just go out and grab a 13bt manifold from a turbo fc 86-91. match it to a 12a flange and grind the holes inwards 5mm each and port out the exhaust ports a little.
dont even think about using a file like me. it took about 4 hours , 1 ea hole to file them out 90%, my dad came home and found his dremel. it cut into the cast like a hot knife threw butter.
then throw a gasket inbetween the two and bolt it on the engine. this will give you plenty of room so the turbo doesn't kit the intake manifold or the idler arm.
here are some pics of my manifold that i wallowed out and the turbo. 91 j-spec

p.s. you might need longer exhaust studs. easy fix.
