Chasing some info on RB26 valves, I'm in the process of a solid rebuild after lunching a ceramic turbo. Forged pistons, bearings etc, bottom end is all together.

After a quick look at the head though, the valves have been damaged.

Now, the problem, I've lurked around the internets for hours now, and searched these forums from top to bottom, including all the sponsors, nobody seems to sell valves.

I found one standard set, second hand...

What kind of valves have people used in their rebuilds, and where did you find em?

naprec valves are good and cheap. I don't know who sells them in aus, I bought mine in japan, but I'm sure you can get them here too.

ive heard that the naprec valves run a smaller than standard size stem which could cause possible reliability problems in the long term with big revs..

i assume you've got the 1.5mm oversize..

so how are yours holding together and how long have they been in the car?

Another group buy coming along Andrew? (id be in :P )

F%#$K no! never getting involved in one of them again!!

i spoke to my engine builder today and it looks like i'm going to run with standard valves. tho i may still do springs and retainers.

anyone ever use super tech?

i've just ordered the full supertech catalogue (dual springs & ti retainers, guides & OS valves) from the states for a mates motor i'm building, should arrive in the next few days

prices i got were:

valves full set (1mm SS inlet, 1mm Inconel exhaust) - US$499/set

dual springs & ti retainers - US$459/set

manganese bronze guides - US$120/set

total including shipping in aussie $$'s was $1466.12

make sure the guy installing the oversize valves inserts a new valve seat as the std wont cope with the oversize valve

    • Hi...so a "development" here aswell The swap is "done" and car went "test drive" BUT it seems the clutch(maybe gearbox?) is a little bit sad? I bought this clutch kit https://justjap.com/products/xtreme-heavy-duty-organic-clutch-flywheel-kit-nissan-skyline-r31-r32-r33-push-type "Problem" is that the first gear is hard to put into and it seems that the clutch is not disengaged. It was not the problem with the old clutch...(or like sometime the first gear would not get as easy specialy when the fluid was cold) So? Can it be like...bad "install" or is the clutch wrong ((it should not have been) i done research to get the right one) Or is this "normal" with new clutch and needs to be break in? 
    • @Duncan I can try  and thanks i did not thought about VIN and part numbers for 33/34. @GTSBoy yeah it looks like iam gonna do that  
    • Forgot to include this but this is the mid section of my steering rack that looks like it has a thread/can be turned with that notch mentioned in the post:
    • Hey everyone, Wanted to pick some brains about this issue I'm having with rebuilding my 33 rack (PN is 49001-19U05). All of the tutorials/videos I've seen online are either R34 or S Chassis racks which seem to be pretty straightforward to disassemble but this process doesnt carry over to my rack. Few of the key differences that I've noted The pinion shaft on the other racks bolt on with 3 torx bolts: Whereas my rack bolts on with 2 allen head bolts: These changes are pretty inconsequential but the main difference is how you pull the actual rack out of the housing. The other skyline/s chassis racks can be taken out by tapping the rack out of the body with a socket and it just slides right out. I'm unable to do that with my rack because there's a hard stop at the end that doesn't let the seal/shaft be tapped out. Can also see a difference in the other end of the rack where mine has a notch that looks like you're able to use a big wrench to unthread 2 halves of the rack whereas the other racks are just kinda set in with a punch. My rack: Other racks: TLDR; Wanted to know if anyone has rebuilt this specific model of steering rack for the R33 and if there were any steps to getting it done easier or if I should just give this to a professional to get done. Sorry if this post is a bit messy, first one I've done.
    • I would just put EBC back on the "I would not use their stuff" pile and move on.
