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.
The 4T-GTE variant of this engine allowed Toyota to compete in the World Rally Championship in the early 1980s, making it the first Japanese manufacturer to do so.
Race engines based on the 2T-G include the 100E and 151E.
The first T engine displaced 1,407 cc and was produced from 1970 through 1979. Cylinder bore is 80 mm (3.15 in) and stroke is 70 mm (2.76 in).
Output is 86 hp (64 kW) at 6,000 rpm and 85 lb·ft (115 N·m) at 3,800 rpm. The more-powerful (95 PS) 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).
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) at 6,000 rpm and 11.3 kg·m (111 N·m; 82 lb·ft) at 3,800 rpm.
The T-U also appeared in 1977 with even stricter emission equipment for Japanese market non-commercial vehicles.
Applications:
The larger 1,588 cc 2T was produced from 1970 through 1984. Cylinder bore is 85 mm and stroke is 70 mm.
The 2T engines are usually coupled with either a T40 4 speed/T50 5 speed manual transmission, or an A40 3 speed automatic transmission.
Output for the early 2T-C bigport design is 102 hp which is also due to different SAE testing methods, while the later version is 75 hp (56 kW) at 5200 rpm and 86 lb·ft (116 Nm) at 3800 rpm, compression at 9.0:1. The twin-carb 2T-B produces 90-105 hp (67-78 kW) and 85–102 lb·ft (115-138 N·m). The 2T-J, for commercial vehicles with less restrictive emissions standards, produces 93 PS (68 kW) at 6000 rpm and 13.1 kg·m (128 N·m; 95 lb·ft) at 3800 rpm.
