have blown apex seals in rear section of my 86 rex(non-turbo)....what my question is; is interchanges??....have come accross many turbo II parts like housings,rotors, etc. will these parts interchange with a non-turbo??? and what size apex seals does a turbo run???.....2mm or 3mm.....

 

Rotors and housings are different from NA or Turbo models. The apex seals are the same for any 1986+ mazda rotary engine: 3 piece 2mm
