Hi,

Just out of interest, does anyone know the difference between the N42B18 engine and the N42B20 engine?

All I can find out is that the 2L has a 9mm longer stroke, but would that really give an almost 30bhp increase in power?

Thanks

Cheers for the reply. So effectively, with the crankshaft, pistons and rods from a 318 and a remap, a 316 could have the same power as a 318? Or are the pistons the same?
