Having been nearly bankrupt by a local Nazi court, I have been forced to take a different route to meet my intercooling needs. Granted, I have a 91 so I have the grille and space (or most of the space) needed to stuff a 2nd gen cooler in there. I have the hoses and piping from a 94, just waiting on an intake and then the $150 or so to get a used one. Then a day or two for cutting, welding, fabrication.
From what I've read, people who have gone to a Banks IC have been pleased with them. Personally, with all the alternatives available, I think Banks is a little (ok, a lot) pricey, but to each his own. There are people happy with their bang-for-buck from Dr Performance.
