Ringland Failure?
I wonder if the FR-S/BRZ will suffer from the ringland failures on the GR STi?

the 07 STi, also the only STi to have the V25 heads, were the only ones that I've known of to fail with a factory tune...so aside from that and what Dave said, /thread

Curious mode.
What's a "ringland?"

Given the fact that it's a scubby we are dealing with here. I think it's safe to say any attemp at boost on this motor will show that it does have ringland issues, and I'm sure it'll come with hypereutectic pistons aswell.

The protrusions between where the rings sit. Picture stolen from: http://www.wallpaperinstaller.com/scooby/piston4.jpg Very likely. Hell, the EJ207 hasn't come with forged pistons since...V7 or V8. |

In stock form with no turbo I don't think there will be anywhere near the stress on the BRZ engines. |

^^^well any EJ25 turbo engine can/has done it. They are all pretty much the same...pretty much. Don't feel the need to get off into nitty gritty differences for a subject that is far unrelated to this car.
