The wastegate is plumbed back into the DP, the pipe is 2 inches in diameter and has one bolt hole on each side....any suggestions where to find such a thing?

 

What brand/size wastegate do you have? You can get gaskets for Tial, HKS, Turbosmart, Greddy, ect. ect. at Horsepowerfreaks.com, or through any dealers.

it's not actually for the wastegate, it's for the pipe that attaches to the DP. I believe it was custom, but it's an HKS wastegate. I'll check the site though, thanks.

 

blue water rubber and gasket
Houma,La. Get the material and cut your own.

 

Well even if it is a custom flange, I would think that it would have been made to the same size as the HKS flange. If so, it should work. I'm sure you can call HKS and figure out what size their flange gasket is.

Your HKS wastegate should of come with the gasket you need. If you can't find it call HKS USA and they can refer you to an authorized dealer to get a replacement.
