turbo problems

[tikt]

Hi i brought a IHI VF-34 turbo off ebay about 2 months ago for my v5 wrx sti,

after install when i started it there was a puff of light greyish smoke and it happened sometimes when i started the car ( sometimes after short periods off and sometimes long )

i got an aftermarket link ECU and got a dyno tune for the new turbo ( they removed my air flow meter as i was told it was not required)

lately when i have been boosting over about 12 psi a whine noise starts and the turbo then cuts out then kicks back in when the boost lowers a bit.

so im assuming the turbo bearings and seals are stuffed

i have done a lot of searching of forums and i have read that they can and can not be rebuilt, does anyone know of a place i can get this rebuilt in NZ or even overseas i am not too bothered on price as long as its cheaper than a brand new replacement

thanks heaps

a vf34 should be fine for 12 psi.im sure that turbo would be sweet on 20psi.are you sure its your turbo thats blown?

My 34 is running like 21psi no problems.

Note that they do whine just a little bit due to ball bearing center.

Did you reduce the size of the restrictor on the oil feed banjo? If you went from an early journal bearing turbo to this and didn't change the restrictor it's possible it will be over-oiling and pushing oil through the seals.
