it doesnt attach to the downpipe or turbo, it attaches to the block around the downpipe and turbo. Theres the intercooler bracket and another one below the turbo, IIRC. I think I have the bottom one, intercooler bracket is obviously holding in my intercooler.
If you can take a picture of everything you have, i can see if I have a missing part, I cant remember how it all goes together.
