Hi All, I have just joined the Z club as I have purchased my first Z. It is a 1975 JDM Fairlady Z 2/2 in blue. Very little history before it was imported in 2017 and then treated to a serious restoration and new paint etc.
Its actually in good nick and they did a good job overall including the interior although there is some confusion in the auction houses and dealers as to what it capacity actually is. It is a GS30 and has the L20 (A) engine block, matching numbers on the car also but it comes with a claim it has been "upgraded" to 2.4 litres. I am still investigating this and will get back when I know but it would have been possibly rebored and a preferred piston size would have to be used but I also understand to achieve a true 2.4 litre status, it would also need a new crank to change the stroke.... and bigger carbs possibly.
I can measure the stroke through the spark plug hole I think but it will be difficult to accurately measure the bore without taking off the head (that can wait until the HG need changing one day). I have thought about using oil to fill the piston on the BDC position and then slowly turning by hand, seeing how much is displaced to calculate 1/6th of the capacity. Let me know if you can think of a better way to measure the capacity without causing issues.
It doesn't seem to burn any oil and I will be doing a compression check soon to investigate it state after the claimed 47,000 miles (all in KM still...)
Thanks and looking forward to an interesting club.
