well, there's really not much to it, buy yourself an intercooler that will fit in the space you have ( I got mine from a place called ssautochrome was 200 bucks to my door, and this was back when a us dollar cost a bit more... but you can easily find used volvo ic's for half that , and someone posted a link a while back to another company that had super cheap ic's.)
make it fit, run a couple hoses...I used marine wet exhaust hose for the piping where I needed rubber joints. silicone fittings are a waste of money unless you're after the bling.
so it's not a complex thing really, it's just making it fit.I did it to the fj45 I had and things were different in that engine bay, so I had tons of room to move the rad back.
hell if you want to go totally ghetto, you could just stick it ontop of the front bumper, run some hoses and do a test run that way.
