hey guys i need some help on this

well i am doing a turbo build with my a6 block i got the low comp/bigger piston and i honed and bored my engine block out.

now the guy at the shop is telling me that i should get my engine balance. but a lot of my boys told he that u dont have to balance honda engines like they dont need to be.

SO WHAT DO U GUYS THINK?????

was there anything wrong with the block when you took it apart?

if it was in good running condition before you tore it down then i dont REALLY see the need to balance it if your just putting in new rods and pistons with a quick "freshen up" of the block.

sounds like another expense you dont really need. :TU:

you said you are gettin bigger pistons... how much did you bore the motor out? The sleeves tend to NOT like that on a turbo build...

the moter was like brand new i had 76k on it and i bored it out to 75.5mm so i only went .20

but i do have to get the block under cut so the pistons will spin freely but still i wouldnt have to right?

you mean so the rods will spin freely?

If you say that the motor was in good shape, then i wouldnt worry about it too much. You may need to get your crank micropolished or something.

here's a couple of jewels for you.

Hello. The parts that move up, down and rotate are balanced. Pistons and rods are balanced by making them all weigh the same. The rotating parts are balanced by making all sides weight the same so one side is not heavier than the other.

now Honda crank; you will find it better balanced and more accurate than most machine shop balancing machines can accurately balance.

It is good to balance your engine in general when blueprinting it but this is a completely different matter than balancing the crank.

now i'm buying aftermarket P29 pistons w/wrist pins and shit. i want to make sure that they are well balance per sae and i'm not trying to do anything more than is needed. but if i'm going to spend a shit load of money on my motor i want to make sure that the fucker doesn't vibrate what so fucking ever. and everything is some what close to perfect.

when ever you change pistons, rods, or a cranks it is a good idea to have them balanced. not all of them will way the same so this way when you do put it together they will and one less thing to worry about. how much is the balancing might i ask?

thanks for your "jewels"

hello........... i know.

but he stated that the engine had 76k on it when it was disassembled and was in fine working condition. if you are going to the extent of having you block blueprinted then obviously it will also be balanced. i.e the term "balanced and blueprinted".

if your building a 400+ streetwhore monster, then yes, i agree.

but for the most part its USUALLY not necessary in this type of "mild" build.

and if you buy QUALITY parts, they are all balanced from factory. (eagle,pauter,wiseco, je...etc..)

it is probably not required, but if i was replacing any part of the rotating assembly, i would want to get it balanced just for piece of mind. the rotating assembly is balanced from the factory, but you are changing part of that out so it is different now.
