Toyota 3S-GTE 2.0T Engine Specs, Problems, Reliability

Toyota 3S-GTE 2.0T Engine Specs, Problems, Reliability. The 3S-GTE is a 2.0-liter inline-four turbocharged gasoline engine, produced by Toyota from 1986 to 2007. The engine is based on a naturally aspirated variation of Toyota’s 3S household – 3S-GE. This 2.0 L turbo engine was provided for the Toyota Celica (ST165, ST185, ST205), MR2, and Caldina GT-T/GT-Four.

Toyota 3S GTE 2.0T Engine Specs

Like the 3S-GE, the turbocharged version has a cast iron cylinder block, a forged crankshaft and connecting rods, and lightweight aluminum pistons. The 3SGTE differs from 3SGE by the reduced compression ratio for the turbocharging and the addition of piston oil jets (squirters) inside the cylinder block. On top of the block, there is an aluminum cylinder head developed by Yamaha. It is a 16-valve DOHC aluminum alloy head with the pent-roof combustion chambers where spark plugs are situated in the. The engine likewise uses a timing belt and strong buckets in the valvetrain (valve clearance is changed by adding shims over/under pails). Consumption valve diameter is 33.5 mm (1.32 in) exhaust valve size – 29.0 mm (1.14 in).

3S-GTE Gen 1

The first generation (1986 – 1989) has Toyota CT26 turbocharger with single entry turbine real estate and a single wastegate port design. It was equipped with 138 mm long linking rods, 430 cc fuel injectors, a 55 mm (2.2 in) throttle body, Toyota’s T-VIS (a variable consumption manifold), and a water-to-air intercooler. Consumption and exhaust valve lift are both 7.15 mm (0.281 in). With 8.5:1 compression ratio and 8-9 psi (0.55-0.62 bar) of increase, the engine produces 185-190 hp at 6,000 rpm and 184-190 lb-ft (250-258 Nm) of torque at 4,000 rpm. This generation can be discovered in the Celica GT-Four ST165.

3S-GTE Gen 2

The second gen 3S turbo engine was produced from 1989 to 1993. It was fitted with Toyota CT26A turbo, which has a twin entry turbine housing with double wastegate ports. The Gen 2 engine has increased compression ratio to 8.8:1 and camshafts with following specs: 236/236 degrees period; intake and exhaust valve lift is 8.2 mm (0.32 in). Consumption air is cooled by an air-to-air intercooler (top-mounted in the Celica GT-Four ST185 and side-mounted in the MR2). The 3SGTE Gen 2 remained injectors and throttle body from Gen 1, however with new parts and the increased boost to 10-11 psi (0.69-0.76 bar), it produces 200-232 hp at 6,000 rpm and 200-224 lb-ft (271-304 Nm) of torque at 3,200 rpm.

3S-GTE Gen 3

The third-gen three GTE (1993 – 1999) got a great deal of changes. It got a Toyota CT20b turbocharger, which has an enhanced turbine real estate and larger compressor wheel comparing to CT26A turbo. The consumption system was geared up with a water-to-air top-mounted intercooler and the 4-runner consumption manifold without T-VIS. There are new camshafts (duration – 240/236 degrees, valve lift 8.7/ 8.2 mm), 540 cc injectors, and 60 mm (2.4 in) throttle body. The max boost pressure likewise was increased to 13 psi (0.90 bar). The engine output is 245-255 hp at 6,000 rpm and 224 lb-ft (304 Nm) of torque at 4,000 rpm. Gen 3 engines were set up in the Celica GT-Four ST205 and MR2.

3S-GTE Gen 4

The 4th generation was produced from 1999 to 2007. This engine was utilized in the Toyota Caldina GT-T (ST215) and GT-Four (ST216). The 3S-GTE Gen 4 got a CT15B turbocharger, that made as one piece with a cylinder head exhaust manifold. Limit boost kept the same. Charged air goes through an air-to-air intercooler. The engine got brand-new webcams (period – 248/246 degrees, valve lift – 8.75/ 8.2 mm) and digitally controlled ignition system with the coil-on-plug function. The compression ratio is 9:1. In this configuration, 3S-GTE produces 260 hp at 6,200 rpm and 239 lb-ft (324 Nm) at 4,400 rpm.

In 2002, the engine was modified again. This variation was installed under the hood of the Toyota GT-Four (ST216) only and has minor differences compared to the previous setup, touching the fuel system, ignition, and some parts plan. The 2002+ 3S-GTE engines have 8.4 mm (0.33 in) intake valves. The last engine output has not altered.

Toyota 3S-GTE 2.0T Engine Problems and Reliability

When Toyota developed the 3S-GTE, it was an incredibly reliable engine. Today, a lot of have 20+ years of unknown maintenance and inappropriate mods. Hard sufficient to find a good stock three turbo engine with low mileage and it is the main problem of this engine. But if you got one, your engine will last as long as you keep it preserve following the maintenance schedule. Like all turbocharged engines, the three GTE likes a more often changed, great engine oil. Stock 3S-GTE engine life has to do with 180,000 miles (300,000 km).
