just using ls rods and je pistons into a z6

 

You want to balance the whole assembly. Not just the crank.

 

yeah, that includes pistons and rods right? and how much would that estimate to?

 

to get all the vibrations out and have everything balance outand spin freely, and less wear on your bearings...

 

These motors come balanced so well from honda. I bet the machine shop does'nt even have to touch it. Just make sure the pistons/rods are equal weight.

 

Have it done anyway.

Thats all I did when I installed ctr pistons in a b16a. Since it is an upright engine all you really need to do is make sure the pistons/rods are with in a couple grams of each other.

 

If you are building an engine and dont want it done, you dont have to; but why skip something so important?
If you've ever heard,felt, or DRIVEN a WELL balanced 4-cylinder, youd know what difference it will make. The motor sounds different, rev's smoother, and gives you a huge peace of mind.

The things you need to have balanced are: Clutch, pressure plate, crank, pistons (with pins), rods (with bolts), and the crank pully. This isnt too pricey and you WONT regret it.
