Message	Apparently you generate high side loads on the ceramic ball bearings when you try and get more boost out of the GT series turbos than they were designed for; ie. overboosting. Conventional turbos w/the bronze shaft bushings aren't prone to failure as quickly when overboosting. Dave (CA) 95 TTz
