The Toyota T series is a family of inline-4 automobile engines manufactured by Toyota beginning in 1970 and ending in 1985. It started as a pushrod overhead valve (OHV) design and later performance oriented twin cam (DOHC) variants were added to the lineup. Toyota had built its solid reputation on the reliability of these engines.
Race engines based on the 2T-G include the 100E and 151E.
- All T engines utilize a timing chain and have a cast iron block with an alloy cylinder head with hardened valve seats and a hemispherical combustion chamber design (HEMI).
- All T engines are carburated except those with electronic fuel injection, "E" designation.
- All T engines use a 2 valve OHV design except those with a DOHC performance head, "G" designation.
- The 12T/13T has a sub-cylinder directly behind the spark plug that leads into a smaller chamber for emission purposes.

The first T engine displaced 1.4 L (1,407 cc) and was produced from 1970 through 1979. Cylinder bore and stroke is 80 mm × 70 mm (3.15 in × 2.76 in).
Output is 86 hp (64 kW; 87 PS) at 6,000 rpm and 115 N⋅m (85 lb⋅ft) at 3,800 rpm. The more-powerful 95 PS (70 kW; 94 hp) twin-carburetor T-B was produced for the first six years, as well as the single carb T-D which had a somewhat higher compression ratio for 90 PS (66 kW; 89 hp).
From 1977 there was also a T-J, a version with some simple emissions equipment intended for Japanese market commercial vehicles. With an 8.5:1 compression ratio, this produces 80 PS (59 kW; 79 hp) at 6,000 rpm and 11.3 kg⋅m (111 N⋅m; 82 lbf⋅ft) at 3,800 rpm.
The T-U also appeared in 1977 with even stricter emission equipment for Japanese market non-commercial vehicles.

The larger 1.6 L (1,588 cc) 2T was produced from 1970 through 1984. Cylinder bore and stroke is 85 mm × 70 mm (3.35 in × 2.76 in).
Output for the early 2T-C bigport design is 102 hp (76 kW; 103 PS) which is also due to different SAE testing methods, while the later version is 75 hp (56 kW; 76 PS) at 5200 rpm and 116 N⋅m (86 lb⋅ft) at 3800 rpm, compression at 9.0:1. The twin-carb 2T-B produces 90–105 hp (67–78 kW; 91–106 PS) and 115–138 N⋅m (85–102 lb⋅ft). The 2T-J, for commercial vehicles with less restrictive emissions standards, produces 93 PS (68 kW; 92 hp) at 6000 rpm and 13.1 kg⋅m (128 N⋅m; 95 lbf⋅ft) at 3800 rpm.

This engine was also commonly used in Australian Formula Two race cars during the 1970s and 1980s, where they typically made between 180 and 200 hp (149 kW; 203 PS). The 1979 championship was won by a Toyota 2T powered Cheetah mk6. In 1984 Peter Glover borrowed a Cheetah mk7 powered by Toyota 2T for one round. The car won the round and helped secure the championship.
The 1.6 L (1,588 cc) 12T and 12T-U (lean burn) was produced from 1970 through 1983. It produces 88 hp (66 kW; 89 PS) at 5,600 rpm and 130 N⋅m (96 lb⋅ft) at 3,400 rpm. There was also a 12T-J version for commercial vehicles, which didn't have to meet as stringent emissions standards in Japan. In response to Honda's CVCC emissions, Toyota introduced "TTC-L", using a lean burn implementation.

The 2T-G, produced from 1970 through 1983, is a chain driven 8v DOHC version. Output is 110–125 hp (82–93 kW; 112–127 PS) and 142–147 N⋅m (105–108 lb⋅ft). Variants include the air-injected 2T-GR, Japan-spec 2T-GU, and fuel injected 2T-GEU. Twin sidedraft 40 mm (1.6 in) Mikuni-Solex PHH carburetors were used in non EFI versions. All 2T-G cylinder heads were cast by Yamaha, however, some are not marked as such.
The 2T-G was replaced by the 4A-GE in most applications.

