Personally, I would sleep better if everything was balanced. Crank, rods, pistons, etc...

every one in here gonna tell u to balance it.

they will not answer u, cuz they didnt try it.

if ur rods and pistons weight les than the factory, ull be fine.

eagle rods small and big ends weight les than the stock rods.

and allso wesico pistons weight les than the stock pistons.

turst me ull be fine.

Ideally you balance the rotating mass to 0 grams which means: the clutch and flywheel,crank,rods,pistons and crank pulley.It keeps harmonic vibrations down by doing this.Hence the term "balance" in the commonly reffered to process, "balance and blueprint".

think its just good practice to balance on a V-motor. Not as necessary on a I....at least to me

I know some people don't, but we don't put engines together without balancing. And matching weights between pistons and rods is not balancing.

Would I loose sleep if I knew my engine wasn't balanced...probably not. But if you are the point of deciding balancing vs. not...then I suggest doing it.

If everything is very, very close in weight relative to each other, then you're probably fine.

But it's not really the weight itself more than the weights relative to each other. Pick two of the lightest piston and rods together and two of the heaviest piston and rod and you might have inbalance inbetween those to that might not be favorable.

I don't think it would be THAT hard to mix/match piston and rod combos and try to get the whole set's weights as close as you can relative to each other. I mean w/o resorting to grinding grams of weight off of stuff.

^^^Please this thread is being loaded with completely inaccurate information^^^

Again, matching weighs is not balancing. If you hang heavier than stock or lighter than stock components on that crankshaft, you need to balance it...period. And since 95% of the aftermarket pistons and rod sets will be heavier than stock, you need to balance.

Didn't say it was balancing. Just hoping that guy's installer tried to make it as "balanced" as possible with the parts he had.

Yeah....this thread has potential to be very informative for people but there is some sketchy uninformed advice in here.

Sharif is right....I wouldn't lose sleep on one of these set-ups but if you have the option or choice...why not? That doesn't make much sense.

It should also be noted there are different degrees of balancing components as well. Naturally the more extreme the set-up the more extensive it should be.

Balance is the key to 30K boosted miles w/FI and no problems.

I agree, balance is Key
