Hello rotor heads, I'm new here but not to rotary engines or rx-7's. I would like some advice from people with experiance (engine builders, racers, street tuners ) in apex seals. I plan on a 91 turbo II rebuild soon, large street port, Wolf ems, stock turbo (gtx) for now and upgraded intercooler (the rebuild / upgrade list goes on and on..). I dont plan on running extreme boost levels (10-12psi) yet but am having troubles deciding on apex seals. I plan on 3 mm but thats it (for insurance reasons). I'd like good sealing charactoristics and minimal wear to the rotor housings. I'm guessing 2 piece would be more efiecent for low rpm sealing. I want something robust and want it to last a long time (goal of a 300-350 fly hp motor to last 100k miles) this will be a daily driver. Any input will be appreciated!
