That wastegate has an adjustable end, the ones from the factory do not. They are a solid rod, no threads.
You need a total of 3 banjo bolts two are the same size for the coolant return line, one is smaller for the oil from the block. Then you have a threaded collar that is the same as for brake caliper, that is the oil in, on the turbo.
There is a tube and flange that you need for the oil return. It needs a piece of rubber hose to sleeve over it. It is just regular rubber hose.
If you get in touch with Greg V's store he will know every thing you need. I am sure there has to be someone selling this stuff in the classifieds also, so you could always just start pm ing those folks too.
I have a wastegate that is from a downward facing t25 compressor housing. You can have it for the cost of shipping if you want to try it. That might fit better than the one you have, if it doesn't there is a thread around on this board that shows how to modify it I think. PM me if you want it.
