The Toyota 13BT Specifications

by Karen Adams

The Toyota 13BT engine was a diesel-powered engine for Toyota Land Cruisers that provided a turbocharged option needed in off-road vehicles. The BT engine is Toyota's powerful version of the 3B 3.4-L, inline, four-cylinder eight valve OHV diesel engine except with direct fuel injection. Toyota's 13BT engine provides a great option for horsepower.

History of 13BT

Honda introduced the 13BT model in 1985 along with the 12HT for Land Cruisers in 1985. The 13BT engine is an add-on to the standard 13B engine for Land Cruisers. The T indicates the engine as turbocharged, which means it has a gas compressor necessary for forced induction in an internal combustion engine. The turbocharged engine increases the density of air as it enters the engine and creates more power.
