Exhaust setup is different and the EZL is different - 8 pin vs. 4 pin.
The temp gauge is in Celsius, and speedometer in KM although most that are imported into the US are converted to MPH.

There is typically a warning triangle on the inside of the rear deck lid.

The AC setup can be different as well with dual Klima controls.

Best for a turbo upgrade is the 500 US version: 8:1 CR. I believe the aditional boost this allows more than compensate for the loss of 550cc.

More aggressive cam profile
Transmission mode selector switch
Do all Euro 560 SECs have the more aggressive cam profile vs the US cars?

The 8-pin vs 4-pin EZL should be easy to spot under the hood for engine I.D. purposes correct?

Is the Euro LSD a clutch type and if so surely they need new clutches after 30 years on the road! Anyone know the cost for this?

Yes to the clutches in the diff thing. And the 8 pin thing being easier to spot. Not sure about the cam thing.

Did the GenII 560 RUF high compression come with the 2:65 LSD?

On my wrecking yard trips in the past, I had made it a habit to look for LSD. US 560 LSD were 2.47, but Euro cars usually had 2.24 i think.

I know the W116 6.9 came with a 2:65 LSD, that should fit perfectly into a Gen i car.
The Gen II differential has different housing and mounts, but the innards between Gen1 and 2 are the same and can be swapped.

David, what was the rear end on your Gen II Japan 560SEC ?

Also, from looking at quite a few M117 engines with heads off, it looks like the top of pistons indent for the 2 valves are a single rectangle.
I have looked at HV high compression engines where pistons had 2 round indents over the valves

The 10:1 560 motors (822 code) used 16/17 cams, the later 1988 and up uses 24/25, identical profiles, more aggressive at higher RPM than stock standard 180kW model.

Also, these cars came w/ 2.65 LSD's, such as was on my 90 Japanese home market car.

Hey Horst, long time no chat!
Euro 560's came with 2.65 LSD's (unless it has ASR which is an open differential). US 560's came with 2.47 LSD's (again, if it had ASR, it was open)
Gen I Euro's commonly had 2.24's, some LSD, some not... some also had different ratios depending on option and country of origin.
US 6.9's and Euro 6.9's had different ratios, but would only fit Gen I 126's.... they will not fit a 560.
