i building a replacement for my fiesta, and i've just bought a 2.0 zetec from a focus.

the engine is being mid mounted into a mini.

i was wondering what my options were for tuning it, and i have just a few questions!

the car will be on aftermarket management, as i dont want to mess around with an old loom. got a few ideas, but any suggestions would be welcome

obviously there's the turbo option, but i don't realy want too harsh a power delivery, as i dont want the car swapping ends permantly! but do roller bearing turbos provided a solution for this?

i was also seriously considering the powerworks supercharger option, has anyone had any experience of these? the dollar is weak as hell at the moment, so its getting cheaper all the time!

where in the engine to i need to concentrate? is there a specific weak link, or a certain part that restricts performance?

basically i dont want to be bolting bits on/in if i'm wasting my money, and should be heading in another direction!

any other input would be greatly appreciated.
