What Are These Valve Springs From?

[CruiseLiner]

hey guys i got some valve springs with blue on the bottom of them and the gtr stock ones i got have white bottoms same as it says in the workshop manual. now what type are these blue ones? are they even from an rb26? i measured the stock gtr ones compared to the blue ones.

the blue one have a coil metal thickness of 4.9mm

the white ones from stock gtr are 4.7mm

the gtr stock ones are wayyy softer to press down and blue ones are really strong in comparision.

any ideas how i can find out? anyone seen blue ones before?

do the stock inlet and exhuast springs look the same? and do the retainers on the inlet or the exhuast use a washer to compensate for the length on one of the two sides?

the pic on the right is a stock gtr one on the left and blue one on the right

cheers

Umm

i have seen the Blue springs in the TOMMIE SOLID LIFTER TYPE B kit.Designed for the Pro Cams

The yellow spring is Stock RB25

i think white is STOCK RB26

Unsure whats going on but maybe a mix and max

With the Blue springs on the rb25 head there is 12 special Retainers which needa be used

Standard GTR Valves and Springs are Equal Sized in length,The Diameters are different.They use a Washer at the bottom of the Valve Spring to locate it and stop it from Biteing into the head

Standard RB25 Valves are Same length and different Diameters.The Valve Springs howeva are Shorter on one side.They also run a washer
