38r ball bearing balance after wheel swap.
So this is for new folks.
Over the last few years we have seen many ball bearing 38r units fail from swapping on an aftermarket compressor wheel and not balancing the turbo.
The ball bearing turbo absolutely REQUIRES a balance after a wheel swap. If not they will usually fail in 10-15k miles. This costs 4-500 dollars.
So adding 6-700+ dollars to swap on a different wheel is not cost effective on a $1200 turbo. Not to mention the oem 66mm wheel on the 38r’s is more efficient everywhere but at high rpm full throttle.
The stock journal bearing turbos do not regularly suffer from this issue. Very few journal bearing units have issues after a DIY rebuild and wheel swap. Not saying it doesn’t happen but it’s rare.
