@timmy, the Tongs-turbo's also look new. Don't know if they really are new or...
I believe that the compressor housing of the GT-spec comes from a Toyota diesel that has another kind of outlet. That's why it shows the "weld".
@Turbodave, Chanced the post and did some research.
Some info I gathered:
The CT9 is a journal- bearing turbo and it uses a 270-degree thrust-bearing washer (at left). The 360 degree washer is on the right. It provides better oil disperse.
Little side note: The journal bearing is the bearing that support the shaft and allow it to spin. The thrust bearing is what takes the side loads of the shaft. A thrust bearing has no impact to spool time.
Second part from the right is the journal bearing.
@Turbodave & keirz about the the larger waste gate flap. How could you say it's not needed? Ok, it's not needed on the standard CT9. But the turbo could simply be "hybridized" so much that the maximum size you can get with the standard flap just doesn't cut it anymore. I believe there are 2 options in that case, enlarge the waste gate flap or go with an external waste gate.
Anyway, I hope the traders that sell these turbo's can get us some more info.
For example:
Dave: Can you get us more/any specs of your hybrid?
Toby: Do you got a photo of the intake side?
Enzo / Tongs-turbo's: Are the turbo's new casts or refurbished units?
Sam: What kind of trust bearing washer does your turbo use? Can you vouch for the quality of your castings to be as good or better then the genuine stuff?
