Racing beat won't do it. Pineapple's phone is busy. Too late to call Pettit. Anyhow since the 8 rotors are (lighter &) higher compression the 3mm NRS seals should offset that a lil bit (but not sure by how much) and also low boost (10lbs). If it needs to be milled for taller seals then it won't make a cost difference to mill them for 3mm.



There is only one person I know of that has used RX8 rotors in a RX7 but he is no longer with us and I do not know if he used RX8 seals or not.



Any help on this from the engine building experts? https://www.nopistons.com/forums/pub...IR#>/blink.gif

you know you can get lighten the older style (none rx8) rotor even lighter than the rx8's aye

Yes, I know I can get older lighter high compression rotors but they won't be anywhere as cheap as RX-8 rotors. I'm not sure if milling would offset the discount.

cant remember where i read it but im pretty sure you have to run the older style seals, unfortunitly i dont know what sort of price you would be looking at to get them milled
