ha ha..my motor panther 150cc last time uses hi speed bearing to get pickup..these engine bearings doesnt make ur engine lighter and faster..its more on reliablity
doing some touch up on my turbo..
i using a/r 60 compression housing with 57mm wheel, turbine housing will be .55 but not really sure the turbine size..
wondering when will it spool for a 1.8cc engine?
