edit: They dont rev so smooth with no apex seals.
FWIW, the RX7 in my avatar has over 300,000 miles on it, including pleanty of those miles on race tracks and autocross courses. Original engine had an oil control seal fail at 270,000 miles. They are sensitive to overheating being abused, but generally they are reliable if you take care of them.
To see info about the engine and performance mods on the RX8 engine check this out, they are aiming for 450hp in this one.
