if you know anyone with a turbo manifold for an SR20DET pull youre exhaust manifold of and see if it will fit good, if not then you'll have to go the custom route. Good Luck!!
Yeah I know I am trying to see if anyone on here owns a shop or knows of a shop that will do it... the only shop I have found in AZ that will do it is going to charge me over 1K to do it
