Having driven one of the largest engines in ITA, I feel your pain. We were in the same boat. ----- We even ran ITS with the car once, but that's another story.
13B is called a 13B for a reason... 1.3L.

Correct me here Greg but common thought process:
Even though the 13B may have 1300ish cc's of actual volume it acts like a 2-stroke. So they class it effectively as 2.6L because it has twice as many power strokes per revolution as a conventional piston engine...1 power stroke per rotor every revolution whereas the CPE has 1 PS every other revolution.

By that reason, the 325's M20 normally called 2492cc motor is actually a 1247cc's because that's what it uses in one revolution of the crank, so it's STL legal then

Right!By that reason, the 325's M20 normally called 2492cc motor is actually a 1247cc's because that's what it uses in one revolution of the crank, so it's STL legal then
And if one wants to get pissy about it...go read the GCR Technical Glossary definition (which I don't agree with, and tried to get corrected...)
