1978 Datsun 280Z

Sean, I was comparing US 240 which got progressively slower btw with 280 and you throw in Euro spec 240, poetic licence. Rear diff on 280 is 3.55 closer to 3.90 of Euro spec and better than 3.345 from memory on US240.

Ah…but you never mentioned USA 240Zs in your text and you are selling the 280Z in Europe and comparing it therefore to contemporay cars here for sale or otherwise….don’t bend the goalposts or whatever the expression is  !

The other point I would make about 280Z is that the later cars of 77 and 78 have more power than the earlier 75 and 76 cars ( 170bhp v 150bhp ) and performance much closer to the early 240Z.
The reason the L28E engine did not improve drastically over the L26 was compression ratio down to 8.3 from 8.8 so the engine could use lower octane unleaded fuel plus all the emission eqt, cat converter etc.

Road tests of the day put the standing quarter mile at about 17 secs for 240Z and 280Z in its first incarnation with 150bhp. 0-60 the 240Z quicker car by at least a second but 280Z with 170bhp got much closer.

My reading says that the (5spd) 240Z was around 16 sec for the ¼ mile, only equalled by the 2x seater 260Z (just so Status can go all gooey) and that the best a 280Z of any year could manage was a second slower.

Both 150 and 170 ratings are gross SAE as far as I am aware ( stand to be corrected ) and corresponds with what I have read and seen on chassis plates of 77 and 78 cars which gained the extra power from engine mods and improved emission compliance.
Please show me a 1975/6 chassis plate and the SAE stated power.

Should have said 280Z shared L28E of course and yes a bit sloppy for some with ZX ;)

Except that the last 280ZX versions were beefed up and along with rack and pinion steering were very good cars on the road, they only lacked the turbo (only sold over here in Germany in 1983 I believe ?) to have ‘blown’ away the competition !
 
without not wanting to talk about speeds 240/260/280's....

Could it be that the 240z just feels more like a 'classic' given its less refined interior, lower weight etc.

Its not just about the numbers is it, its how they feel.

They are all proper classics with unassisted steering and basic controls but the 240Z has a lighter feel and definitely most raw and unrefined of all.

Except mine with electronic ignition, vented fronts and disc rears, PAS, Efi, LSD, DIY, don't know Y and the rest.

Who cares about top speed, we could be here for ever. Mine will waft at 50mph everywhere, looking the mutts.

Zs don't really waft but I hope you get my drift (it won't drift, either).

I allways sed the 240 is raw and not as refined as the 260 but great cars to drive,and if I had a choice now ,knowing wot I know now I would go for a 280 or just put the running gear in a 260 ,where do you stop ? You dont

In that case you bought the wrong car dear boy :D

You need a Jag or a Roller for wafting or perhaps a ZX ( S130 Mr.T ;) ) excluding the factory turbo version that is of course :D

Yes, waft was the wrong choice of word! What I mean was for me, the Z experience isn't defined by what speed it can go or how wide the wheels are or how low it is or how much can I not see in those daft wing mirrors eight foot away ...

Yes, we are just having light hearted banter ;)
Livens up a dull Winter's evening for some.

I love all the S30/S130 models and who cares if one model is a nano second quicker to 60 or has 1mph better top speed. Most cars have been modified anyway, some engines more worn than others etc etc and the figures we quote from road tests were with brand new cars back in the day. If we were all driving around on empty racetracks may matter slightly but our roads are so congested we would be happy to waft around at 50mph more often than not.

This must now be the longest and most off topic for sale thread ever.
Should have known to stick to the discussion section :D

Right, off to wind Riddler up about his wafting Rover, haven't you found a Rover forum to join yet Rob ? Told you there would be withdrawal symptoms, you can't keep away :lol:

Rob ,stick sum 10% uprated springs and a set of Kong shocks and you will have a totally different car that handles great

Omg, KONG shocks ? Do those go with King springs then ?

My car will be powerful but I'll have as much satisfaction and enjoyment at 30mph as I will a 'little' bit higher....it'll just all be in top gear:D !

Actually quite like the wafty/rolley ride. All part of the car. It's incredibly smooth, takes the bumps like no other car I have driven, and is surprisingly powerful, particularly now I have had that lovely V8 engine completely rebuilt.
Following the rebuild have now taken it to a tuning specialist, and I thought you might like to see the figures it produced on the rolling road!
At 4,397 rpm it delivered 151.8 bhp at the engine and at 4,365 rpm it delivered 131.5 bhp at the wheels.
Pretty happy with that!
Attached are a couple of pictures taken during the rebuild and the rolling road report/performance graph for those who are interested.
