I heard the rx8 13bs dont take well to forced induction because of high compression ratio and lightweight rotors, so my solution was the superdense (I believe thats what they are called?) rotors and a tune. Is this incorrect?

I was thinking ceramic to hold up better at high rpm? (another assuming info is correct) My plan was to basically prep the stock rx8 13b for FI down the road and this FI would be tuned for high rpm boost, since the rotories do well in high rpms anyway. haha I have accepted the plague of low torque at low rpms, it does not bother me too much. Anyway as for the 100k+ miles, I just dont want to get a used car and have the engine "fall apart" (I do understand its not literally falling apart rather just losing its compression ratio) after I get to 100k because the previous owner was a nincompoop and didnt know how to take care of a rotory car. So people are lucky and get good engines, but I hear of a lot who dont, so I dont want to prep the car just to need a new engine soon anyway. So I guess my question is will new seals (+ a tune) solve most compression ratio issues?
