Three of the injectors are definately on different pins, but they are just mixed around with each other, this is why the engine still ran, the injectors would be firing at the wrong time, but the timing is so close, it still ran under no load.
If you drove it like this you would definately notice it.
Also I have found out through someone in the forced induction section, and confirmed it with the R34 service manual and Stagea S2 service manual, that the VCT is basically the same between the R33 and R34, it's ON/OFF. The only difference is the R34 has been designed so it comes on alot more smoothly.
There are a few sensor differences aswell, but from studying the service manuals, they won't make any difference to the running of the engine. I think they are mainly to do with the more intricate R&R mapping that R34's have.
