Hi

My car is about to hit 50000kms and im gonna get it dyno tuned just to up the boost slightly and wanted to put some new plugs in it. I have priced some plugs locally and apparently the R34 comes standard with platinum plugs? is this true? If so im guessing i wont need to really change them as they are good for 100000kms arent they?. Can anyone tell me if iridium plugs have any advantages over platinum? and are they gonna be any good if the dyno tuner wants to change the gap for performance benefits?

Any help would be great

Thanks

This question gets asked every couple of weeks. The search button is ur friend, use it.

Quick re: iridiums have no advantage except longevity. U may have to regap if running higher boost.

Well according to NGK the Iridiums do have advantages over Platinums. They last longer for one thing.

I think that the V-Groove regular plugs I had were stronger sparking (at the same, 0.8mm gap) than the Iridiums. I'm about to put V-Grooves back in, to replace my 35,000(ish)km old Iridiums.

      yeah first and reverse is where you will find clutch release issues (whether hydraulic or mechanical) because the difference in revs required is the highest there; particularly changing down from 2nd to 1st when still moving. To be clearer though, it is possible that the clutch release bearing is the wrong height. This is less likely than a hydraulic issue but it is not unheard of when you are mixing and matching

      Replacing turbo water line - any recommendations or advice?

      By jtha7 · Posted

      Hi all, Restoring r33 series 1 rb25det. All the heater hoses were on their way out, have replaced them and put it all back together. After testing I noticed a small leak from behind the head on the actual metal water line to the turbo when cars warm. I tried running a longer hose over it but it kept leaking...   I am about to take the (stock) manifold off again😔 to change the water line does any one have any lines they recommend? I was looking at Aeroflow Turbo Oil & Water Line Set but not sure what everyone else recommends. Car is completely stock but want to upgrade turbo eventually. it looks like ill have to disconnect a lot just to replace these lines so if there's anything else recommended to do please let me know. Thank you in advance!

      RB20DE NEO smallbox clutch.

      From memory, on the R33 GTSt at least, while everyone says "It's not adjustable", I found when I changed clutches in mine, it just needed a small adjustment on the rod length. But be very wary here, as you could end up trying to push the pushrod in the master too far, or blowing out the slave.   Most likely though, if the master/slave isn't bypassing internally or leaking out, then the throw out is the wrong height compared to the fingers on the clutch, so when it moves to disengage the clutch, it isn't 100% disengaged. You can check part of this out too by jacking the car up, having the engine running, put your foot on the clutch and try to engage 1st gear. If it goes in pretty easy (Compared to the ground) and/or the wheels start turning a fair bit and it takes a bit too much brake pedal to bring them back to a stop, this is likely the issue.  I'm not sure if you can adjust the height of the forks etc in these though, it's been that long since I've touched any RB gearbox.

      That's all good, I thought I was missing some interesting feature! Maybe @PranK can double check if that is something that is meant to be operating or not.
