RB30S cam

[JeffGH]

I have an RB30E in a Holden one tonner (R31 Skyline version). Lovely motor but needs lots of revs to pull a loaded vehicle with a car trailer -one tonne diff. is actually higher ratio than a Skyline.

I notice the GQ RB30S develops maximum torque (224Nm) at 3000 rpm as opposed to my motor specified as 252Nm at 3600 rpm.

My cam is well worn and need replacing. I am wondering if a GQ cam might give me some more low down torque. Does anyone have a factory manual with cam duration and lift figures?
I have Skyline and VL Commodore manuals so know cam specs for that version of the motor.

Also, comments on end result of fitting EFI to GQ motor would be appreciated. I might end up with, effectively, such a motor.

Thanks,
Jeff

G'day, JeffGH. Alitis007 is the man to ask about RB30 engines. And also use the search function, top right hand corner of the screen. There is plenty of info on efi engine conversions
