[PJF]

Hi all

Does anyone know wether the RB25 engines have problems with the oil pumps and or oil pump drive. I've read that the rb26 engines can have problems in that area.

Thanks for any info

From what i know they fixed the R33 and R34 RB26det, although the rest suffer the fate of oil pump drive problems.

Solution is fitting a new crank collar.

Early R32 GTRs had a small oil drive on the crank and needed crank collars, late R32 GTR's (94s did, not sure when 93's started getting it) got the same crank as the R33 GTR (with the bigger oil drive and no longer needed collars)

Anyone need a crank collar just let me know.
