Sounds more reasonable. It allows the bigger bimmer motors up to the
'95 M3. But the honker 3.2's aren't allowed. I think that's pretty good
though. I would guess most of the target audience is likely to be
running the 2.8's and 3.0's anyway I think. Also allows for the bigger
4-bangers from Porsche. The VW crowd will like that too. There are
stroker kits for the VR6 to bring them up to 3.0L I think (or is it
3.1L? I dunno).

1.3L, yup. The A, B and other designations (G) are more for generation
or version identification.

I guess you could build a 3-rotor motor to 1.5L from early 10A pieces.
But the 3-rotor motors from japan are all 2.0L, with the wicked scary
4-rotor motor coming in at 2.6L. I doubt a 3-rotor 1.5L built from 10A
parts would be able to compete against a well built 13b though.
With motors being unlimited, I'd be hard pressed to pick anything other
than a bridgeported, supercharged 13b for my mega-buck fun car. Hmm,
let's see, front engine, four seats, has to be in the same family...
Gee, that motor could go into just about anything. I can just hear it
now! <BWWAAAA HAAAA HAAAA> What exhaust note? That was the driver
screaming! :-)
