having had an email off jeff as what to do i set timing gun and it was 40deg btdc as i turned cas as it was fully advanced to bring it to 15deg btdc ,took it for a spin and misses and not much power the cas is almost fully retarded now.

set it halfway showing 20deg btdc now still misses alittle but no pinking haha i dont now maybe the bloke who done belt fitted it wrong

Yes, the belt could be fitted wrong. I believe this has been done many a time on these cars.

Just another thing, is your car a manual or auto or importantly an auto converted to manual because if the latter and the neutral switch is not connected the car ecu will make the timing 25btdc. Or indeed if you have a manual and the neutral switch has gone faulty.

My car is auto converted to manual, my neutral switch is not connected up so my car always reads 25btdc when hot and idling even though belt is fitted correctly.

its manual but not sure if it used to have auto box im trying to get hold of previous owner,didnt even know had neutral switch where is it and how much are they?

ok ive read about the neutral switch,i had belt changed cas was at maximum advance and pinking like hell under load,so even if switch gone or 44pin not earthed it should read 25 deg btdc on idle when warm,it was 40deg btdc so in theory if i set to 25deg btdc and runs shit its the belt thats been fitted wrong?

Would seem like you on the right track there, will be looking like bad belt timing as you say if the car runs poor with 25 deg setting with an open or missing neutral switch.

No mate as far as I am aware my old Z was never a Auto allways been a manual since the day I owned it.

I fitted the belt my elf using info off here and a timing gun.

Oh after trauling through all your posts you have had a new belt fitted by a garage who has got it wrong. lol For a second I thought it was the belt I fitted when first bought.

No wasnt you mate rip off garage down here,they not used to working on these types of cars cheers ,ive emailed you pics etc
