  1. Actually I mean this one, after a check. (the 90 was for the diff) 🤣 Is this bad? I was surprised to see the amount of tiny steel shavings when I drained it after about 150ks, due to the clutch balance problem. Since I do not race and I am not pumping high HP through, it is this oil a good choice and how often do I change it? We are only talking a few thousand ks a year.
  2. I am running Penrite 85-90 full synthetic. He reckoned I should not play with difference oils. As I saw someone comment that they think the synchro's in these like mineral oil more.
  3. Or to be a bit more specific. The 5 speed gearboxes that are built to take the RB25DET (turbo engines). The R33 GTS-T and the R34 GT-T came with them. Also the 300ZX Twin turbos, came with a similar gearset. A modern version is the CD009, which comes on the 350-370Z, 6 speed. They physically look stronger better made with extra gussets etc. Basically these are the go to gearbox for people wanting a reliable gearbox for high HP applications. By the way I had mine checked by a local mechanic and he thinks it is fine, just needs some more miles to be clocked up on it. The vibration was due the the Nismo pressure plate being out of balance. Had to pull it out and get it balanced along with the brand new billet steel flywheel. I would have thought they should be good from the factory already.
  4. Yes, I do notice that when in gear the idle raises, cause I plumbed up the neutral switch. That is when I feel the miss/vibration the most. Anything else that I should be concerned about? But I am going to clean the IACV.
  5. Yeh, I thought about that. What difference will it make?
  6. Thanks for the feedback guys. Yeh, the timing does jump to 15-20, when you take it up past idle. This was taken on idle. It does have a high idle sometimes. GTSBoy are you saying that IACV is faulty then? Any way to test this? Cheers
  7. Cleaned the AFM and throttle body. Still no change. I am starting to wonder if the flywheel or pressure plate is out of balance and what I am feeling is a vibration. It does increase with revs and there is a small vibration on the clutch pedal in the high revs.
  8. Thanks. I will clean it and check the wiring. But I have not changed it during the conversion. I think it is OG. I wish I had a boost solenoid. NA. It does rev right out. It is just missing a bit and feels like a vibration in the lower revs.
  9. So every since the conversion if have a miss-fire. It seems to happen in the rev range of 1100-2500. The car was sitting for a few months during the conversion. 1. Changed the plugs 2. Coil packs are brand new 3. Unplugged coils one by one, they all display similar behaviour 4. Sprayed all over vacuum hoses etc with brake cleaner, can't hear anything change 5. Vacuum tested when running, looks normal. 6. Unplugged the O2 sensor, no change. ecutalk is seeing voltage. 7. Swapped CAS with another good one 8. Resistance check the coil loom 9. The battery was disconnected for weeks during the conversion, so the ECU has been reset. I have a consult (ecutalk), but I don't really know what to look for, other than error codes, which there are none. I am running out of ideas. PS It is a N/A

  11. Just put in a brand new RB25DET big box, auto conversion. Last time I drove manual was my 260Z, 15 years ago. But this box seems a bit notchy shifting up. Are new gearboxes like this? Do they have a break in period? Also noticed a vibration on the clutch pedal when shifting close to red line. It is R34 box, with a pull clutch. I installed a new Nismo sports clutch with a slightly lighter flywheel. I am running Penrite Pro Gear 75W-90. Cheers
  12. Did you get this sorted? I am in the same position. R34 bigbox with a pull clutch and a R33 master. Pedal basically drops to the almost the floor then starts working. Does not return under its own power. This is a new build as such, conversion from auto. I am pretty sure I have bleed the master and slave, at least I can not get any more air out.
