1.3 bar is a bit much for the bearings to handle the turbo on the friends mr2 lasted about 12 months of hard driving (drifting)before a blade fell of the exaust wheel and when rob at turbo dynamics pulled it apart to rebuild it they found that the bearing case was unrepairable because the ct26 bushes are only 320 degrees they dont last as long at higher than 13psi and the only company i have found toreplace the bushes with a proper ball bearing is blitz but the cost of that turbo is around the $4000 mark
