Ive had a bit of noise my engine (rb25det), and as ive had permanent lifter noise previously, on the offchance that this noise is a badly stuffed lifter, im taking them all out and cleaning them. The specific noise i had ive recorded here

But im not quite sure on a foolproof way of testing which are stuffed, and how to clean them. Ive read the guide to cleaning/testing lifters on a lancer, but they are quite different to the rb25 lifters.

Does anyone have more information on how to test them and/or how to clean them?

Do you how many kms are on the motor? have you left the oil cooler on its mount or put on a relocation kit? the lifters can be checked and re-built by a engine recondition place if they cant they should know of someone because thats were they would be getting there lifters from when they do a motor!

kms are supposedly under 100k but with any import motor theres no way to be sure. engine is stock so no oil cooler/mods. as im not sure where the noise is coming from i dont want to spend 24 x 30-60$ on new lifters when they might not be the cause of the louder noise.

Well from the sound file its the lifters for sure have you done an oil change with fresh oil because it sounds like there not pumping up and been an import it may have been run with low oil and its effected the lifters i would pay to have them tested to see if they pump up and can hold pressure

tool the lifters out a few days ago, been in oil since. today my brother flushed them a bit with petrol, then left them in oil till i got back, and he said he thought 2 of the lifters on the second piston from front (no 2?), both exhaust side, were squashy, and i confirmed that this arvo

so with any luck the engine noise is from those two lifters (and both being rooted is consistant with the noise that seems to be only once per revolution of engine (and therefore cant be lifters on two different cylinders, or different sides of engine (that are equally as stuffed)

anyone know where to buy new lifters? nissan or do they cost too much? (theyre supposed to be 40$?)

find somebody in the FS section selling a halfcut or dismanlting an engine and get a couple of second-hand ones...

      Mistakes were made, my R34 Story

      By Kinkstaah · Posted

      I'm back from the dyno - again! I went looking for someone who knew LS's and had a roller dyno, to see how it shaped up compared to everything else and confirm the powerband really is peaking where Mr Mamo says it should. TLDR: The dyno result I got this time definitely had the shape of how it feels on the road and finally 'makes sense'. Also we had a bit more time to play with timing on the dyno, it turns out the common practice in LS is to lower the timing around peak torque and restore it to max after. So given a car was on the dyno and mostly dialled in already, it was time for tweaking. Luis at APS is definitely knowledgable when it came to this and had overlays ready to go and was happy to share. If you map out your cylinder airmass you start seeing graphs that look a LOT like the engine's torque curve. The good thing also is if you map out your timing curve when you're avoiding knock... this curve very much looks like the inverse of the airmass curve. The result? Well it's another 10.7kw/14hp kw from where I drove it in at. Pretty much everywhere, too. As to how much this car actually makes in Hub Dyno numbers, American Dyno numbers, or Mainline dyno numbers, I say I don't know and it's gone up ~25kw since I started tinkering lol. It IS interesting how the shorter ratio gears I have aren't scaled right on this dyno - 6840RPM is 199KMH, not 175KMH. I have also seen other printouts here with cars with less mods at much higher "kmh" for their RPM due Commodores having 3.45's or longer (!) rear diff ratios maxing out 4th gear which is the 1:1 gear on the T56. Does this matter? No, not really. The real answer is go to the strip and see what it traps, but: I guess I should have gone last Sunday...

      What brakes on R34 GTT(Europe)

      By GTSBoy · Posted

      310mm rotors will be avilable from Australia, Japan, and probably a few other places. Nothing for the front can be put on the back.

      The filter only filters down to a specific size. Add to that, the filter is AFTER the pump. So it means everything starts breaking your pump even if its being filtered out.

      Just like in being 14mm too small (296mm) makes it not fit, being 14mm too big (324mm) it also won't fit. You want to find the correct rotor.

      @GTSBoy Ok so that was the shops problem...they showed R33 rotors on R34 page and i did not know 296 do not fit(and are for R33) Yes i bought "kit" with rotors and pads. Pads are ok(i have GTT calipers front and rear). They have some 324mm but no 310mm. So i dont know if they would fit. I have 17inch LMGT4s So another question. Can i fit those in the rear or they are just "too" big for that?
