Attesa Pump Interchangeability

Does anyone know if non v-spec pumps from R33 and R34 are interchangeable? Guessing it would be much easier to find a R33 GTR pump than a R34...

The Attessa systems on R32 R33 and R34 are all different. It could be that the pump is the same but look very carefully at how they are mounted as e.g. R32GTR  and Stagea are quite different. Maybe between GTRs they are the same but have a look before you buy one. What sort do you want ? Is it for an R34 GTR?

If its just the accumulator you need they are about $400 from Nissan (here is a part number from an old thread 41630 20U00)

I have a non vspec R34 GTR, and was thinking about trying a R33 GTR non vspec unit if they are compatible. Reason being is that R33 parts are much easier and cheaper to find. 

I have already changed the nitrogen accumulator. 

I have had problems with slow and inconsistent transfer of torque to the front. No attesa fault codes and it has been bled properly. The transfer case was inspected by simply levering on the plates on from the rear without pulling it apart, and the specialist said he doesn't believe it needs a rebuild. It has stumped everyone. 

Last things left to try are replace the pump (cheaper) and rebuild the transfer case (more expensive).

Here's an R33 one...print it out and get under your car and see if it looks the same..

Thanks mate much appreciated.
