Starting with the B at 2.8 liters, the 1B, 2B, and 3B displace 3.0, 3.2, and 3.4 liters respectively.
With its ever abundant torque and power, the 3B is the most favoured engine of the lot. It’s rated power is 90hp@3500rpm.
The 3B also boasts the best oiling system of all the B series engines. Unlike other naturally aspirated diesels, it has oil injectors at the bottom of the cylinder skirts for better cylinder wall lubrication. Toyota replaced the 3B with the 13B-T. This is basically a technically updated and turbocharged version of the 3B and produces 120hp@3400rpm. It can also be found as the 13B in local markets. After much research, I have come to the conclusion that this is simply a 13B-T engine stripped of its turbo setup and outfitted with intake and exhaust manifolds off a regular B series engine. All commonly available B series engines can also be found with plunger or rotary fuel pumps. The plunger pump is slightly noisier, but it is also completely rebuildable and seems to have far more torque throughout the RPM range.
