RE: American manufacuring in the 60s

The "Renesis" engine in the RX-8's was a substantial redesign of the 13B engines used in the RX-7's. In the '04's (first year) and '05's (like mine), the oil metering pump was initially set for too low an injection rate at low RPM's. Lots of blown engines on automatics, as an automatic is always going to operate at the lowest RPM possible. Mine's a stick, and I remember when I took it in for the ECU flash recall to fix this. When the service guy told me it was mostly low RPM operation that was causing issues, I told him there wasn't any need to mess with mine. :)

Beyond that, the RX-8's have garnered a bad reputation for engine reliability with a statistically high number of replacements, even to the point Mazda extended the drivetrain warranty to 8 years/100k miles just to sell the cars. I personally think they shot themselves in the foot by not advising buyers that the engine was a bit different and needed some extra care and attention. Nothing all that cumbersome, but with no effort spent to educate owners or prospective buyers, I'm sure a lot of these engines met their doom needlessly. Mine shows no signs of premature death, but I bought mine already armed with the knowledge needed. "A redline a day keeps the mechanic away." :)
