There are lots of Focus's running 200whp for several years now with no problems. Clutch and tranny mods are only needed if you're gonna flog the car a lot. Otherwise stock is fine.
Reading Corkey Bell's book, it says doubling the stock hp will only add around 20% extra stress to the engine. At least turbo'd because a quick spooling turbo will push most of it's power down low in the rpm band where the engine can handle it easier.
Easiest way to go FI is to do what LoCo did and buy the Focus JRSC kit and install it. The only problem is it won't get you anywhere near 200whp without serious mods. Virtually any turbo will get you 200whp with just a good exhaust.
It's all about tuning and how you drive it. If you run to the redline every shift and drive like you stole it, it won't last. If you just drive semi easy, it will last as long as most engines last...minus 20-25%.
But with used medium mileage zetec engines avaliable as low as $350, spares are easy to find.
