Compression ratio rating is 8.5:1.
- The 2T-C engine was produced from 1970 through 1979 for export market and used emission control system. This engine has a single down draught twin barrel carburetor and produced 88 PS (65 kW; 87 HP) at 6,000 rpm of maximum power and 124 Nm (12.5 kg·m; 91 ft·lb) at 3,800 rpm of peak torque. Compression ratio rating is 8.5:1.
- The 2T-U engine was produced from 1975 for JDM and used Toyota Total Clean System (TTC-C). This engine has a single down draught twin barrel carburetor and produced 90 PS (66 kW; 88 HP) at 6,000 rpm of maximum power and 127 Nm (13.0 kg·m; 94.4 ft·lb) at 3,800 rpm of peak torque. Compression ratio rating is 9.0:1.
- The 2T-J engine was produced for JDM`s commercial vehicles. This engine has a single down draught twin barrel carburetor and produced 93 PS (68 kW, 92 HP) at 6,000 rpm of power and 128 N⋅m (13.1 kg⋅m, 95.0 ft·lb) at 3,800 rpm of peak torque. Compression ratio rating is 8.5:1.

Agradezco por tan completa información y por los datos técnicos, estoy por adquirir un corolla del 75 y me será de mucha utilidad.
Sir, thank you for the information. I appreciate. I need info on the spark plug aluminum housing shafts. I have problems with oil entering these. New ones are difficult to find in SA
