rb25 valve guides

[jbballa9876]

So i have dissassembled my s2 rb25 head save for the valve guides which the machine shop will remove. My question is what valve guides to use? Tomei is too much and i want to go with supertech. Supertech only has them for rb26 which is the same as sr20 Supertech GDE-NSR6-I Valve Guide Intake S13-S15 SR20DE(T) & RB26 (http://www.frsport.com/Supertech-GDE-NSR6-I-Valve-Guide-Intake-S13-S15-SR20DE-T----RB26_p_15785.html).


I have found another rb26 valve guide from rhdjapan that says it is compatible with rb25. TOMEI Valve Guide - Intake RB Engines (http://www.rhdjapan.com/tomei-valve-guide-intake-rb-engines-21045)

Finally on tomei website they have a different part number for rb25 valve guide set and rb26 valve guide set. http://www.tomei-p.co.jp/inf/pdf/134-AE.pdf


My goal is not to buy tomei and use supertech. I feel like they are the same, but i am not sure. Can anyone help me here?

i found that intake side are the same on rb20, rb25, and rb26 according to tomei website. It appears exhaust side valve guides are different though. If anyone can find out more info or knows anything thank you ahead of time!

Just to add exhaust side valve guides are the same for rb20 and rb25 according to Tomei order infomation page so this is what im looking for but something cheaper than Tomei!

Thank you very much for that info. Tomei has the same part number for the intake valve guides for rb25 and rb26, but this sheet does not include rb26 for intake valve guides. I dont know if rb26 are the same too? (for intake side)
