it all has to be balanced at 130000rpm or it will go bang.
Cheap price for a a T34.55 turbo even tho it needs a rebuild.
Good luck.
no offence but this isn’t my first turbo rebuild. I’ve rebuilt far smaller/balance sensitive turbos. In fact the first turbo I rebuilt was a little borgwarner k03 which is still going strong today with 3 years of abuse at 22psi on it daily.
If every rotating component is kept inline there’s no real need to rebalance. Only if the comp/turbine wheels are changed, damaged or misaligned. A simple journal bearing change and clean up will have next to no effect on balance.
Besides if it does have a balance issue it’ll only knock the bearings out quicker at which point I’d chuck a new CHRA in it as they are about the same price as sending a turbo off to be rebuilt for me.
£30 for a rebuild kit. £200 for a CHRA. I’ll rebuild it myself first and see how it goes, I’m not a fan of getting other people to do work I can do myself
