I had heard that I'll need the water pump from my 1.8 as it goes the other way but are there any other problems like height, oil filters, engine mounts, clutch/flywheel (got a lightweight f/w and racing clutch in the 1.8 and would like to keep them)
Also, what about a from legal standpoint? Obviously I need to inform the DVLA and insurance about the new engine number/capacity. Does a newer engine affect the emissions test at MOT time? (officially that is, I'm sure my local 'friendly' MOT center will not be too worried about the emissions...

TIA
