The block that provided most of the parts for the engine I'll be installing 
is an '87 TurboII... if memory serves those have 8.5:1 compression rotors.

I wasn't convinced that going to 3mm apex seals was the right thing to do 
given my installation criteria, so I chose to go with Dave Atkins' 2-pc 
standard 2.5mm seals in lieu of the 3-pc stock Mazda units.

This is all getting really exciting for me, as I'm actually getting closer 
to putting the engine back together.  I've ordered new rotor housings from 
Dave along with his very neat cast wrap-over intake manifold and throttle 
body, and I'm expecting to see the parts later this week, early next 
week.  I'll send along some photos of the rest of the parts, including the 
ceramic coated rotors, and moly-coated side housings and gears.  I had the 
side and intermediate housings ported & polished before sending everything 
off for the coatings, and when they returned I found that the intakes had 
also been given the ceramic treatment... should be interesting.
