Hey guys a mate of mine gave me a blown VG30 turbo so i decided to strip it, So i thought i would post up the pictures for everyone to have a look at will help clear up some questions and settle some rumours
Blown Shaft & Compressor Wheel
Core with wheel & shaft removed
inside complete Core
Removed Cir-Clip
Fully Disassembled Core
Cir-Clip and sealing plate
Thrust plate? not really sure lol
Compressor side ball bearing looks like has experienced compressor surge or from when the turbine wheel departed from major imbalance and the bearing cage has shattered
2x bearing housings, center spring housing and locking bolt
Turbine Side Bearing still fine has couple tiny cracks
Empty Core
So as u can see these turbos are dual ball bearing
I believe they are hitachi turbos designed for nissan
i also know that all these turbos run the same size turbine wheel so all turbine housings are interchangeable
also the casing number (eg.45v1-45v4) on the RB25,RB25 NEO & VG30 Compressor housings mean nothing as i have seen VG30, R33 S1&2 and R34 turbos with the same number.
hope u all enjoy these pictures thanks for looking
