you could try 6 Port Sleeve Inserts. Like from pineapple racing or i believe Atkins and Racing beat sell them too. the New Rx8's come stock with em. and its a simple install. all you gotta do is remove the LIM and toss em in. and supposedly its an instant 5 - 10 hp increase. i can't vouch for the HP increase. but it makes sense since your smoothing out the airflow from your 5/6 ports
