Ok so here's the deal, I decided to upgrade my turbo however the one I ended up getting requires an external wastegte. So as a solution I bought something like this :http://www.ebay.com/itm/T3-to-T3-Tu...ternal-wastegate-Relocation-JDM-/351196446788.
Now I have a problem, I wanted to upgrade to a 90+ manifold for better flow but as you know going from pre 90 to 90+ manifolds the turbo mounting style changed from through-bolt to studs. This posed a problem for me because the wastegate plate I bought wont fit completely on the manifold, the studs on the wastegate side of the adapter hit the small tube going to where the wastegate would be. This means I cant get the plate to sit on the manifold correctly and it also means that there's no way I would be able to get a nut on the stud coming through (unless they make very thin nuts that could squeeze in, or there was some way to machine the plate thinner where the bolt goes through to add more clearance). Here's the thing, the holes on the adapter plate are threaded so using a through-bolt style manifold would work much better (bolts would just thread into plate instead of turbo). Now I'm trying to find way to get my 90+ manifold to work with the adapter plate. I first though about removing the studs and putting bolts through the same holes essentially making it a through-bolt style, but then I realized that there would be no way to get the new bolts in (runners cover the holes from the back). so then i thought about taking the studs out removing the threads from the holes, insert a threaded rod from the front, somehow put a nut on the back of it as it comes through the back of the manifold and then weld it (essentially putting a bolt in backwards by welding a head on to it), but then I realized that the holes don't have much side clearance at the back of the 90+ so I don't think there'd be enough room to put a nut on the threaded rod. So I'm stuck, I could just use the original pre 90 manifold and avoid all of this but if there is a good solution I haven't thought of then maybe it could work. Thanks in advance.
