Honda B20B
This power unit is very reliable, rarely breaks down and only at high mileage.
The Honda S-MX is a Japanese box-style compact van from Honda Motor Co., Ltd. Manufactured in Japan from 1996 to 2002 exclusively for the domestic market. The model was produced in the back of a 4-seater minivan and was presented as a youth one. A 5-seater modification was also produced. In 2000, the exterior of the car underwent a restyling. The S-MX was produced in three trim levels in all- and front-wheel drive configurations.
The Honda S-MX was offered with 1 engine between 1996 and 2002 (1 petrol). Displacement ranges from 2.0 to 2.0 liters, power output from 125 to 150 hp. All of them use a timing belt.
