Im waiting on the new valve springs to get here so we can replace them but still been thinking about this issue and reading a million threads on here, only similar problem i can find is people fitting RB26 cams to RB20's and having problems.
I've got the old cams and new cams sitting next to each other here and they definetely look the same just obviously the lobes are slightly different, it just doesn't make sense what the hell is going on. Fair enough i could understand if the car lost some top end power due to some problem, but for it to lose power all throughout the rev range and not like any advances timing just doesnt make sense. I keep thinking the cams aren't ment to be set at TDC on the standard cam gears but everyone else has done it like this.
I just hope some one will read this and go "your problem is .........." and just solve this drama lol. F***ing cars, why couldnt i have picked some other hobby.
