UUTLlNE OF CONSTRUCTtON
The BP SOHC engine for the 4WD model is the same as for the 2WD model, except that the flywheel is
shaped differently.
The 3P SOHC engine for the ECE specification (without catatyst) 4WD model is the same as the ECE US83
model, except that the fuel and emission control system and the engine electrical system are modified.
