Rotating assembly.
I have searched and I still get mixed answers on this. I am building my D15B (TT rods, Vitaras, tougher clutch, lightened flywheel). I know that getting everything balanced together would be a good idea, but since this is a budget build is it absolutely necessary? Would not balancing cause my motor to spin a bearing much easier, etc?
I'm still very new to this engine building stuff. It's my first time inside a block and whatnot.
If it does need to be balanced can anyone recommend a good machine shop in the Jacksonville, Orlando, Daytona areas?
Thanks for the help.

Re: Rotating assembly. (JShull)
At the least, you want the rods and pistons balanced w/o half a gram of each other. The next step would be balancing the crank (by itself), then the final step would be having the counter weights reshaped to better accomidate the heavier components. Usually that requires adding material, which isn't acceptable.
As per finding a good machinist, try finding a shop that has a good shop-owned race car(s), that also does lots of hondas. Ask them who they use.
The place I used balanced my d16 crank for like $50-75, but they told me it probably didn't need it (based on how well it was balanced from Honda) unless I was revving past 8k daily.

Depending on the quality of the parts your using (pistons, rods) they should already be balanced. And FYI they dont balance your rotating assembly together, they balance the parts individually.

Your right, BUT it doesn't matter. You want the rotating assmembly balanced. They balance the counter weights compared to your piston/rod/ring set up. It really helps for longevity of bearing life and such.
