I would fully balance anything that goes in the engine, new or old.

It's been a few years since I last had this done and local rates can obviously be different.

I think having the rotating assembly ballanced was a couple hundred dollars.

If you have a good scale (10th of a gram), you can do the pistons (with rings, pins and clips) yourself. The rods really should be done by a shop with a fixture that allows them to get the end-for-end balance right.

So you might be looking at $300. None of this work is VW specific, so you can shop around a bit.

The difference between a well balanced engine and one that is not is absolutely something you will feel. If you just bolt random parts together, you may or may not get lucky.

VW did not carefully balance each assembly. On an assembly line, that would take to much time. Instead they sorted rods and pistons into weight groups. Each engine got four pistons from a single weight group and four rods from one weight group.

And of course the original balance specs were laughably loose by today's standards. For example (and if I remember correctly), rods only needed to be within 5 grams of each other.

Now, if I were building engines to sell to people who wouldn't know the difference, I probably wouldn't do this. It would make my engines more expensive and I wouldn't be able to sell them to people shopping by price.

But I don't build engines to sell them. I only build an engine when I need one for myself. I can spend as much time as I need to get the engine I want.
