Also is the bolt pattern of the 87-91 13B turbo the
same as the 93-95 13BREW and the 13B Cosmo turbo?

Don't know yet Kelly. I don't think there was a 13B Cosmo turbo.

Paul I just stripped twin sequential turbos off my 13B Cosmo engine.

What do I know? :-)>.  I had a 1976 state side version of the
13B Cosmo and it was not turbo. Is Bulents also a twin turbo version?

Make a sketch or drawing of the intake manifold bolt pattern relative to the 
port locations and up load it. I'll check when I get the manifold from Tom.
