What are the differences between the t3 34 and 4? Do they userhe same core internals but different compressor and exhaust housings? Is a T34 a T3 with a larger compressor housing, but the same core internally- are they identical bearings, shaft etc? Different blades in the compressor wheel?
And is the T4 totally different core aswell as housings?
I'm currently running an ex rally t34 but struggling to get the correct bearings internally as they are apparently non standard 360 bearing, washers and front bearings aswell as seal plate?!?

 

The core or bearing housing is the same on T3 T34 T4, it's the size, and a/r of the inducer/exducer that is different, depending on what the turbo was originally on.
Speak to Vince at CR turbo's, he'll soon help you out.

I will have to then thanks tabetha, I'm on the look out for a T3/34/4 core then, though the front bearing on my turbo is different to a STD T34 by the looks of it
