Boosting my tc, currently torn down to bare block, going cp pistons, k1 rods, and a balance shafts delete, do i need to rebalance my crankshaft? looking for any info with anyone that has a similar setup

 

Any time you're changing things in the rotating assembly, pistons, rods, etc., you should get everything re-balanced. A good shop should be able to get you within a few grams of balanced but you're going to need to provide all the parts you'll be using, including rods, bearings, pistons, rings, piston circlips and on and on...
