Streetport service of all intake ports, and all exhaust ports. This is the single largest gain you can perform for the Rx8 engine. I have seen dyno gains of 20hp. This retains factory smooth idle and driveability on the street. Does not effect reliability.  Will require a re-tune of the factory ecu to see the power gains. If left stock a streetport will run very rich and may produce less power than stock.
