oh yea i had a built gsr that was all motor with a turned crank with oversized bearings. i turned that car 9800rpms almost everyday i drove it. when i got bored and tore it down to look at the bearings 6 months later they still had the coating on them and looked almost brand new. its all about checking all of your journals and and then measuring your clearances bro. do it right the first time or do it again ya know.
