Found a company that prints workshop manuals that have been converted to english, here is the link http://www.jpnz.co.nz
If you go to this page http://www.jpnz.co.nz/afawcs0131170/CATID=...1/products.html you will find the nissan manuals.
Here is the catch, there is one for engine alone for $190NZ but the one under that will be one for the rest of the car and maybe engine as well (waiting on a reply to my email to confirm) but they need 150 requests before they print it, any one that has done work on there cars and have not been able to find any info on what they are doing will know how handy these things are, so, your challenge, if you choose to accept it, is to put in a request for this manual, costs you nothing to request it and once there are 150 requests you can decide then if you want to buy it or not, with all the 33 owners on here would should have enough requests in a couple of weeks.
