wich one? bigshaft or standard

[CyberManiaK]

Hi i'm building a T3/T4 with trim super 50

but i notice that there are 2 number parts for the compressor wheel.

20576 and 20576T the 20576 stands for a standard shaft and the 20576T is for a big shaft. and the problem that i have is wich is the one i need. the T3 side is from a T3 chrysler. i would need the standard or the big shaft ? i ask this because here in mexico anyone know wich one is the one i need.


Thanks a lot

If you are retaining your stock turbine from your t/3 you
have a standard shaft (smaller).

Thanks well i was retaining the stock turbine but now some shop's told me that the wheel i'm looking, is not on the market anymore. but they didn't told me what i need to upgrade so i can put the bigshaft.

You can help me with that ?

To run a big shaft turbo, I believe you need a new center section along with the turbine wheel/shaft. It's not really worth it if you ask me, you could get a dual ball bearing cartridge for around $700 with your choice of both wheels... brand new from ATP turbo.

Turbonetics has changed over to big shaft for their hybrids from what I have been told. I tried to track down a super 50 wheel about a year ago, and I could not find one new.

As previously mentioned a new turbo might be your best bet.
