If the RX-8 came with a 300hp V6 would you be happy or sad?

It only shows one performs better on track and one more forgiving on the street. I don't recall ever saying they are the same, do you even understand the word "similar", big deal with your 4 seat vs 2 seat, I could just easily rephrased it similar to a G35 which is the SIMILAR thing as the Z.
Okay, fine, they'll be 'similar'. Congrats on winning the unrealistic argument!

From http://www.autozine.org/html/Mazda/RX8.html: "Low center of gravity, low polar moment of inertia and perfect weight distribution are what all sports car engineers dream for, but not many cars can achieve them. For example, Nissan 350Z with its big V6 engine achieves only 53:47 and a much higher polar moment of inertia because a portion of its V6 hangs over the front axle. Benefited by the weight and size advantage of Wankel engine, Mazda RX-8 can easily beat its opposition even though it is a 4-seater. Chassis engineers will love this car."

By the way, a RX without a rotary is not a RX.

Some day I may swap in an LS2 or, hell, even an S2K engine.

No I wouldn't be too happy. They got a RX8 test mule to 255 hp with the Renesis, can't see why it can't be done. Or either turbo it, or 3 rotor it and call it day. Why 300 hp V6 ? If you are going to butcher the car, they already have RX7's with LS1's in them, so why not a lightweight V8 then ? But the Renesis can be improved on. Just needs some work on it.
.....anyways i like my RXocho the way it is...
