what is this car?

I would think even a stout turboed 4cyl. would make that thing fly. I don't think I'd want to crash it though.
I think the baddest motor you could get in a Lotus Seven was around 100-125hp, and even that was seriously quick. Can you imagine a 350hp Honda, Mitsubishi or Subie in one? Yikes! ( probably equivalent to a 1300hp hellcat). I think Caterham will sell you a 1500 lb version with 250 hp.
