Thanks! I’m not sure what people expect from these engines- they’re somehow basically the most reliable car engine from that era (they regularly came out at the top of reliability ratings), while still making ~1.5x the power per displacement that was standard at the time. Things like the D chunk failure and IMS failure can happen, but most people will get a reliable 200-300k miles before they do, and the IMS can easily be prevented with a new bearing kit that is fairly cheap and easy to do. The 2.7 Boxster engine had none of the cylinder issues- that’s the Porsche to get if you want low hassle fun transportation IMO.
It’s true they’re expensive to rebuild properly but you can get used engines with a lot of life left for just a few k.
