Balancing the bottom end... how far would I have to go?

my point excactly. However i was under the impression that you can balance, crank/flywheel and pulley alone, so that whenever you end up changing pistons/rods you dont have to do it all over again providing that the pistons and rods are equal in weights and within parameters.

JP explained it a bit to me but i thought of posting here as well.

All the 5 cyl flywheel are from the factory unbalanced at U=213,2cmg +/- 10cmg. This is the specification from Audi i have been told.

And this is the the technical drawing from Audi (unfortunately the picture has bad quality).

I've been round and round in circles with this one many times Ross. Whole lot + rods + clutch is the only thing that makes long term sense. Save up for it rather than rushing and regretting your decision.

BTW, you've chosen the same power band that I have concluded to be the optimum for the budget conscious...

How critical is the bottom end balancing? Would only swap the rods to H-beams. Of course I change new bearings and seals, but maybe also a lightened cr-mo flywheel...
