Wtb: R34 Gtt Rb25 Neo Exhaust Lifters

[TheSn4k3]

I recently bought a head from a guy here in the states and turns out the head had a ton of problems. After refreshing the entire head the only thing left to replace Is the exhaust lifters but I can't find them anywhere for a reasonable price. I really only need oem and I don't mind used as long as they are in decent shape. I live in the USA so must be willing to ship international.

Just for your information. I rebuilt my NEO head just recently I pulled the lifters out (Engine had only done 39,000km) to find the lifters were very badly scratched. Instantly i thought they were damaged.

This is not the case, the exhaust lifters are made out of Aluminium, they wear like that, it is quite normal for them to have 'excessive' scratching and my engine builder told me there was absolutely nothing wrong with them.

Inlet lifters are steel and didn't have a mark on them.

If this is why your wanting to replace the lifters, because they look badly scratched. They are in fact fine.

If they are physically damaged in some other way and you need to find a set, your probably best of going New OEM as you'll have almost no luck finding a set. There is nothing available after market for the NEO either.

That's actually the exact reason. Let me ask you though did yours have Any play to them at all? My intake lifters fit snug but my exhaust are somewhat shaped like an old wooden barrel, best analogy I could think up, and have a very little bit of wiggle to them. It's nothing drastic but it scared me. That mixed with the scratches led me to believe they were the wrong lifters.

Mine had very slight play with the inlet being snug.

So long as they dont have excessive play, bind up or have lots of physical damage they should be ok to use.

Why Nissan used different lifters for the exhaust on the NEO but no other RB is a mystery. But I'm sure there was a good engineering reason for it.

Make sure your valve clearances are set well.

0.31mm +/- .04mm for inlet and 0.5mm +/- .04mm for exhaust from memory.

Shim over bucket valve trains tend to flick out shims with incorrectly set clearances and/or aftermarket cams.

Yea I'm going to work on shimming them today. Sounds like my lifters are fine. I may look in to a valve cap kit but I'm not running higher rpms or crazy numbers so I think I'll be fine as long as I set it up right.

Thanks for the help and the info. You have saved me a ton of money, time and headache
