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

      Does 98ron contain ethanol?

      By GTSBoy · Posted

      Actually, ethanol has probably never been cheaper, on a tax free basis, than petrol. With fuel excise being what it is, and only being levied on the hydocarbon component, not the ethanol component, and ethanol for non-drinking purposes not being subject to liquor excise - E85 was cheaper, but not because the combustible liquid itself was particularly cheaper.

      Will I Need A Retune After Cahanging My Catalytic Converter ?

      By Murray_Calavera · Posted

      Maybe? If changing the cat to a higher flowing cat, caused the turbo to spool more quickly, and those areas of the map had not been tuned for the boost level it is now seeing, then yes you would need a re-tune. How dangerous it is running without the updated tune would depend on how far out the tune is with the now higher boost levels, how the engine protection has been setup, is the ECU compensating with a wideband sensor, is the boost control closed loop blah blah million other things... But yeah having said that, I wouldn't be surprised if changing out the cat for a high flow, in say a full 3" exhaust, made no noticeable difference at all.

      Need AC Compressor for R32

      By silviaz · Posted

      Ah yep. I asked a auto electrician about getting a cheap rebuilt alternator vs a new one. He also said he used to it back in the day but it ended up costing similar to what a new one would and recommended getting a new one,.

      By silviaz · Posted

      Ah, to clarify if the car has already been tuned and has been modified and you want to go from a oem cat to a 100 cell or decat or vice versa.Are you saying that the car doesn't need to be tuned after a cat change if it's already been tuned?

      High temp brake fluid?

      By Komdotkom · Posted

      This has been covered a bazillion times but google wet boiling point vs dry. Motul is only good when it's fresh, once it absorbs moisture it gets pretty average very quickly. So as above, make sure you change it if you're going racing. I run the Endless brake fluid in mind, but only because a mate is a distributor and it's cheap. It's not quite as good as SRF but I'm running 380mm rotors on a Skyline so it's not like they get hot.
