There's a nice Morris Minor near us that has a Fiat 2.0 Twin cam engine and modded running gear. Only give away is the size of tyres and exhaust. That would be quite a project to take on.
Most Japanese car's have a large following of modifiers especially with all the different sports like drifting, drag, time attack, GT racing etc to follow.
Personally I would of liked to have continued with my 944 turbo, enlarging the capacity to 2.8 or even 3.2 ltr but you're looking at a £20000+ build just for the engine then trying to get the car to transfer that torque to the road was just too much for my meagre funds. It's been done though and there's 8 car's I know of with a 3.2 conversion. A 968 turbo S recreation would be awesome as Porsche only made 4.
