Is High Reving Harmful?
Is it bad to redline your engine on a daily basis? How would it affect long term engine life? Will I see 150k-200k miles?

IMO it doesn't hurt the engine one bit, that's what a rev limiter is for.

ya rev limiter is set at a safe limit for your car. But maintainting your car is all on how often you check or change your oil and such.

Engine wear - or the expected mileage out of a car is a function of mileage, nr of winters, maintenance, average RPM, peak RPM, the distribution of engine load over total engine's operating time, number of startups, minimum temperature, maximum temperature, commute distance and hours, traffic conditions, intervals between consecutive startups, quality of roads driven, altitude, elevation, air pressure, and humidity.
Add to that the impact of the driver's age, health, skill, marital status, temper, the personnality of your significant other and the number of kids. To make things worse, a lot of the aforementioned variables are mysteriously correlated with the others (a temperamental driver with a bitchy wife and screaming quadruplets might vent on the gas pedal more than a 85yo zen retired hippie). Bottom line is that you won't get a satisfactory answer. Search the forum for mileage tales. Lot of cars driven like they've been stolen with litle problems and big mileages. Lot of stories of babied cars which kept having issues too. |

In general, I'd assume if you treat it right through regular maintenance and even some preventive maintenance (replacing things before they call to be replaced) you should get a good 150-200K out of a Subaru engine, or really any car. Pair that with babying it, and I think you have a good recipe for success.
Now, no maintenance and babying it... yep, gonna lead to problems. Maintenance and gunning it all the time means more maintenance, which if you're following Subaru's guidelines maybe be not enough maintenance for the driving conditions... hence why engines sometimes fail. |

simple rule to engines: Higher rotational speed - higher friction
treat your car accordingly, just make sure you have an adequate amount of clean (enough) oil, for the most part that is all i would worry about with a stock set-up |

Please just make sure you do your high revving when the engine is warmed up. Cold, thick oil is what destroys engines.

The engine only produces power to a certain rpm, anything after that is just wasting gas & creating friction

120K on my 98 2.2L... drag raced, Road Coarsed, Auto-x, and wangan (lots of it). i have a 4EAT and yes i shift it like a manual when driving hard.
replaced Head Gaskets (due to them being blown) at 78K miles. replaced with cometics, no problems since. transmission works just fine while on the highways doing high speed runs yes i have pinged the rev limiter a bit... but i never ride it. car revs to 6200RPM |

Also: A redline a day keeps the carbon away! There's a difference between driving spirited, which will help keep things inline, and genuinely beating on it, which will just bend crack crush and destroy your expensive toy. |

More issues arise when a car is driven irregularly (IE not often, and not hard) than if a car is driven hard regularly.

I know I should have short shifted in my video but I was against the dreaded 89 civic and once I was in the slalom I was not shifting.
The motor that was damaged is in for a DSP build, with a higher limiter on the tune |

figured i would get a little flame for that use of word but oh well.. basically yes I-94 at about 2-3AM in the morning having a little high speed fun (though 114 limited isnt exactly high speed) the main point i am trying to make is that i have in my opinion beat the piss out of both my trans and motor and have suffered very little. though mind you i do not promote nor condone street racing and/or its lifestyle Quote to get flamed for "if they didnt want or expect me to drive over the posted speed limit they wouldnt have allowed my vehicle to do it in the first place" |

I can attest to this. My car's been sitting for about 1-2 weeks. It's leaking oil kinda bad. If I drive it, it doesn't leak. It makes no sense. |