Like the 2.0 L 18R-G, the 2T-G was considered the flagship engine of Toyota's 1600 class until it was superseded by the 4A-GE in the 1980s. The 2T-G is still a popular engine for conversions to classic Celicas and Corollas and are often suitable for classic and formula racing series.
When bored out to a maximum of 89 mm (3.5 in) and combined with a 3T crankshaft, the 2T and 2T-G will have a displacement of almost 2.0 L. The 2T and 3T series use the same connecting rod dimensions, with the different pin heights on the pistons. Aftermarket pistons are available from very low (<7.0:1) through to very high (>13.0:1) compression ratios. Racing 2T-G engines ("NOVA") featured 87 mm × 84 mm (3.43 in × 3.31 in) bore and stroke for a 2.0 L (1,997 cc) displacement. Output is around 170 PS (125 kW; 168 hp) at 6,000 rpm with a 12.0:1 compression ratio. This engine was used in Formula 3 cars in both Europe and Japan (where it dominated), as well as in Formula Pacific (FP).
The 3T displaces 1.8 L (1,770 cc) and was produced from 1973 through 1985. Cylinder bore and stroke is 85 mm × 78 mm (3.35 in × 3.07 in). The 3T-U was originally compliant with Japan's 1976 emissions standards (TTC-C), from October 1977 it used Toyota's lean burn system called TGP ("Turbulence Generating Pot") in order to pass the 1978 emissions standards.
The 3T OHV engines are mated to either of a T40 4-speed, T50 5-speed manual transmission, or an A40 3-speed, or A40D 4-speed automatic transmission.
Output ranges from 70–105 hp (52–78 kW; 71–106 PS) and 126–162 N⋅m (93–119 lb⋅ft) between the California 3T-C and Japan-spec fuel injected 3T-EU.

The 3T-GTE, first released in September 1982, is the most performance oriented version of the 1.8 L (1,770 cc) 3T engine. It features a hemi chambered 8v twin-cam head with twin-spark (two spark plugs per cylinder) design and swirl inlet ports for better efficiency. The EFI system saw the introduction of knock control. It is turbocharged by a Toyota CT20 Turbo (the same unit as used in the 2L-T diesel) to generate 160��hp (119 kW; 162 PS) at 6,000 rpm and 206 N⋅m (152 lb⋅ft) at 4,800 rpm. This was the first turbocharged twin-cam engine built in Japan. Units built after May 1983 received a water cooled turbocharger. The engine was considerably over-engineered for durability, for instance featuring doubled cam roller chains, as it was also to form the basis for the 4T-GT competition engines. It either came mated to a W55 5speed manual with a larger 225 mm (8.9 in) clutch and lighter 8 kg (18 lb) flywheel or an A43D 4-speed automatic transmission.
3T-GTE powered vehicles are badged as GT-T or GT-TR.
This is the version of the T family which powered Toyota's Group B and World Rally Championship cars. The homologation engine, introduced in November 1982, features a 0.5 mm (0.020 in) increase in bore over the 3T, giving 1.8 L (1,791 cc). With a multiplication factor of 1.4 for turbocharged engines, this equalled 2.5 L (2,507 cc) in the eyes of the FIA, placing the Celica in the 2.5–3.0 L (2,501–3,000 cc) class. The smaller 3T engine would have fit snugly under the 2.5-liter limit, but being in the larger class allowed Toyota to stretch the 4T-GT engine to 2.1 L (2,090 cc), 89 mm × 84 mm (3.50 in × 3.31 in) for a converted displacement of 2.9 L (2,926 cc) which better suited the comparatively heavy Celica.
In race trim it was a high-performance engine of 2.1 L (2,090 cc) with either a Toyota or a KKK/K27 turbocharger, electronic fuel injection, and a twin-spark ignition system, producing 360 to 600 PS (265 to 441 kW; 355 to 592 hp) depending on race trim. The 1984 Group B rally version produced 326 PS (240 kW; 322 hp) at 8,000 rpm. The road going homologation version (4T-GTEU, 200 built) produces 180 PS (132 kW; 178 hp). The total build number, including modified versions, was 228.

The '100E' engine used twin spark plugs with 2 valves per cylinder but was used mainly by a Toyota works team.
The production 1.8 L (1,791 cc) 4T-GTE was stretched to 2.1 L (2,090 cc) for race use.
