    You need to do some searches and read the "I want 300 whp" thread. Reliability all depends on how you drive it. There is no answer to that.

    ^this..



    I could throw out some numbers.. but that's kind of difficult to do without first knowing what engine you're talking about. "Our" engine doesn't mean much.. Mine is rated for 550+whp, but it's not stock.

    Bingo. We can't give you an answer. This is like the thread awhile back where someone asked how many miles their transmission would last. How can we possibly know that? There are so many variables: ok, the car is stock, but how about maintenance? Mileage? Mod path? What sort of driving patterns? Phase of moon? Astrological sign?

    We're not trying to be jerks, it's just reality. That said, many people have had great success with "stage II" levels in power, and "generally" have great reliability, although there exceptions both ways. Research around the forums to get a better idea what that means. Most importantly, welcome!

    if you drop the clutch and drive like a jackass, the car isn't going to last long... much like any other car. It's much easier (as far as I know) to already be rolling and do some spirited driving around some curves or whatever than running the car repeatedly down the 1/4 mile.

    It depends on how you go about making the power. If you run an appropriately sized turbo, EWG, all the right bolt ons, run e85 instead of pump gas, etc.. then I would say you could probably do 340-350whp somewhat reliably with a conservative tune as long as you don't drive it hard. Although whp measurements vary widely from dyno to dyno, and everyone has different ideas about what reliability means. I would think if the engine lasted 60k miles at 350whp on a reasonable dyno that would be decent reliability. But then we get to the question of, how many miles are already on the engine?


    And obviously no one can know.. some engines run more power for longer, some blow up during the tune. That's just the risk you take. You gotta pay to play, and it would be a good idea to have the money set aside for a built engine if you want to make a lot of power. It would probably be an even better idea to go ahead and build it before it blows up to save money and time. Then again, built engines aren't exactly known for reliability.. even at stock power levels.

    why do you need 300 HP to make you happy as it being a DD? My 07 is stock and makes me happy as a DD. Ive been throwing around the mod idea for awhile but I really don't think that I'll ever go past a stage 1. The life of the car and reliability is what I want the most out of it. If you dont plan on keeping it for the long haul then by all means throw 300 HP at it.
