1/16 scale kits of modern cars?

[Fat Brian]

I recently saw a video of a mid engined v8 VW bug and now I want to build it. I love the early split rear window, shorter windshield, and teardrop headlights so I'm going to have to use the 1/16 Revell kit but i dont know where I'd get a modern v8 and transaxle in that scale. The actual car uses an Audi twin turbo engine and transaxle but I don't care about the brand as long as the setup fits in the bug body.
