There you go mate,
Press the image button two along from the smiley face and paste your link in the box that pops up.
IMO the guys above are spot on. You can screw a bit over 200bhp out of an st200 in the real world, or you can build a 250bhp zetec turbo for peanuts, it'll be a hoot to drive, be worth more and cost you less (plus you might stand a chance of insuring the thing).
Of your dead set then fair play, they do sound awesome with the right exhaust and no cats.
Get a scrap engine first, offer it upto the shell and see how much of a ball ache it is, i suspect MAJOR. Then buy a zetec.
