Help! I had my track car sitting around for a while without being started very often now whenever i start it, it cranks for abit and then suddenly makes a clunking noise and nothing happens until i turn the ignition off and back on. I've replaced the battery, starter motor and the alternator and still has the same issue. I've noticed if you don't turn the key to the fully on position just turn it enough until it cranks it eventually starts. Any help would be great. cheers

Poor earth? Bad connection somewhere. Generally resistance increases with heat so this would explain why it is worse when its hot

Long shot but worth a look

I was going to say maybe a dodgy ignition barrel but it sounds to inconsistent for that

Ill have a look at my wiring diagram when i get near a computer to see what it could be

Yep, as above. Had a similar issue a while back. Check the +ve on the starter, then check the earths from the motor to the chassis and starter to the motor. Grease and crap may get in between the contacts so give them a sand and tighten them back up.

      R32 gtst speedo out by 10kph

      Nope. The seal is in the drive. A new cable would just fill up and continue to convey oil to the speedo head. To check if this is what is happening, take the cluster out, dismantle the speedo and have a look. You probably don't even have to dismantle it. If there is oil coming up the cable, the drive into the speedo will be grossly greasy. I had to manually (and delicately) clean the gunk out of my speedo.

      Thanks for the quick response mate, and I agree Nismo 555s, Z32 and high flow 2871 in OP6 housing (run by PowerFC) would all be "period correct" and should be a simple, reliable and reasonably quick track car.

      It is normal for a speedo to read 0-10% high (unfortunately), intended by manufacturers and ADRs (although not in this case) to ensure your speedo does not read low if your tyres are worn. Speaking of which, what size tyres do you have on the rear, and what does they tyre placard say you should have? you can use this https://tiresize.com/calculator/ to determine what % difference that is causing Personally, when I buy tyres for a car I buy a size that will bring the speedo back to being more accurate; it if it reads 5% high I buy tyres that are 5% larger diameter. If you had an electronic speed sender like R33 onwards, the other option is to add a speedo adjuster but that won't work in R32. Finally, you  might be able to find a different sized gear for the speedo sender but that will be limited to what already exists (and I don't know what sizes do)

      OK...so dumb question to check....do the hi beams actually come on when the push the stalk to engage them (keeping in mind your headlight switch must be at ON as well)
