Timing diagram i need the timing diagram for a 1995 j30 infinti iam putting a new timing belt on the car

You have Nissan's VG30DE engine in your car. If you go to www.ttzd.com (Twin Turbo Z's of Dallas), you'll find Tech articles for the 300ZX (the non-turbo version is the same engine that you have). One of the articles is the full timing belt service job. I believe it was done on a twin turbo, but for purposes of the timing system, the turbo and non-turbo are the same. It'll give you all the info, pictures, tool lists, and step by step instructions that you could want or need.
