The one thing you need to know is the Safari is a totally different Kettle of fish (Rally
).
a 240 IS a 240 if its what me and you know is a 240. What came off the production line as a 240z - a 240Z is not a 240z when you stick a 3.1 litre (that would be a 310Z) engine in it or v8 in it ..... I am going to wish i never said that!!!
Did you know that when Rob Collinge won the rally in 2003, alot of the top contenders put in a grievance? The Porches and Fords could not take the fact that a 2.4z kicked arse of the much more nimble fords and porches? Rob had to strip the engine to prove that the car was legitimate.
In 2005 he used the same shell and put in a 260 engine and entered it as a 260z.
Regulations say "Engine overbore beyond 60 thousandths of an inch over the manufacturers specification is not allowed"
If you entered the cars "correctly" - you would need an official that is so clued up with everything and every nut and bolt on the cars not just for Datsuns, but fords, Porches and the numerous other makes and models. Technically not possible and never going to be cost effective!!!
The regulations of the event open alot of things to "interpretation". For example Suspension, "Type and general layout must be original shape, design ....... then goes on to say .... additional shock absorbers are permitted" .... so the big boys us massive 55mm - 70mm fully adjustable, external cannister set-up!!!
Proflex, Reiger and the like .....
Imtiaz Dewji entered the Datsun 240z in 2003 (z farm prepared) that was a correctly entered car.
.... To appreciate what I am saying you need to see the Rally and the cars entered to compete in it.
