<div class='quotetop'>QUOTE(sabzi5858)</div><div class='quotemain'>a little bit of vibration vs. higher risk of pistons meeting the valves.. hmm.. i think that's a no-brainer..
most agree that it is worth it to make the engine just a little bit more reliable. Â*don't believe any of this crap that you hear, such as "the balance shaft eliminating kits are a joke to anyone that actually knows these cars." Â*anyone who truly knows these cars, ie. not a dime a dozen mitsu tech who only knows what he is spoon fed, but people who have actually tried it knows that there is great benefit in eliminating anything on the engine that is unnecessary. Â*especially when it is rotating mass, driven by the crank (which does mean, yes it robs HP, although minimal), and moreso when it is driven by a belt that is known to break, and in the process kill the timing belt (which i'm sure we all know what harm that causes).
</div>
obviously, youve never done it. I have. Its a rediculous "mod" that doesn NOTHING. the engines were ENGINEERED with the balance shafts. they are not internally balanced. the car is also not the LEAST bit more reliable, as if youre ignorant enough to ignore the timing belt interval, you deserve what you get.
You loose approximately 1 to 2 HP with the balance shafts in there.
of course, you ignore the larger problem of removing them. On high RPM engines, the oil pump gear has been known to wobble out the housing laterally due to the missing support of the balance shaft. Of course, you knew that because youve probably worked on what, 1 mitsu in your life?
Plus, the added vibration (and it is EXTREEMLY obvious to all but the dimmest of bulbs) is a constant source of fatigue not only to the driver, but every single fastener on the engine.
but dont listen to me, Ive only made a 430 HP eclipse complete with balance shafts thats had over 15000 hard miles placed on it without any failure whatsoever.

yeah, if you can live with having to change 2 belts everytime you do a timing belt change, and the increased chance of one of those breaking, and you are immensely bothered by a car vibrating, roaring, or showing any balls for that matter, there's no reason to eliminate them. Â*but personally, i would go with the guys who DO know what they are talking about, you know, those guys that build engines for racing, not for grocery-getting, after all, i didn't swap my engine to be able to get my groceries faster (although that is an added bonus? Â*:wink: ).</div>
hell then, why not buy solid motor mounts, spur cut gears, and just set the car on its bump stops.
i mean, you are a tough guy, arent you? Why bother using technological advancements when you can have an absolutly shitty experience behind the wheel of your car.
<div class='quotetop'>QUOTE</div><div class='quotemain'>
you know what, i'm sick of hearing all this crap about "oh, don't mess with that, mitsu put it there for a reason," or "don't you think the engineers know what they were doing?" well, the simple answer to the second question is NO! Â*just take a look through the damn recall list, try to tell me they made a perfect car. Â*and if you're gonna spout this crap about "mitsu techs know best," then don't mod your damn car unless you use only ralliart parts! Â*dealership workers are not some special, above human, superior beings, they make mistakes just like everyone else, and the same goes with engineers. Â*you wanna know what mistake they made here? Â*they didn't balance the crank properly, and so they need a stupid balance shaft to cancel out the vibrations so you don't feel them. Â*if you really want it not to vibrate, blueprint and balance the crank, that would actually be a good thing. Â*do you honestly think that a mitsu tech, in the USA where we have no race support from mitsubishi, is going to know a damn thing about performance that someone else wouldn't know?
</div>
you really are a fool, arent you?
suit yourself; "mod away". Ill be laughing at you from the end of the track with my car thats pleasant to drive and doesnt break down.
by the way, mitsu patented the balance shaft in 1971. EVERY car company uses them today, and everyone needs to pay mitsu for the right to do so.
of course, you know best. every car manufacturer must be wrong. people love vibration.
<div class='quotetop'>QUOTE</div><div class='quotemain'>
mitsu may train its techs to diagnose problems, but we have good people in our dsm community who have dissected, and built up numerous engines, and can tell you a hell of a lot more about the mitsu engines than any mitsu tech would ever be able to tell you. Â*and Â*probably even more than a mitsu engineer could tell you (after all, he is legally bound to keep the plans from getting out, after all, they wouldn't want us to find out the true cause of crankwalk, now would they?)
</div>
when any of them build a reliable 430HP 2.0 liter using stock parts and DONT break it, you can say something.
till then, I suggest you shove it.
I love the conspiricy theory, by the way.. makes you sound even more rediculous.
<div class='quotetop'>QUOTE</div><div class='quotemain'>
the people who say don't get a balance shaft eliminating kit in a daily driven car better not be getting prothane mounts either. Â*your stock mounts are soft for a reason, to keep you from feeling the engine vibrations. Â*sound familiar? oh yeah, that's what the balance shaft is there. Â*and you better not stiffen the suspension, because the stock suspension is like that for a reason, to keep you from feeling the road vibration. Â*and don't forget suspension bushings, and shifter bushings.
</div>
exactly. these are daily driven cars. not race cars.
<div class='quotetop'>QUOTE</div><div class='quotemain'>
btw, a lot of people would install a balance shaft eliminating kit in a daily driven car, and to top it all off, they (the good ones atleast) are made with mitsubishi parts (as JIP said as well)!
did you ever stop and think, "hey, maybe the real reason is stupid?" Â*for example, maybe the reason is to save money, by putting out sub-par parts, like a poorly machined crank, and then hide it with a balance shaft so people don't complain about vibrations? Â*incase you didn't notice, these cars weren't given to us in a performance orientation, if you want it to perform better, you have to change a whole lot of crap from how it was stock.</div>
you have no idea how cars actually work, do you?
apparently not.
Never mind the fact that 4 cylinder inline engines are naturally unbalanced. never mind the fact that you CANT eliminate all 1st or second order vibrations from one without balance shafts. lets just take out parts for the helluvit, 'cause it may gain 2 HP.
also, if you want a performance car, why in the hell would you not buy one initially? thats like buying a corvette, then bitching it doesnt hold enough people.
