Few things, I imagine most of the components are slightly different, it has a different gearbox (from the valver I think) and no intercooler.
MERCEDES CLS AMG
kkk turbo fitted to both
K9K 704 65bhp - smaller turbo model
K9K 702 80bhp - bigger turbo model
As above - runs same crank, pistons, manifold, fuel pump etc
Ironically the slightly higher tuned motor is a hell of a lot more reliable

The 65BHP is fitted with a KKK 5435 970 0000 unit
The 80BHP is fitted with the slightly bigger KKK 5435 970 0002 unit
The 80bhp was derived from the 65bhp version, the 80bhp version of the K9K engine includes specific developments in the areas of air supply and injectors + the intercooler allows the temperature of incoming air, and therefore of combustion, to be reduced, to the benefit of efficiency. The intercooler is associated with a new setting for the turbocharger wastegate allowing higher boost pressure (1.2 bar maximum compared with 1.05 bar for the 65bhp version).
The injectors use the same technology as in the 65bhp version, but they have been developed to offer a higher flow rate. The holes in the injector nose in the 80bhp version are therefore larger, allowing a 15% greater flow rate by comparison with the 65bhp version

Matt your guys helped me out big time with a couple of springs the other week, kudos.
65 runs 1.15 bar boost depends on rpm but that about what it stabiliises at.
80 runs about 0.1 bar more.
65 doens't have an intercooler
The 80 have the intercooler and a bigger set of injectors plus mapped and a different gearbox that all ther differences though engine are much the same realy.
