    spark plugs are just NGK LFR5AIX-11 for the iridium, or PLFR5A-11 for the platinum. you should be able to get these just about anywhere.

    I swapped my ball joints about 4 years ago, I bought the SPD ball joints from conceptZ, they are still working, but the boots fell apart after a few months. I notice they don't sell these anymore, maybe that is why. I ended up buying the replacement poly boots, which haven't split, but they open a gap when the suspension compresses, so I don't recommend them either. No idea about the Mevotech ball joints.. I would be surprised if you can't find these ball joints locally too, just search for 350Z rather than V35 That said, if you are going to the effort of pressing the ball joints out/in the steering knuckle (which is a pain of a job), the why not just also go with new bushes in your current LCAs? you can get the superpro poly bushes locally.

    My Q50 doesn't even have 'goop', it comes standard with runflats, so no spare, no jack, no goop, nothing. No idea what the JDM models come with. I bought a 370Z donut (needs to be at least 18in to clear the akebonos), a spare jack and wheel brace and I throw that in the boot when I go out of town, saves having to spend the $$ and endure the downsides of runflat tyres. Apparently if you are creative, you can make yourself a replacement boot base out of high density foam and fit the donut under the boot mat, but you lose about 100mm of boot depth.

    There isn't that many cars yet that are using electric coolant pumps, but they are slowly becoming more common, especially in the euro brands. back in 2009, they were quite rare, pretty much all were either timing chain or accessory belt driven. That said, the VQ37VHR isn't an uncommon engine, so any decent mechanic should be able to replace the water pump. I don't live in NSW, so can't make any suggestions.

    Ah, yeah, the diff bushing in the rear subframe, this has been a problem since the start of the V35 in the early '00s and the only solution ever offered by Nissan is a whole new subframe. Since they are fluid filled, as soon as they form the smallest crack, they leak brown fluid everywhere. The aftermarket options for the v35 and V36 aren't suitable for the V37 either, Z1 has built an aftermarket option, but a few people have had issues with it. The brace should reduce movement in that bushing, so should extend its life! Did you notice any increase in noise from the driveline? I know some have installed solid subframe collars and complain about the amount of noise it transmits through to the body, but not sure if the diff brace makes any noticeable difference?

    Nice, they are pretty common mods in the US. Have been considering sway bars for my Q50 Hybrid. Given it is AWD, I don't really have any wheel hop issues on hard launches, so I am not sure the diff brace would help as much as it did for you. I'm surprised the diff brace made any difference to shift feel, since it doesn't impact the auto transmission in any way, if anything I would have expected to feel shifts even more as there is less 'give' in the diff mountings to soak up the shift shock. Are you sure this one isn't placebo?

    215/45/18 tyres are probably a little on the low side compared to the factory tyre, it should be closer to a 245/45/19, which will get you about an extra 11mm of height, and should make you speedo read a bit closer to reality. 245/45/19s will be a bit too far the other way and you risk a speeding ticket as your speedo might read slower than your actual speed. 245/40/19s would be correct if you are going to 19in rims, they will give you a similar total diameter to the 245/45/18 tyres.

    I would be starting with this wire, when this is grounded, it engages the relay that supplies power main to the ECU and a few other items. I suspect this relay should NOT be energised when the ignition is turned off. Either the ECU is faulty and is grounding this pin on the ECU full time, or there is a short to ground somewhere between the ECU connector and this relay. Pull the relay and use a multimeter on ohms between pin 36 (I think it is 36) of the IPDM and ground, you will likely measure near enough to zero ohms. Unplug the ECU and check again between 36 and ground, if it is now open, it is likely the ECU at fault, or something telling the ECU the ignition is still on, if you are still measuring something similar to the first measurement to ground, you probably have a wiring problem. If you can unplug the IPDM, do that, if you still measure low resistance to ground at that relay connector, the issue is in the IPDM, if you are now measuring high or infinite resistance, the issue is in the harness.

    at $45k, might be why they are still for sale. Redbook range is $25-33k for a 2018 RS. There is also a 2019 400R for $62k and a 2020 for $56k on carsales. So I would expect a 2023+ to be more. Personally, I don't think the JDM version looks much better, tails do. but front? meh.., so for that sort of $ difference, I would take a late AuDM Q50 and put a bit aside for new turbos when they go, but everyone has their preferences..
  10. sonicii
    you can pick up a 2018 AuDM RS for around $30k, can you really get a 2023 JDM V37 for that? If so I may need to consider one...
  11. sonicii
    when you pulled the ECCS connector, do you still have 12V at pin 31 of the IPDM, if you do, this suggests a problem with the relay (which you probably eliminated by swapping relays), or a wiring problem between IPDM pin 36 and ECCS pin 31. ( I hope those pin numbers are correct, they are a little hard to read). As Duncan mentioned if you have a short to ground on that wire, it will keep that relay engaged all the time.
  12. sonicii
    As above, I would be looking into why they relay is engaged when the ignition is NOT on. If there was supposed to be full time power on this circuit, why have a relay there? 400mA may be perfectly normal when that relay is engaged and not indicate a faulty item supplied by that relay.

