it is not a ball bearing turbo...
if you really want to push it correctly do a work ->ported and polished your head and a good cams with uprated vaves spring and if you are not affraid use the 5efhe high compression piston.. you will push it !!!
i have a turbo manifold for your turbo if you are interested ..:shoot:
mate i already using it now....... it its doing the job very well :rockon:
but i need to rebuild it because its smoking
thats all i was asking
i found one guy can rebuild it but he said i will do it if it non ball bearing turbo
but the bad luck its ball bearing
so he will try to do somthing
he just told you that its not ball bearing!
