i did mine the same way as josh and ran the car for two years like that with no problems...
the wheels on the little ihi turbos have marks on the backside where they were balanced..
there not balanced on the turbo...
if they were, how did they put the marks on the backside of the wheel from balancing???
if you clip a wheel, or do any other mods to the wheel, then the wheel needs to be rebalanced
the turbo dosent get balanced.. how do you balance a shaft running on journal bearings that fill with oil??
there not ball bearing turbos.. there tolerances are surprisingly loose.. but the wheels are balanced way before there put on the turbo...
ive put this one on that, and that one on this, and ive never had an issue...
