Thanks for everyone's help   Managed to find a local garage that have done a lot of work on 350z's and at a reasonable rate. They picked the car up yesterday morning on a trailor and engine was out yesterday :smile:   
I have to give a big thanks to zmanalex for his patience and excellent service as the parts turned up this morning so i took them straight to the garage who are hoping to fit the parts tomorrow and then put the engine back in. So with a bit of luck the car will be back with me by the end of the week  
  
All in all its been an eventful first fortnight of z ownership
