Total Racing Products is pleased to offer a frame rail notch kit for those installing large frame turbos that cannot fit within the confines of unmodified frame rails when installing in the stock location. Some turbo kits on the market that utilize turbo sizes such as 67mm, 68mm, 76mm, and some other variations, require this modification to be performed in order to fit. Grab one of our notch kits today to make your installation an easier one.
