Since the RX8 is so slow, and since it only has a 1.3 litre..80 cubic engine, I will suggest a upgrade to 2.0 litres 120 cubic inches, and with current output of 250 with 1.3 litre, then its right to have 375 with 120 cubic inches of raw rotary N/A power. With the added weight of the third rotor, torque will go up greatly..Ahh 3 rotor you can dream...lol
