    Ok, here's the deal, if all goes according to plan, I'll be buying an STi by summer. Now all manufacturers have their break in period saying to take it easy for the first thousand or couple thousand miles. Anyway, I think it was on honda-tech.com that someone had posted a link of some guy who had supposedly done this with like hundreds of motors, and that is he ran them hard for the first 20 miles so that the rings would seat nicely, and then the break-in period is over and you can drive how you like. So anyway, my dilemma is this, I want to know if that guy is just full of it or what. If anybody has read it or even has the link and can help me out, I'd appreciate it. Thanks.

    this is very true
    i read that guy site
    he does a couple full bore red line runs etc etc and swears by it

    i personally know diesel shops that do the same thing...
    when they rebuild a motor and start it they run it at redline for 20 minutes...
    they say that most employees or companies will not let it warm up before going right to work so they break it in like it will be used for the rest of its life...
    that makes sense

    but you will have a warranty
    and new ecu's have data logging of sorts
    so when the dealership hooks it up at 8K miles after you blew a rod they will know that you did not baby it for the first X miles...
    i would highly advise that you follow the dealerships advise because it can and will affect your warranty...

    if it were my car's motor that i rebuilt... i would take it easy for the first 500 to 1000, prob not going to redline for at least 2K miles... its a big investment to abuse right off the line...

    Motoman is the guy who talks about break-in that way,Also Jeff @ ImportBuilders
    Recommends the same way. so I Tried it and it works my motor runs flawless after 4K miles on it and no oil consumption problems!
    Go to importbuilders.com he has a write up about it.

    the hard break in works VERY well

    there is a difference between beating on an engine and driving it hard

    A lot of amnufactures break in the engines from the factory but its the rest of the car supposively that needs to be broken in.

    i run the motor kinda like im but do it in steps. base line and tune for idle 20mins, 50 % throttle and tune it / set up and check all boost levels and fuel ect, then its 75% and check the motor/ boost levels and af ratio, then its balls to the wall, takes a good day to break in the motor but so far i have been blowing a motor up every 2 mnths instead of every 3 weeks

    the only thing with that is that i'll be buying a stock STi, so it's not like i'm buying a rebuilt motor, it should already be tuned and ready no?

    just buy one off lease or a year old, let some one else break it in for you
    and get the extended warranty
    lol

    a (4 stroke)motorcycle engine is just like a car engine
    they both have pistons
    they both have piston rings
    they both need their piston rings to fully "bed in" and seal well for optimum life span and performance


    hard break in = :thumbsup:
