But the fact that they consistently have short lifespans is what concerns me. If it was just a few isolated cases of people turning up the boost without enough fuel, then I'd understand, but this problem seems to effect cars that have remained stock.
My friend got his 3rd gen rebuilt at around 70k, and they said they changed an oiling mechanism that injects oil onto the rotors. They said something about Mazda switching to an oiler that injects less oil to improve emissions, but that it had adverse effects on the reliability of the engines. So this company replaced the oiler with one that squirts more oil and they said that will help a lot.
