    i am going to be swaping in a d16 that has been bored out and was wondering if it would be better to break it in with the turbo on it or can i break in the motor and put the turbo on later with out any problems??

    Dont break it in with the turbo on it. Break it in N/A then put the turbo on.

    yes, i would suggest that you DO NOT put boost to a new motor until AT LEAST 1500 miles. after 1000 miles the engine should be 100% broken in, but id play it safe at 1500.

    Like Blanco said above, read that article, it is very informative. Me personally, I suggest breaking it in off the boost, or with low boost, meaning 3-5psi. As far as a break-in method, I do as I was taught in technical school. Accellerate from 30mph to 50 mph in third gear (if standard trans.), and off the throttle at 50mph and let it drop down to 30 mph on its own. Repeat this 10 times or so and it will seat the rings properly. After 500 miles, change oil and filter. After 1000 miles, change oil and filter again and inspect for metal shavings (which is normal, but should be minimal). I always use a magnetic drain plug if possible.

    Well if you keep going from 30 - 50 in 3rd gear wouldn't you not just be breaking it in with the 3rd gear's pull and could this affect the other gear to not be broken in???? Why don't you wanna break it in with 1st than 2 second than 3rd ...etc

    You do it in 3rd gear to apply a safe amount of load to the engine, and you dont risk over revving it and messin up all the work you just finished.

    You can call me dumb but I have never heard the phrase don't cross the streams. Are you referring to don't cross the line????

    You do what i mentioned about 10 times, thats it. As you are deccellerating from 50mph to 30mph, something occurs in the cylinders called "vacuum". This is what seats the rings.

    No blanco the picture really didn't help me out. I have never used that term of analogy. Well basically all vacuum goes into the cylinders on Accel and Decel. Thats why at WOT you will see 0" HG which is actually 29.9" Baro because at wot the vacuum is held in the cylinders, am I right and understanding this correctly????

    I love how Blanco's advice goes unheeded, even though he is like a God. Read the article Blanco posted already.

    LMMFAO! HAHAHAHHAHHAHA! Another classic quote that I may quote you on someday, with due credit of course, Scott. hahahahahhahahaha Beware the minions of Gozer. (forgive me if I misspelled that)

    On a different note, do yourself a favor and read the link. You could just "blow the engine up" (Blanco 2008) if you'd like too, but that wouldn't be as much fun I would think. :D
    I like to refer to him as the Don Juan of HS, Chaz. Perhaps even Don Corleon. (forgive me Godfather if I misspelled your last name)

    i cant believe that someone didnt get the "dont cross the streams reference".


    "there's something very important i forgot to tell you"
    "what"
    "dont cross the streams"
    "why"
    "it would be bad"
    "i'm fuzzy on the whole good/bad thing. What do you mean, 'bad'?"
    "try to imagine all life as you know it stopping instantaneously and every molecule in your body exploding at the speed of light."
    "total protonic reversal"
    "right, that's bad. okay. All right, important safety tip, thanks, egon.

    ahh, how i love 'working on fridays'

    I have STM so thats probably why I dont remember lines from that movie. Ya thats what I told you blanco, I said should I use the throttle % from the dyno steps for my street break in. Or maybe I didn't word it right but thats what I was asking and than I said whats the difference between to 2 but its all good. I'm 100% clear of that now. Thanks for all the help guys. Blanco have you ever thought about getting some sun cause not one very white person can look the greatest lol I mean look at your avatar, thats probably how you look in reality but obviously with white skin. JK but just a thought;)

    Sonofa....I forgot to quote him instead of you. haha Forgive me Don Corleon. Trust me when I say that you have done me many favors, especially in sharing your wealth of knowledge.
    May the Schwartz be with you.

    Would it be politically correct to give someone a rep point, just because they hit the nail on the head in quoting Ghostbusters? haha That was great man. :D
