The 91 is a good one. Mazda redesigned the exhaust manifold in 89 or 90 
and did away with the door that was causing the problems according to John 
at Mazdatrix. Here is a picture of the cracks on my 87 Turbo II
manifold. The picture is a bit out of focus as I was too close.

John mentioned porting the waste gate. I will take mine apart
in a day or so and see how feasible that looks.