  13. This is interesting, suggests there is a correct orientation for the flywheel. To which the dowel will assist in getting it right. So as long as you align the dowel holes should be all good, right? https://www.enginebuildermag.com/2009/08/dowel-pin-alignment-caution-for-nissan-engines/
  14. I ended up buying this one. https://www.rhdjapan.com/nissan-oem-5-speed-manual-transmission-er34-rb25det.html I have just taken delivery of it. With the current exchange rates, shipping, and GST, it came to about $4k NZD. Shipping took only 14 days once they had it in stock. Delivered to my door. But I did have to wait about two months for it be in stock. It was fine, as that was roughly the date specified when I ordered. What you see on the website is exactly what you get, pull clutch setup. OEM parts to convert come to about $330 NZD. But I got a Nismo pull clutch to go with it (on top of the $4k)
  15. Is there a difference between a push and pull clutch flywheel? I am looking for one to match a R34 big box that is original, ie pull. Putting in a Nismo sports single plate organic.
  16. Thanks. I was not sure if there was some sort of fluid transfer difference.
  17. Great answer, never had that problem on my 260Z though. Must have been lucky. I had wondered why Nismo made that pivot ball. I think I am going to just get the Nismo pull clutch and keep the box standard. Anybody know if there is a difference between the R34 and R33 master cylinder. Do I need a R34 type as the slave will be a pull type. Will a R34 fit my R33 or will the stock R33 work anyway? I guess the R33 GTR is pull, but doesn't have some sort of booster?
  18. Unbelievably, I can not seem to find much about this subject on SAU. Maybe my search button is broke. I have have done a fair bit of Googling, but get mixed messages. You would think that since most GTRs have them and Nissan moved to them with the R34GTT, that it would be superior, but I see a lot of people converting, I can only presume because the market seems to be more varied. I am getting my hands on a new R34 big box which comes with a pull clutch setup. I am interested in peoples opinions of the pull system and if I should convert it to a push ($300). The application is street driven R33 ~350HP, which I don't intend to drift or do burn outs. Seems that the options for pull clutches are limited and they generally are more expensive. Is that just because they are more beefy? Considering an Organic Nismo Sport pull Clutch which will cost me about $800. Thanks for sharing your thoughts and experience.
  19. It's an interesting find and thanks for sharing. I also could not believe the size, when I first replaced mine. Looks like something from a Mazda Demio. Tempting to try it. But looking at the seal diameter the Z145A, which, according to Supercheap is the correct one, is 63mm and the Z115 is 70mm. I have not measured the mating face, but presume you have and their is no chance of it extruding out. I wonder if modern filters are made in such a way that there is more surface area, that is how they reduce the size. I see the K&N one is even smaller.
  20. I am an idiot. I thought I had checked Nengun. Thanks for the reminder. You know when you have like 50 tabs open. They are much cheaper. NZD $ 2,502 for the box about there is an option for $795 shipping. Now I am seriously looking at this. The best I can find locally is a RWD converted R33 GTR gearbox for $3,000. That is what I mean by stupid prices. My next question, which I have asked of Nengun, is what other parts do I need to add it. I think it comes with a pull fork and thrust bearing. No speed sensor, clutch, slave, shifter. Looking at the pic on the site the part number 32010-AA520. https://www.nengun.com/oem/nissan/32010-aa520 It looks like I need to source the brackets and hoses etc. I am doing an auto conversion. I was looking at putting in a 20DET GB, but it seems that is only going to end in pain.
  21. So I heeded your advise and hunted down the only new one I could find. That was at Alpha Omega Racing. R34 RB25DET Gearbox Price: $3,376.00 I have to admit that it is not a terrible price. But I was quoted $1,326 to ship to NZ. Total of $4,702. I only paid $3,000 for the car, so yeah.
  22. Hi, Do you know what you have to do for this to work. Like do you have to disassemble the whole gearbox, to get the input shaft out and machine it?
  23. Hi. Very interested to see how it goes. Keep us posted. cheers
  24. Exactly. There is not much in between. R33 GTR gearboxes are cheaper, about $2k. But a lot of mucking around making them 2wd. Even a 350 2nd had box is $3k. I know this has been thrashed around here a lot, but is the 20det good for up to 300hp? They are about $1k. Like I said, don't intend to thrash it.
