Simple question that requires lots of technical experience

Is it the same size ?

Will it Mount / mate fit The same

Thankyou for all input

I'm trying to do a similar thing but into an R32. It is my understanding that all the mounts etc are the same. The difficulty is the neo is the vct which needs the R34 ECU. In my case I also want to run auto but i'm not sure the tiptronic will fit and I don't think the turbo motor came with a straight auto.

Yes it will "bolt up" to the mounts/gearbox perfectly but it wount be "plug and play" with the ecu and sensors

The neo runs top feed injectors, different manifold setup and different VCT. If you've got the complete neo harness and ecu it wont be so bad.

If you wanted to run the R33 ecu and harness, I would pull the inlet manifold off and switch it with the R33 and run all the sensors off the r33. The neo runs smaller ports than the r33 so the manifold wont be as "port matched", but it wont that bad because the manfold ports are larger than the head ports, if it was the other way around it would be a different story.
