I was kinda thinking someone would put that!.. Callaway (named after the founder) is like the american version of what turbo technics did here with the golf. Callaway is probably best know for the turbos they do for corvettes, but they also did a kit for the golf (or rabbit as its know in the usa) way back when. From what I can gather callaway only fitted 300 of their turbo kits to a few of the vw range. I think they also made a few to buy and DIY but not too many. Anyways, point is I've managed to bag myself one of these kits, but I'm missing the rocker cover (not necessary but helps it all come together), and the micro-fueler for the 5th injector, although I've since found I can get a newer version of this. It would be awesome tho to have a complete original kit as there VERY rare!!.. and when the day comes that I have to part company with my beloved golf, it would be a good selling point and some great history for the car!
