Well perhaps it isn't so complicated. Grandpa did have some good ideas, but the project would require a lot of highly specialised components and work to be done. Compared to just chucking a turbo on an EA six or V8, the costs would go through the roof.
A proper roll cage might even be necessary. A lot of testing for aerodynamics... you might be able to buy a Porsche cheaper after all.
