oem crank pulley on balanced crank?

[lucas240sx]

Ive tried to search for this info but im not seeing anything

I had my sr20det crank, manely rods, and cp pistons balanced together
Is it safe to run my oem pulley or even a lightweight pulley?

Are you going to run an oem unbalanced timing chain, and unbalanced belts? Make sure your flywheel bolts all weigh exactly the same amount down to 0.000001 of a slug.

^He's got a point, it's still not going to be perfectly balanced, and I would recommend you keep the oem harmonic balancer, or even go with an ATI or Tuffbond unit.
