Yeah they do, an s/c kit on a 172 from k-tec is more than the 197 /200 kit will be. A turbo kit is like 7k fitted lol! It will be fast, around a stage 1 meg (265) to be fair, maybe a bit quicker as they are lighter.
It will be running sweet this week and should be getting it back (hopefully) once the project is finshed. Any teething problems will be rectified but it will be fine. There fiesta kits are mint, some people i no have had no trouble with them.
Ben from jamsport told me on his fiesta it was better on mpg as well! So i'll report on that once the 1st few weeks of foot to the floor have settled in lol!
