.. is beginning to look like a tall order!
I currently have a 3.545 R200 diff in my '76 4 speed 280z, according to this:
According to this thread on zcar.com, the only cars that come with a long-nose R200 are the following Z cars (nothing from any other marques?) - and only 4 of these came with a 3.9 ratio:
75-76 280Z, 3.545
77-78 280Z, MT 3.545
79 280ZX MT,4 Spd,4 Seater 3.364
79 280ZX MT,5 Spd,4 Seater 3.7
79 280ZX-GL 3.7
80 280ZX MT,4 Seater 3.9
80 280ZX-GL 3.9
81-83 280ZX Turbo - all 3.545
81-83 280ZX MT 3.9
84-86 300ZX MT and A/T 3.7
84-86 300ZX Turbo MT and A/T 3.54
87-89 300ZX MT and A/T 3.9
87-89 300ZX Turbo MT and A/T 3.7 CLSD
Looking at the S130 280zxs.. I can't find any info on whether the ones listed above were sold with a 3.9 in Europe, or whether that's just USDM info above. Anyone know? According to this thread on Hybridz all '81-83 non-turbo ZX's had a 3.90 - but does that apply to European cars as well as US?
Looking at the Z31 300sxs.. according to this: http://www.xenonzcar.com/z31/differentialinfo.html only the US 87-89 non-turbo had a 3.9, - so none of the European cars would have it, which surely makes that very improbable to source here?
How often do these diffs become available in the UK?
I'm tempted to just go with a 3.7 as they seem fairly plentiful in the UK, but then I'm thinking will going from 3.54 to 3.7 even be that noticeable?
Thanks for any insight.
George.
