Best for high performance

I was recently looking through some Lotus Elise forums and found a topic on engine swapping and someone mentioned swapping it with a motorcycle engine. With that said I was wondering if somebody were to place a motorcycle engine into an Elise, or any car for that matter, which motorcycle engine could be modified to have the most low end to all around torque and the most mid/high end to all around hp to best fit its purpose, and what the best way of going about all this would be. So in short I am wondering what the best way would be to get the best of both worlds and what motorcycle engine would be most up to the task(I was thinking about something along the lines of a 1liter, a zx-12r, or a gsxr-1300 engine but if something would be better than one of them then so be it). Oh and I do not actually have a lotus or anything to mod like that... it was just something that once pondered interested me... so with that said, if you feel this will be a waist of time to give me information that I might never put to use then by all means don't waist your time... I am just curious, Thanks.

Ohh and without the use of NOS if you will.

Get a 1300cc Busa engine, add a stroker kit anf make it a 1600cc or so and the throw in a turbo kit as well.

There is a Lotus Super 7 replica with this engine combo in it and it will kill almost any car out there. An absolutly amazing car.

How much Hp would it come up to after all that and what brand turbo kit would be the best?

http://www.zcars.org.uk/z100wr.htm (http://) Dude check out this link. Its a super 7 replica that uses 2 ZX1200 engines, 1 to power the front 2 wheels and 1 to power the rear. awesome.

the muzzy 1420 stroker for the zx12 makes more hp and torque than the 1500cc kit for the busa, so unless you are gonna get a turbo, i say go with the zx12 engine.

So does a Hayabusa react to a turbo system better than a zx-12r?

Also does anybody know what the HP and the torque increases to with the use of the 1427cc kit for the zx-12r and the 1661cc kit for the Hayabusa?
