I agree that if they were going to do anything, they'd increase the bore, but a 4mm overbore would be a pretty significant operation. I don't know if the materials permit.

When I say "I don't know", I mean that literally, not rhetorically. I have no idea. Does anyone know if the cylinder liner thickness in the N20 would permit a significant overbore without changes to the block?

EDIT: I would like to point out that a 0.050 overbore would be considered on the high side for most engines. That is 1.27mm. I would be very surprised if the N20 could be bored 4mm.
