Those aren't intercoolers they're oil coolers. This is from some tokyo auto show where I believe it was to see how bizzare/outrageous you could make the car. It was all cosmetics, believe me the japanese know what ACTUALLY makes a car perform and what's for looks. So, really they are all ok cars considering what they were trying to do with them. The Silvia and the Skyline aren't too bad, same with the Fairlady and the GTO. Gotta hand it to the japanese though, wow no one over here would ever think of doing that to a car.
