I am sure it is stated somwhere on this site.

I have spent a few nights now using the search function, have found a couple of people claiming rb26 and rb20 springs fit and give me a higher spring seating pressure - but don't know about binding when fully open?.

What i want is confirmation of somone using these before i go and order these from an interstate company.

The interstate company cannot match up with my rb25de springs to forefull my requirments.

Any help appreciated.

hey mate.

i have the same r32 rb25de head on my fully built rb25/30 motor..

im running gtr valve springs with a ported head and standard valves...

altho not yet running in my car..

dahtone racing is a member who i brought the head from..

i know he was running it and it was going fine..

good luck mate..

id say rb26 springs would be the go for you

I'm running an R32 RB25DE head on my 25/30 and running stock valve springs, it was previously in a car with a pair of 2540's bolted on and making 365rwkw @ 21psi with no valve float issues.. so I don't expect any issues with my GT35R either.

I have ordered a set of valve springs from performance springs to suit rb26, there springs are rated 45% higher seat pressures than standard so this will be ample. They cost $279.50 delivered, which i think is very reasonable.

As long as they don't coil bind they should be good.
