boostisgood said:RX-7 had overheating issues, and the forced induction did not help it much. Any time you increased boost more then 3-4 PSI over factory, you ran the risk of blowing APEX seals.
The Renisis is a total redesign of the old 13b. It is more efficient in the cooling dept, and from what the Mazda engineers said about the engine, it can take a few psi of boost.