    What does the JDM V37 400R offer over the AuDM V37 Q50 RS? Other than a newer build?
  14. sonicii
    yeah, that's not a VQ hybrid engine, it isn't even a VQ35HR.. that is a VQ35DD, which is a bit of a unicorn, only fitted to a couple of vehicles, but definitely not the hybrid. It is a direct injected engine for a start, the HR isn't.
  15. sonicii
    hmm.. maybe you just need to go up to a 6pk1190 or even a 6pk1200
  16. sonicii
    something isn't right there, the last one I bought was a 6pk1170, which is 10mm shorter and it fitted fine. are you sure everything is stock?
  17. sonicii
    problems like that under heavy load is often spark related, either plugs or coil packs. As above, the lack of a CEL doesn't always mean all is healthy on the ignition front.

    I would agree with Duncan, although I have the Q50 Hybrid, the drivetrain is pretty much identical. I haven't had any issues at all with mine, it is a 2015 model and I have owned it for just over 3 years now. My local Nissan dealer won't touch it, I asked them if they can do a DAS wheel alignment (not sure if DAS was on the Fuga), and they just refused, saying they don't know anything about working on Infinitis, so no way would they be interested in touching the hybrid system. If you happen to live somewhere near one of the ex-infiniti dealers/workshops, they will probably more willing to help. @Duncan what battery is $5k? maybe the Fuga pack is different, but for the Q50, the complete battery pack is about $12k from Japan, or an individual cell module is around $1,200. Although once the car is a few years, Nissan recommend replacing the entire battery pack if you have a module fail.

    If you have an AuDM Infiniti G37, my first suggestion would be one of the ex-infiniti dealers, like Brighton. however, if you have an imported V36 Skyline, then I am not sure, dealers can be a bit finicky about imports.

    Yeah, tongue weight or 'downforce' is usually 10% of the towbar's rating. So a bar rated to tow 1500kg will often have a downforce rating of 150KG. To get a weight of around 225kg (I'm not old enough to speak in lbs), you will likely need a 4WD or similar vehicle, I have never seen any towbars on regular sedans with a figure that high, maybe it was an option on the old Falcons and Commodores? What fuel economy are you seeing? my old V35 6MT returned around 11L/100km in the city and around 7.5L/100 on the highway, which I thought was pretty good for a large 6cyl with a performance focus.

    They have had a few unexpected issues with the VR30DDTT in USA, turbo failures, at least on some of the earlier models, with some suggestion they have fixed this with updated turbos fitted to the newer models. Also reports of porous blocks, which is a bit concerning. I am not sure if, or how common these issues are on AuDM or JDM examples. I am kind of happy I picked the Hybrid, performance is only slightly down on the RS and there are no tuning options, but fortunately that works fine for me. The newer RS models did get some nice suspension options though! Hybrid was never an option on the Q60 though!

    Intercooler coolant uses electric pumps, they might have a 2nd pump on the RS. I didn't think they had 2 separate systems on the RS, maybe just a higher coolant flow and larger heat exchanger on the front.
  23. sonicii
    I believe we had much the same mechanical spec as Japan, there is likely some tech/feature differences though. 400R is the same as the Red sport, and if you want the AWD version, then it is Hybrid only. The US had a bit more variety, they didn't have a diesel option, but they did have the VQ37 powered version and AWD as an option across more engine varieties (VR30, VQ37, Hybrid). Also fairly certain you can get the Red sport (400hp) in AWD in US. Not sure on all the mechanical differences with the 2 VR powered options, I believe there are extra sensors on the 400HP VR compared to the 300, not sure how much that matters if you want to tune the lower powered version. They also had a larger water intercooler on the RS.

    Possibly, but you are really going to struggle to find a tow bar for it, especially one that is ADR compliant so insurance will still cover you when you are towing. The whole rear of these is aluminium which significantly limits towing weights even if you can find a tow bar. 500kg may possibly be in range though.

    Welcome! I haven't tried them, but unless you can get them for RHD vehicles, I would avoid them, LHD headlights have the wrong light pattern and it will shine in oncoming drivers faces and significantly increase you chance of a defect. Also, a GT350 is a Mustang, you have a 350GT.
