RB25 Solid Lifter Conversion

[Chaos the Xile]

I'm currently rebuilding my RB25 head, wanting to use solid lifters instead of hydrolic since i'll be running Tomei Procams. Instead of buying a set of Tomei solid lifters could the RB26 stock solid lifters be used without any modification to the head?

We wish it was that simple, unfortunately it would involve a lot more since the Rb26 valves are different lengths compared to rb25.

i think that the 25 lifters are a bit smaller then the 26

damn! wel i guess its the tomei lifters then let me know if you find em cheaper than $490

[eh?]

The diameter is the same per the fsm. Custom shims maybe needed? Don't know, you can try buying a RB26 lifter or two and check out the clearances yourself. Either way you would need new shims. I'd rather buy a whole RB26 head and be done with it.

well eh? if you find me a complete rb26 head i'll buy it... but a shop by my house has a couple of rb26's in stock maybe i'll stop by and see if we can frankenstein some stuff see what works... maybe it'll lead to a pretty interesting walk thru, who knows.

I can find n/a RB20 and 25 neo's over here with out to much trouble. Would they have solid lifters you could stick into a turbo 25 head?
