To what tollerances do the connecting rods need to be balanced to? 1 gram, 0.1 gram, or 0.01 gram of each other? Thanks

as close as absutely possible!

 

good answer..

 

Don't know if it helps, but ITR rods are balanced so well that the weight difference is neglible!

Is it necessary to balance with the crankshaft?? I've only balanced the pistons and rods.

 

for the reciprocating end and total rod weight as well as the pistons, its good to have them within a gram of each other. no, inline engines like honda do not need bob-weights to be added to the crank when balancing, its only used when balancing a v6/v8 crank

well, i disagree with that.
i've seen a few sets out as far as 5g

 

I'm so lucky that my rod weight difference are under 1g. Mine's are JDM 96spec engine.

 

imo yes

 

wow, rods that came in the same motor ?

guys at the plant must have been sleeping that night ... thats careless especially when it came to those R motors.

yep.

 

That's why we assemble our motors... We are just waaaay more CAREFUL/PICKY then those ***** at Honda!!!! hehehe

 

However, I found the weight difference of piston are more than 3g, one of the piston had 5g difference

 

The electronic scale I have is acurate to 1gram. This should be adequate for balancing right? Also, Where do you remove metal from a piston when balancing? Thanks

Both local builders that I've talked to recommended taking it out of the inside/bottom of the piston....providing that there's enough material there to work with to drill out a few spots.
