where can i get 83mm id aluminium elbows

[hough]

Basically im trying to find some aluminium elbows with an internal diameter of 83mm and a wall thickness of 1.6 to 2.0mm or does anyone know of a place that could bend a straight bit of tubing of 83mm id, as I want to make a new breather to turbo intake pipe for my car???

Have a look on this site here:

Not the exact size you require but they do joiners that allow size increases as well as reductions and flexible silicone joints that might get you very near the size you want. I think they can also make or have made some specials for you.

Good luck.
