I had some time to kill today so I got to look at the Larrouse 911R car.
What is to the right of the upper arrow?
I love the fuel line connection that feeds the Weber rubber line. I've never seen this type of line before.

Been around a long time....some 356 models had similar fuel lines. Dunno about the upper thing.

That's the factory fuel line, no different than the ones on other 911s of the period. Porsche was reproducing this part a few years ago, but they are now NLA again.
Those things above are ceramic ballast resistors for the ignitions. The black squares with fins on them are the electronic ignition, the resistors work in connection with the electronic ignition to limit coil current so the coil doesn't burn up. The reason there are two is for the top and bottom plugs.

Not sure this is a real 911R, but the story said yes.
Here is a photo, don't see the same white items in your photo.

The black boxes are the transistor ignition boxes, used with the white resistors and transistor coils. I don't believe there was any other factory street car use of the system. The blue car may be an R but not much left of any original systems I see. Gordon
Thanks to everyone.
My '58 Corvette has a ceramic ballast resistor. The Porsche ones are about 3 times the size of the one on my Corvette.

This is a Carrera 6 engine. It was a 1991-cc air-cooled flat-6 that was basically a racing version of the engine used in the production 911 with some changes, like exotic metals in the connecting rods and crankcase. Horsepower as 210 at 8,000 rpm, torque rated at 146 lb-ft at 6,000 rpm. The 5-speed gearbox was also 911 production based. It was also the exact same engine used in the 911R - just pointing in a different direction.

The crankcase in the R is sand cast ALU with special features vs sand cast Mag in the 906. Extra weight saving items were used in the 906 that were not used in the R's, like the alternator with massive hole drilling's in the case. G
You would need to find period photos to confirm that those ballast resistors were correct for that car.
Here are the ballast resistors pictured in the factory manual for a '67 910, which were the same type still being used in my '72 BMW CS...
