Decals for a 2.0 Options

[thomasotten]

For a 73 2.0, does someone know what the correct sticker is for the right front wheel arch? This one says it is for a 1.7 L.

Also, are there any decals in the engine compartment for a 73 2.0?

Many thanks

Can anyone with a factory 73 2.0 please confirm that the middle decal shown, with 98 ROZ is the correct one for a 73 2.0?

no it is not for a 73 2.0
you want the 91 RON sticker if the car is a 73 USA 2.0

here is how they go from info i have collected along the way doing L jet research.
if you look closely jeff b has question marks on the grey 95 and 98 RON stickers - for a reason i'm guessing which would be that he had not seen them on a car and was unsure of their origin and spec - they are rest of world stickers but not USA stickers.
USA was progressively shifting to unleaded fuel in the years 73/74 and the cars had to be able to run on the unleaded which at that time was quite a low octane. 91 RON and that was it, unlike today when we have higher octane formulations of unleaded.




the way it went in 73 was -
USA (49 states) 1.7 was allowed to run on leaded high octane (98 RON sticker at top).
CALIF 1,7 had to be able to run on 91 RON (mandatory) - probably had grey 91 RON but i have never seen an original example.
USA + CALIF 2.0 ran on 91 RON. this was mandatory for CALIF but not yet required in 49 states. Porsche did it anyway for 49 states presumably because the 2.O was freshly developed that year and they knew it had to run on 91 USA wide the next year in 74.
so all the 2.0s had the grey 91 RON sticker.

in 74 all states of USA required the car to be able to run on 91.

in 75 all CALIF cars had the restrictor that meant it could only run on 91 (Cats were fitted). rest of USA remained had to be able to run on 91 and did not have the restrictor i believe.
