MG Midget with a 13B Rotary

1978 MG Midget with a 13B Rotary

This 1978 MG Midget project started after it was submerged in a flood close to being restored. This would discourage many owners but not this builder. Instead he decide to go in a different direction and make a custom track monster. The factory 1493 cc engine (50-65 hp) was removed. In its place is a naturally aspirated 1.3 L Mazda 13B street ported two-rotor that produces around 170 hp. The uprights, brakes, and rear end are from a Miata. The suspension is a custom pushrod system developed by the owner using motorcycle shocks. Some serious fender flares were fabricated to cover the Hoosier slicks running off the much wider Miata track width. The owner even made his own steering wheel from wood and metal frame.

  1. I hate to burst your bubble , but my bugeye was the first spridget ever to be converted to a wankel . It’s still one of the fastest car in east Idaho area . You did a nice job on your car , but you didn’t have to change anything on the suspention or the hydraulic shocks , that is my biggest secret . Also , metal fender flairs ads more weight , those are against winning . Contact me if you want more secrets to the formula …..
