Jonathan Lamson's 1960 MGA Twin Cam w/ Mazda 12A Rotary Engine

as published in British V8 Newsletter, Volume XV Issue 2, September 2007

Owner: Jonathan Lamson
City: Rosemont, NJ
Model: 1960 MGA Twin Cam
Engine: Mazda 12A Wankel Rotary Engine
Conversion performed by: Previous Owners (unknown)

Engine: Mazda 12A (late 70's) with street porting, Racing Beat Manifold with four barrel carb, Racing Beat headers, stock electricals.
Transmission: stock Mazda 4-speed (late 70's). Custom driveshaft from "Driveline Service of Alexandria".
Brakes: Dunlop/Ferrari brakes.
Wheels/Tires: stock MGA Twin Cam wheels, except with 7" chevy rims welded on to accommodate wider tires.
Electrical Mods: all new wiring.
Body: louvered bonnet with leather hold-down straps. All badges removed. Trunk lid secured with hood pins (see photo). Original plywood floorboards have been replaced with stainless steel. (This definitely tightened up the chassis!) A driver's side roll-hoop was installed. Headlight stone guards were fitted.
Interior: completely reupholstered in red leather, with black carpeting and aluminum scuff plates installed on rocker panels, lower door panel and floor frame. Leather wrapped steering wheel.
Electrical: wiring completely replaced and converted into a 12V negative ground system.
Completed: 1986
Comments: Although it's not the quickest off the line, once she's moving and in her power curve she screams!
Future plans: I will be adding the racing style front apron, with cut-outs for air intake and for driving and/or fog lamps. Am considering replacing the dashboard with engine-turned stainless steel, and adding a few gauges (amp-meter, pyrometer, etc), plus push-button start.
