In a rotary, they're not really pistons, they're rotors. Definitely get some more reading in before you blow the engine up :D
One other big tip: don't rev it high until it's at operating temperature. And in the same vein, don't drive it immediately after starting, give it a bit of time to idle.
Aye! It actually says something along that line in the owners manual.. It has all of the paperwork and history of work done on the car. Looks like they actually replaced the apex seals once by the look of it but trying to figure out what year.
Save blowing the housing up or warping the cooling bits the scary part is from what I read the wankel will still run even blown up basically. 0_0
I've yet to actually take it for a spin yet. Certainly a car I'm going to want to have a tool chest stashed on. :)
