Default G-pop high performance vs regular kit

I just bought a journal bearing t25 from the zilvia.net forum for $60. It has minimal shaft play but I still would like to rebuild it before installing it on my car as I don't know how the seals are.
Now, G-pop sells the regular kit for $85 and they high performance kit for $155.
From their website "High-performance rebuilds include a stepped-gap piston ring instead of the standard piston ring (if your turbo model has this option), as well as a heavy duty steel 360 thrust bearing instead of the 270 bronze thrust bearing"

Do you guys think it is worth spending the extra money for the high performance kit or would the regular kit be good enough. I plan on running it on a stock 1.6 at a maximum of 12 psi, I just want it to be reliable and last a long time.

Also, would you send the chra to get balanced? I never used the turbo and have no way to know if it has been rebuilt in the past

I searched on the topic but couldnt find anything.

Thanks

Just buy the basic kit. I rebuilt my t25 like 50,000 miles ago and have yet to have any issues.
Balancing? Not necessary, just don't bend any fins or anything and you'll be fine.
Samnavy has a great write up on how to rebuild these turbos. Check it out.

Thanks! I did read the sticky on how to rebuild. I feel like using a bronze bearing would make the shaft last longer, steel on steel may lead the wear on the actual shaft. But I dont know what grade of steel the high performance bearing is.
