  1. Sorry, I've never seem that system 🙂 what happens if you unplug that switch?
  2. can you describe what you've got in a bit more detail @jas. you've mentioned EGR and water temp switch, neither of which I'd expect on a 72 carb car.
  3. Does your thermostat housing not have a blanked hole next to the standard sensor housing? mine does, its a standard size, m12 maybe.
  4. The Zclub in the UK has a thread on seat upgrades at the mo with some interesting options. https://zclub.net/community/index.php?threads/seats-again.27924/
  5. they don't have struts, but they do have strut inserts : https://www.thezstore.com/page/TZS/CTGY/classic20b04
  6. must be an electrical problem. Maybe your alternator is over or under charging?
  7. If it was smokey, make sure you change the valve stem seals. Maybe even check the guides aren't too worn. It won't be the compression rings.
  8. not only will it take a lot of filing, I imagine it'll be under quite a bit of stress, being that compressed. And if the bore isn't round, it'll still not seal, as @zedhead pointed out.
  9. I don't think there's a down side to a big cam in a Z. Mine is ~15mm lift and it goes like a normal engine below 4k rpm and a not so normal engine above. No 'driveability' problems anywhere. You wont get the full benefit without exhaust, carb, head etc improvements but it won't hurt.
  10. is your current ring end gap 0.049"? thats 1.2mm, which is very big. my recollection of the spec is around 0.3 to 0.4mm for the top ring.
  11. I don't think any original standard Nissan pistons have cut outs like that. on the compression rod, I have these, which are cheap and effective. https://www.thezstore.com/page/TZS/PROD/23-4190 I had poly bushes both sides before I fitted them, and I had a lot more roll after I fitted them which I think shows how much load they were taking.
  12. I've got an e88 skimmed to 36cc chambers on a "big bore l26" and 10.5:1 CR I built recently. There's no problem with chain tension or cam timing. It hasn't run yet but it won't ping on decent fuel I'm sure.
