I was doing a bit of reading Alan- the cars in 75 and 76 are regularly described as a 240 then a 260 a year later . Then I found this :
“Interestingly, for both 1975 and 1976 entrants there is some confusion over whether the cars were the 240Z or 260Z model.
The 240Z was the initial version with a 2.4 litre engine (a strong and unburstable straight six with roots back to a Mercedes unit), with the 260Z following it with an enlarged 2.6 litre unit, introduced to combat the ever tightening American anti-smog laws.
Some say that the 1975 car was a 260Z with a replacement 240Z shell, however both the listed engine size and outward appearance would suggest it was a 240Z through and through.
The UK Z Club have suggested the car was actually a 260Z with a Z432 body shell on it (this was the reference given to the Japanese market 240Z), but the jury is still out! “
Don’t want to be a pest - but I’d love to understand the facts . Not sure how accurate that article is.

The car was based on a Japanese market Fairlady 240Z ('HS30' prefixed) and was much modified by the Nissan Works team for entry in the Kyalami 9hrs race in 1973.
Nissan built two cars for the race. They featured all the current Group 4 & 5 bodywork (Grande Nose and extra wide overfenders) and were running L24-based engines (Nissan called it an 'LR24') taken up to the allowable oversize in each class and with the 'Safari' FIA cylinder head, running on the factory ECGI electronic fuel injection and with a trick oil replenishment system for endurance racing (making pit stops faster). They were very interesting cars.
They did very well in the Kyalami race (coming an amazing 4th overall) and Nissan left one of the cars in SA for local drivers Chatz and Mortimer to use in the remaining races of the Springbok Series. Not long into the series the Arab Israeli War and the OPEC oil embargo caused the oil crisis and the remaining Springbok Series races were cancelled.
Hans Schuller (well connected German, winning navigator of the '70 and '71 EA Safari Rallies with Edgar Herrmann) brokered the sale of the car to Haller, and the car was brought to France. Haller used it in a couple of hillclimbs and short circuit races before entering it in the 1975 Le Mans 24hrs (co-driven by Schuller and Benoit Maechler) and somewhat miraculously making it into the race by default after some other entries were withdrawn (politics).
In order to give the car a legal identity for import (Nissan hadn't necessarily intended for it to change hands... ahem) Schuller furnished the car with the identity of an ex-Works RLS30 rally car that he owned. The rear number plate was also affixed to the car, causing much confusion years later when people thought the car actually *was* a ex-Works rally car, when in fact it was an ex-Works circuit car.
They finished 26th overall, hence getting an entry to the '76 race. It was the same car both years. The '240Z' vs '260Z' thing is just the usual problem of people looking at engine capacity rather than the actual model of car.
Don't know where that
"....The UK Z Club have suggested the car was actually a 260Z with a Z432 body shell on it (this was the reference given to the Japanese market 240Z), but the jury is still out!... “ comes from. The car was actually a Works-built HS30 Fairlady 240ZR.
A fascinating and quite deep story, tinged with sadness.
