Technical specifications

Features & highlights

The 4JB1 combines a rugged inline-4 block with a durable valve cover and a naturally aspirated intake for simple, reliable operation. A mechanical injection pump with high-pressure fuel lines delivers accurate fuel to each cylinder for efficient combustion, while the water-cooled system — front pulley drive and white cooling fan — keeps operating temperatures stable. Fewer components mean lower complexity, easier service, and reduced downtime.
