thats awesome thanks heaps, seems really easy. Hows your r31 go?? The series 3 r31s have a better AFM ive been told aswell

i recently got a new rb30 in my car and the mechanic that did it had about 18 engines at the workshop he told me that the series 3 RB30 were th best due to the stronger head as mentioned above and he said that holden had slightly detuned their RB30 as per some agreement with nissan this maybe the reason for the 3kw difference

i think i've worked out the way nissan rated the engines higher. nissan info and vehicle handbooks list timing as 15 + or - 2deg on 92min ron fuel. holden info and vehicle handbooks list timing as strictly 15deg on 91min ron fuel. i think nissan took advantage of slightly higher octane fuel and advanced the timing that extra 2 degrees and that allowed it to make a smigen more power, haha, they done what they could for marketing purposes.

what about the nissan rocker cover bro thats gotta be the reason Some original photos have not been recovered yet.
