Skimmed a write-up on the RX8 in the May issue of Sports Car

International today. They gave the

weight of the engine sans all peripheral components (no word if that

included the water pump

housing or not) as 121 lbs (!) (vs. approx. 180 lbs for the previous

13-B found in the RX7).

    This sounds too good to be true, but if it is, there are now a bunch

of planes that previously

couldn't accomodate the 2-rotor 13-B but now can. Anyone on here heard

different?

Basically the engine is no different than the current engine. About 190

pounds bare.

Makes you wonder where some of these publications get their info. They did
give the complete (all external components attached) weight as around
270-something lbs. That should have been my 1st clue, since the external
components aren't likely to tip the scales at anywhere near the 150+ lbs
that their given bare weight would indicate.

Thats about right. Flywheel alone is 14.5 pounds. Starter 7 pounds 
alternator 7 to 8 pounds, AC compressor 10 pounds and so on.
Water pump probably 3 to 4 pounds.
