Dale, mate, sit down here with your Uncle Dwarf and lets have a friendly non-flaming chat over a nice cup of internet.
Firstly, you require some research. Google.com is excellent, as somewhere in the world, someone has done any given engine conversion. Honestly. If you want to put a quad-cam into a Honda Zot, some bloke in Uzbechistan has already done it and put it onto the internet. All the other usuals like Toyomods, twincam.org and there's another one that I can't remember right now (it's late) are useful resources, too. They all have search functions, and Toyomods especially mercilessly flame anyone who hasn't done their homework.
Unless you're excessively clever and know some really talented people, fast = expensive. And the dollars compound the faster you want to go. A 12 second car is cubic dollars. If you're pumping out big neddies, you WILL need upgraded drivetrain, and to prevent really bad things happening at the end of your ten second pass, brakes and suspension, too.
Here's a friendly tip, don't believe everything people tell you. Go out to your car with a tape measure, ruler, calipers, micrometer, piece of string, and see for yourself if things'll fit. I'll gaurantee, if it looks like it may not fit, it wont.
Sadly not many of us in here play with these new fangled FWD cars, but we would be interested to see what you come up with.
Good Luck!
