I want to engineer a miniature car, like a 1/25 scale model car but with a working engine and transmission and exhaust system and everything else there is to a running car. I'm probably going to model it after a Honda Civic eg Hatch if I can figure out how to scale down a Vtec engine an if not probably just a 60's Mustang with a 4 banger under the hood. All I want to know is, is it possible or would I just be wasting my time?
