I would say you could swap the exhaust housing for a .63 easy it all depends on the core inside the rear exhaust wheel but then again if the exhaust wheel is too big you could have it machined down
give martin a call on monday and see what he recons i dont think you will have a problem
there is one thing you have to do tho , where your oil return from the turbo thats goes back to the sump that will have to be lenthend in some way by about 10mm and it needs to be modded from the turbo end
something like a spacer that has to be welded
