Most people are using something similar to that for a custom v-mount setup. If you're interested in a FMIC, you want something like this:

Could I do a custom v mount for under $400, because I heard they're pretty pricey. As far as fabrication goes I can do that.

If you can fabricate, then yes, you could fairly easily build a V-mount for $400. Metal is cheap, as are welding supplies.

As for that intercooler, those inlets/outlets would require significant alteration of the rad supports to use, if they fit at all. Generally if you are going to do something custom it's better just to cut off the end tanks (or buy a core only) and build end tanks which place inlets/outlets where you want them.
