The Toyota 2T-G is a 1.6 liter (1,588 cc, 96.9 cu in) straight-four, four-stroke carburetor gasoline engine from Toyota T-family. The Toyota 2T-G engine was produced from 1970 through 1975.
This engine used DOHC (dual overhead camshafts) design with two valves per cylinder (8 valves in total), cast-iron cylinder block and an alloy cylinder head with hardened valve seats and a hemispherical combustion chamber design (HEMI). The 2T-G engine utilizes a timing chain.
Bore and stroke are 85.0 mm (3.35 in) and 70.0 mm (2.76 in), respectively.
The 2T-G engine has a twin sidedraft 40 mm (1.6 in) Mikuni-Solex PHH carburetors and produced 115.6 PS (85 kW; 114 HP) at 6,400 rpm of horsepower and 142 Nm (14.5 kg·m; 104.8 ft·lb) at 5,200 rpm of peak torque. Compression ratio rating is 9.8:1.
The 2T-GR is like the prementioned 2T-G, but with the lower compression ratio rating of 8.8:1. That “R” stands for Regular gasoline, and that is the reason for the lower compression. This engine produced 110 PS (82 kW; 112 HP) at 6,000 rpm of horsepower and 140 Nm (14.0 kg·m; 104 ft·lb) at 4,800 rpm of peak torque.
The breakdown of the engine code is as follows:
- 2 – 2nd generation engine
- T – Engine family
- G – Performance wide-angle DOHC
