As the portmanteau suggests, what you're looking at here is a 100E Pop with a Cosworth YB stuffed into it. Which is a huge amount of engine for such a tiny car...
And yes, you'd be right in thinking that this isn't the easiest conversion to carry out. Indeed, the Popworth has been a decade-long labour of love for its owner. You can see from this Turbosport build thread (which dates back to August 2004!) that the project has comprised no end of problem-solving, fabrication, customisation, swearing, and skinned knuckles. The end result is pretty stunning though, isn't it?
These photos were taken at the 2014 Retro Show, where it made its debut as a finished(ish) project. Click here for more photos.
