    Does not fit as described for a Fast 102

    The front drivers side bung has a recessed bolt head. It makes the bolt to long to be able to tighten down. Had to use a washer and it looks bad. Pictures are different slightly that what showed up. It says it was designed to fit a Fast 102 intake but the passenger front attachment that all the hoses go to points the 2 lines that goes to the rear directly into the intake housing. I am not sure I can even make this work. I bought this through BTR racing who dropped shipped it from Nitrous outlet. Not A happy customer.

    Limited steam line kits to fit a fast lsxrt intake. Gave this a try and ended up working out however was very frustrating to get it all together. had to take the tree apart and reinstall the fittings after placing the manifold. a very tight fit and had to file a small area of the intake bracing to get 90 degree fitting reinstalled. Probable much eisier with the intake off. Overall everything fit as it should

    Very nice parts

    This is a very nice part,but it does not fit 100 percent as said. I have a fast lsxrt intake and the passenger side where the main body is was to close to the intake. The line is also about a inch to short on the passenger side. I think I got it figured out by adding a taller nipple to the body and adding a 90° on the back port. I thought is if Im going to spend this much on some lines that quote they fit I should not have to buy more stainless parts. Over all this is a very nice part though.
