Rb26Dett Valve Springs In A Rb25 Head

[Guilt-Toy]

I scored a set of valve springs, but they are for RB26DETT.

Anyone used the valve springs from RB26 into a hydro RB25DET s1 head?

Its the HKS Step 2 ones.

RB26DETT 22001-AN001 For STEP2 BNR32, BCNR33, BNR34.

I have got Tomei 270 8.8mm lift cams, in my rb25/30.

really would like to use these if i can.

any ideas?

cheers

From memory of the 25 valve springs 1 is shorter and the other is the same as a standard 26

You will have to check the installed heights and compare to make sure they have enough lift

I cannot really do that, I don't want to open it unless they are going to go inside, not strip down and put it all back together again and back to where I started.

I can ask paul tomorrow. Send me a msg to remind me. Surely he will know

VVt RB25s have a long and a short spring sorry.

So.. thanks for reminding me to call Paul, Mr Red R Racing comes through and answers a private number from overseas for once! was good to catch up...

So he mentioned that because these cams are not so big, it should be okay with stock springs, and that there will be no issues with the springs, but then he started being a detective and found some flaws with my setup and put me in the right direction!

car dropped a cyl once or twice, and once the engine even shut down... he said that I need to change the oil restrictor situation in the head, at the moment its setup as how sydneykid suggested in his thread but now for me I need to go back to twin 1.2mm feeds to give my lifters some more oil to stop them from bleeding and playing up.

also pointed out that the thick oil i am using aint going to help my situation either, i just switched to the lemans, so looks like its back to competition for me! (Motul)

Also, there is NO chance RB26DET springs will work in a Hydro rb25 vct liftered head. (for the searchers)

going to rip the head off and get this sorted asap!

cheers for all the input guys, im sorted

Go big valves and port work while you are there

WHY DID YOU HAVE TO SUGGEST THAT?

[zebra]

because I know you love horsepower

[Guilt-Toy]
