the only way to mount an aftermarket wastegate is get an aftermarket single turbo manifold....really no place to put it on the stock manifold

i have pics... but cant find them on my hard drive. basically, pull the turbo assembly out, generously spray some wd40 or bolt loosener onto all the bolts, scratch a mark into the metal to show you how to realign the snails to the rotating assembly, pull all the bolts out to disassemble the turbos, (hope you dont find any cracks the size of the marianas trench), now that youre at the wastegate get some spray paint and spray with the WG closed (to show you how far is too far to port it), and then take a dremel to the WG hole. reassemble and wala. maybe consider rebuilding the rotating assemblies while youre in there.

if you want more specifics/pics let me know. -heath
