Hi guys I know I'm a little of the subject but I thought I would try my luck.I have just purchased a RB25DE motor so I can use the head for a rb30 transplant.Now my question is regarding whether it's a series 2 oe 1 as I want to buy some new cams and have to let them know,I was told it was series2 when I bought it and it has series 2 coil packs on it and harness. But a friend of mine said he believes by looking at the CAS that it has a series one CAS,he explained that series one are silver and series 2 are black is this correct or is he dreaming and is there any other way of finding out.I know it's off the subject but any help before I waste my money on the wrong cams would be greatly appreciated.PS engine number if it helps RB25 115051A
Thanx
