could a better faster performance engine be installed into the smart fortwo?

anything can be installed, it all depends on money. a hayabusa is a definite possibility, and would probably be one of the cheaper swaps, along with something like a 13B rotary. but you would probablly need custom engine mounts, custom driveshafts, custom almost everything engine related. which would cost abit of money. but i have seen even things like an LS2 RWD conversion on a leland mini before, so anything is possible with enough time.

Yes a hayabusa engine can be installed into a smart fortwo- if you go on youtube.com you can find a video of the smart car with the engine installed in it.

BUT ONE PROBLEM!!!! IT COST 14K for a hayabusa kit :( I'm going to stick to the original engine and mod that.

My smart car 2002 starts engine and for 2 seconds turns off engine
