some of what he is says is correct. low compression rotors will allow for more boost on poor tuning. a good tuner can make alot of power in a high boost high compression engine and not blowup https://www.nopistons.com/forums/pub...DIR#>/wink.png i don't agree with the ceramic apex seals though. stock mazda seems to be fine. everyone is entitled to an opinion though[/quote]

Stock Mazda 3 piece seals are good for streetports, not other types of porting. https://www.nopistons.com/forums/pub...DIR#>/wink.png
