I purchased a Precision SC50 t3/t4 turbo along with a RevHard tubular manifold. I'm a little worried about the difference in the diameter of the bolt holes of the two products. The turbo flange's bolt holes are slightly larger than the threaded holes on the manifold itself where they meet. Will this be ok? Should I use some crush washers to prevent any backing out?


Thanks

The metal that the manifold is made out of and the metal that the turbo are made out of most likely expand/contract at slightly different rates. Oversize holes would beefit this slight. Definatly use some locking washers though.
