and is rare.

3S-FE

The 3S-FE was the injector version and the main engine of the 3S series. It used two ignition coils, and while it was possible to use 92 octane gasoline, 95 was preferred. The compression ratio was 9.8 and power ranged from 115 to 130 hp depending on model and firmware. The 3S-FE engine was installed from 1986 through 2000 in a wide range of vehicles.

3S-FSE (D4)

The 3S-FSE (D4) is Toyota’s first direct injection engine. It features a VVTi variable valve timing system on the intake shaft, an intake manifold with adjustable channel cross-section, pistons with a notch to direct the mixture, modified injectors and plugs, an electronic throttle and an EGR valve for exhaust gas re-combustion. The compression ratio is 9.8 and output is 150 hp. Although technologically advanced, this engine has a reputation for being unreliable and problematic, with frequent failures of the fuel injector, EGR, problems with the variable intake manifold requiring periodic cleaning, as well as the catalytic converter and injectors.

3S-GE

The 3S-GE is an improved version of the 3S-FE engine. Its cylinder head was modified with input from Yamaha, and the pistons were counterbored to prevent the pistons from colliding with the valves in the event of a timing belt failure. This version also lacked an EGR valve.
There were 5 variants of the engine produced during production:

3S-GE Gen 1

The first generation 3S-GE, produced until 1989. Compression ratio was 9.2 and camshaft phasing was 240 degrees. Power output was up to 160 hp.

3S-GE Gen 2

The second generation 3S-GE was produced until 1993. The T-VIS adjustable intake manifold was replaced by ACIS and the compression ratio was increased to 10. Power rose to 165 hp.

3S-GE Gen 3

The third generation 3S-GE was in production until 1999. The compression ratio was 10.3 and power rose to 180 hp for the Japanese version and 170 hp for the export version.

3S-GE Gen 4 BEAMS/Red Top

The fourth generation 3S-GE, produced in 1997, had a VVTi variable valve timing system. Power output reached 200 hp.

3S-GE Gen 5

The latest, fifth generation 3S-GE, features a Dual VVT-i variable valve timing system on both shafts. Power output is rated at 200 hp.

3S-GTE

In parallel with the GE series, their turbocharged modification – GTE – was also produced.

3S-GTE Gen 1

The first generation 3S-GTE was produced until 1989. It is a stripped down version of the 3S-GE Gen1 with a CT26 turbine and water-cooled intercooler. Power output was 185 hp.

3S-GTE Gen 2

The second generation 3S-GTE was produced until 1993. Power rose to 220 hp.

3S-GTE Gen 3

The third generation 3S-GTE was in production until 1999. Power reached 245 hp.

3S-GTE Gen 4

The fourth generation 3S-GTE was in production until 2002. Power output was 260 hp.

3S-GTE Gen 5

The last generation 3S-GTE, produced until 2007, remained the same in terms of power and boost pressure.

Faults and their causes

1. The failure of the fuel injector on the 3S-FSE, accompanied by gasoline in the crankcase and severe wear of the pinion. Signs: oil level rises (oil smells like gasoline), the car jerks, runs unevenly, stalls, revs float. Solution: change the fuel injector.
2. EGR valve, this is a perennial problem on all engines with EGR. Over time, when using low-quality gasoline, the EGR valve is encrusted, begins to wedge and eventually ceases to operate completely, along with floating revs, the engine is dull, does not go, etc. The problem is solved by systematic cleaning of the valve, or its silencing.
3. RPM drops, stalls, does not drive. All problems with idling, in most cases, are solved by cleaning the throttle block, if it did not help, then clean the intake manifold. In addition, the cause can be a gas pump and dirty air filter.
4. High fuel consumption on the 3S, sometimes even absurd. Adjust ignition, clean injectors, ECU, idle valve.
5. Vibrations. Eliminated by replacing the engine cushion, or cylinder is not working.
6. Burning 3S. The problem lies in the radiator cap, replace.

In general, the Toyota 3S engine is good, with adequate maintenance drives long and quite sharp. Resource, in normal conditions, easily exceeds 300 thousand kilometers. If you do not complicate your life and do not take 3S-FSE, there will be no problems with the engine.

On the basis of 3S were produced modifications with different working volumes, younger brother 4S – 1.8 liters, bored version 5S – 2.2 liters.

In 2000, there was a new motor 1AZ-FE, which replaced the veteran 3S.

Tuning the engine Toyota 3S-FE/3S-FSE/3S-GE/3S-GTE

Chip tuning. Atmo

Toyota engines 3S-GE and 3S-GTE are perfectly adapted to refinements, the confirmation of this are Le-Man motors 3S-GT with an output of 700 hp, more simple 3S-FE/3S-FSE there is no sense to refine, to increase their output will have to replace everything that can be, the increased load of the stock FE will not withstand, and given the age, tuning will end with overhaul. It is easier and cheaper to replace 3S-FE with 3S-GE/GTE.

What about GE, they are not badly squeezed without you and me, that to move on it is necessary to put a light forged cog, lightweight crankshaft, everything should be balanced. We grind the cylinder head, intake exhaust channels, bring the combustion chambers, valves with titanium plates, camshafts with phase 272, lift 10.2 mm, straight exhaust on 63mm pipe, with spider 4-2-1, Apexi S-AFC II. This will add up to 25% more hp and your 3S will rev past 8000 rpm. For further movements, you need to put shafts with phase over 300 and maximum lift, cut gears, disable VVTi, 4-throttle intake (from TRD for example) and spin for 9000 rpm until it falls apart.

Turbo on 3S-GE/3S-GTE

For trouble-free operation of GTE version, just make a chip, get their +30-40 hp and no questions. To get serious power you need to remove the standard turbo, look for a turbo kit with intercooler for the required power (the most balanced option is Garrett GT28) and depending on this to choose more powerful injectors (from 630ss), bottom forged (preferably), shafts phase 268, gasoline pump from Supra, exhaust straight pipe on 76 pipe, tuning AEM EMS. Config will show about 350 hp. Further increase in power is possible with the use of a kit based on Garrett GT30 or GT35, with reinforced bottom end, the ride will be fast, loud, but not long.
