Vortech and Kenne Bell make direct bolt ons, but I only know of Vortech kits for the Mark. Kits would include all the little things and brackets that are custome to the Mark application. Kenne Bell is a better unit, but it requires you to find a shop that will make the extras, get a new hood for clearance, and find a top notch tuner to program it all.
A rear mounted turbo can also be installed (from STS Turbo), though like the Kenne Bell, you'd need to get the extras and tuning.
There are other units out there, but the three above are 50 state smog legal. (Don't know where you're from).
