Rotarians,
I need to buy or fabricate a T04 exhaust manifold with a 46mm external
wastegate flange to fit my '93 3rd gen engine, TAil wastegate and T04-50
Turbonetics turbo. I'm considering one of the items below to at least form
the pattern to work from. I may have to "cut & paste" to move the turbo
location or angle, and these manifolds are made in 301 stainless, which may
not be up to the task.

My question is this - are the exhaust ports / bolt pattern for the 2nd and
3rd gen engines identical? Up to now I've been using a 2nd gen turbo and
manifold and it fits fine, so I think they must be.

Anyone have a suggestion for a good source for the manifold I need?
Happy new year, everyone.
