The 3S GTE engine has many reported problems. One of these is cracking in the engine block. This issue occurs most often with the third generation blocks, but has also occurred with older versions. If you are thinking about buying a 3S-GTE engine, you should be aware of these issues.
Gen 2 BEAMS
A BEAMS motor isn’t a 3S GTE engine, but it is similar. Both engines have similar power figures, but one has larger turbos and a larger injector. Beams have a different valve arrangement, but the non-interference piston designed for the 3sgte will fit.
A Gen 2 BEAMS engine has the same compression ratio as a Gen 3 engine, but it has a higher power output. It also has the same torque figures. It also receives a minor revision to reduce emissions. The 3S-GTE 2.0L engine is very popular and is a popular turbo modification.
Another difference between a Gen 2 and Gen 3S GTE engine is the material used for the cylinder blocks. The 3S-GTE 2.0 inline-4 engine uses cast iron for the block. This material is desired for its strength and durability.
Gen 4 BEAMS
BEAMS (pronounced “Beames”) is a term used to refer to a modification that enables the engine to make more power than the original. In fact, it’s a shortened term for variable valve timing (VVT). Gen 4 BEAMS features enlarged inlet and outlet valves and camshafts that have a duration of 248 degrees and lift of 8.56mm and 8.3mm. The compression ratio was increased to 11.1 and power reached 200 HP at 7,000 rpm.
The 3S GTE 2.0-liter engine has been in production for more than 20 years and has undergone several updates and upgrades. It features a heavy cast-iron block that provides excellent strength. It also has aluminum cylinder heads that keep the weight low. It uses a DOHC 16-valve design.
Gen 5 BEAMS
Gen 5 BEAMS for 3S GTE engine is the successor to the Gen 3 BEAMS. It features identical wiring and identical power output. It was first released in the RAV4 and second generation Caldina Active Sports GT. It was dubbed “Grey Top” because of its grey intake plenum. Its torque figure is 140 kW or 180 PS at 6,600 rpm.
The Gen 5 BEAMS are designed to provide a stronger, lighter, and more durable engine. The block is forged from cast iron for strength and durability.
Gen 6 BEAMS
There are several advantages to Gen 6 Beams engines over Gen 3 ones. The first is that these engines are made for high revving, NA power. In comparison to Gen 3, they have a much higher compression ratio. Consequently, the resulting power is more linear. In addition, they are more predictable and are great for daily driving and other environments that require a wide range of power.
The Gen 4 BEAMS/Red Top (1997) engine was the fourth 3S-GE generation. It featured variable valve timing (VVT) technology. The valves were enlarged to 34.5mm in diameter and were paired with a camshaft with a duration of 248 degrees and a lift of 8.56mm. This allowed the 3S GTE engine to reach 256 HP and 239 lb-ft of torque.
Gen 7 BEAMS
Using Gen 7 BEAMS on a 3S GTE engine is a great way to increase power. The Gen 3 engine had increased torque figures and power output, but the Gen 3 engine underwent a minor revision in 1996 for emissions and reduced power output. It also lacked VVT-i.
The third-generation 3S GTE engine was produced from 1994 to 1999. The power output for the Japanese market increased to 180 PS, and the compression ratio was increased to 10.3. In the other markets, the power output decreased to 170 PS at 7,000 rpm. The torque remains the same at 19 kgm (191 Nm).
The Gen 7 BEAMS for 3S GTE engine has a new exhaust system. This system consists of a new exhaust system, a new exhaust manifold and an air-to-air top mount intercooler. The new design also features a new valve cover and exhaust housing.
