View Full Version : Wastegate Adapter flange

10-05-2011, 06:31 PM
I'm looking for someone who can make me an adapter. I have a cast manifold that has a 2 bolt flange for the external 38mm wastegate. I have a 38mm wastegate, but it is a piece of garbage knockoff of the old old TiAL and it gets very inconsistent as it heats up. I also have a genuine 40mm 4 bolt HKS wastegate, that I would really like to use instead. I can't find an adapter anywhere that goes from the 2bolt 38mm to the 4 bolt 40mm.

Can anyone make one for me for around 50 bucks or less that would hold up well to the temps and pressures involved? I don't want to have to buy a third wastegate.
