FMIC.
..i did my kit by myself, i/c, polished piping, hoses & clamps from ebay, twin fans, homemad shroud.
Cost?
<$600
But in support of Auzveccy, getting a fmic kit to the stage where -everyone- can fit it by themselves, you would have to charge extra for all that headache.
edit: In addition, in Auz's kit, all the pipes will be cut to length ready to install, as well as having the ends rolled or flanged to help keep the hoses on. Saves a lot of hassle...
