The water pump..

RB30 and N1 pumps.

Interestingly, here are 2 photos. One is the RB30 and one the RB26. Notice how much taller the block is from the block deck to the top of the water pump. The RB26 is flat and the RB30 is 40mm taller.

RB26

RB30

The next problem is the gearbox bellhousing bolts don't line up with the sump due to the fact a sump adapter is used.

To get round this problem, I chose to blank off the holes in the sump and start again. I also pluged a tapped hole and a plain hole in the gearbox too.

The hole are 10mm out of position, the thickness of the sump adapter.
