Hyabusa engine can produce mega power, but it needs some strengthening work done to stop it breaking it's casings (even in bikes). I've seen a few bike engined cars, but most are pretty light. As soon as you start filling your car with passengers, luggage etc etc, you need a good bit of torque to drag you around.
By the time you buy a hyabusa engine (around £2k) and do all the mods needed, you'd have been better with something like a Zetec or the more modern duratec engine (loads lighter I'm told).
Last year at Crail there were 2 hyabusa engined Westfields (or similar) - 1 was standard, and the other was turbo charged, and surprisingly they were both about the same performance on the strip. I wasn't really impressed with their times - didn't seem that quick compared to some nice V8's out there
