you should read up on the post by Jim L. He posted a pretty thorough step by step approach to modifying an RX7 - including all the "safety" features one should do - such as modding or upgrading to a standalone ECU, upgrading radiator, fuel pump, FP pressure regulator, etc.. to support your engine mods such as downpipe, catback, midpipe, intake, IC, etc etc etc....
