fanman, what you say about the low end is true.... but short of piggyback fuel/ignition controllers, you can throw every imaginable N/A bolt on at this motor and not see more than 20-25 horses gained even in the upper end of the power band, and thats if you're lucky
so its not that there is nothing to be gained.... but 20-25 ponies for hundreds to thousands of dollars invested.... dunno bout you but i call that negligible I think this notion will soon change. Mazsport has dyno's up showing 20 rwhp with their Ignition upgrade and Int-x alone. you can't tell me that intake and header-back catless with pulleys will only add up to 5 hp. I think sometime in 08 we'll see a bolt on NA 220 rwhp RX*8. Thats like 40whp or roughly 50 at the flywheel for $5kish. |

Air intakes, hi-flow cats, cat back exhausts, pullies, ecu re-tune, etc all just amplify the NA engine's character...that there is little low end power, with the engine coming alive in the upper rev range. |
whats the diffrent between a brand name intake and a auto zone intake just change the filter with a k&n??

FWIW we saw a NA 220rwhp RX-8 in 2007, with an OE ignition system and emissions legal too ...
