Thanx Squeeze, Side question, with the plugs out and most of them WHITE from running lean, What should I go with was looking for a heat range colder? But what brand? HKS, NGK? I have always used NGK's but also was in DSM's, This is my first Nissan build?

HKS 50003-M40HL M-Series Super Fire Racing Spark Plug Nissan Skyline GT-R

HKS 50003-M45HL M-Series Super Fire Racing Spark Plug Nissan 370Z

You can use either one of these.

We spent a lot of time finding a good plug. Its a very skinny plug. We actually found the GT-R plugs to work well in the 370z. The gap out of the box on those was .030". That's a DILKAR8A8 plug. You used to be able to only get them at the dealership but my main NGK supplier should be able to get them for me now so you shouldn't have too much issue tracking them down.
