I order a fair amount of parts from Japan(Amayama) and it takes roughly 2-3 days to arrive in Quebec snail mail. 1 day if you pay extra.  If you're in Australia which is much closer, should take half that. 

As a long time customer, Amayama is pure shit at the moment for Australia. At least a 3-4 month wait if you are ordering multiple parts. Amayama have an office in Australia (Sydney), UAE and Japan and not all parts are stocked in Japan - some are US, some UAE. For Australia they don't specifically order and ship your parts to you from supply point either - they bulk order to Australia warehouse to keep shipping down which is why their supply to us sucks and takes ages. Having a local office here is actually a disadvantage because of this now - called the Sydney office yesterday as I have an order of nearly 4 months getting held up by still awaiting one part !

At least if you order genuine stuff from RHD, Nengun or JP car parts they exclusively source your parts within Japan and send direct to you from Japan.

Amayama prices have been completely nuts for a while now. Almost anything if I can help it I order either through a local dealer if the part number is listed in the US parts catalog or from US-based dealers that will import/stock JP-only part numbers on a special order basis. They only use surface mail though so if they don't have something in stock it will be 3-4 months.

Damn 4 months is ridiculous. and I thought my 10 week wait in february took a long time.

I've noticed the only advantage with using Amayama is with large oversized items which would be costly using international shipping.

That's not even true either. I went to purchase a second set / pair of 32 outer sills which are over a metre long. This was going to be about $1250 -$1300 for them - and shipping with TNT / FedEX on top was going to be over $1400 !

When I got a set through RHDjapan it was about $550 with DHL...

You want fast oem, Ive gone back to these guys in Kyoto this year who I used to use years ago over Amayama - can't beat them for speed on oem parts but RHD is close. Both 100% reliable.

Interestingly enough Amayama ears must of been burning as my last part is here this arvo and will ship entire order tomorrow from Sydney.

I suspect it's because you're in NT. local buyers in sydney can just choose pickup.

yeah RHD price is consistent. they offer consolidation free of charge and don't overcharge on shipping.

@BK @TurboTapinWas having similar frustrations with Amayama. I tried to order a while ago, but they quoted me $1500 to ship to Canada, and there was a 3.5 month lead time -_-

@GTSBoy @Dose Pipe Sutututu I fixed up the rubber boot, but still seeing the timing go way back to 5* on warm up. I hooked up my smoke machine again and I see it's still lightly leaking from that area. I may try some heat shielding tape to really seal off that area for now just to see if that makes any different.

Try closing up your IACV a bit, could be now there's too much air being bled back via the IACV and your factory ECU is shaving timing to keep the idle at target.

This is why I love DBW, you piss off the IACV and AAC air leaks.

If you're in Canada just go to your local Nissan dealer for parts. We're one of the few country's that seems to still be able to order JDM parts through dealer. Cheaper as well as there's no middle man. 

I get small things that are cheap to ship from Amayama when I'm too lazy to drive over to the dealers.

Cheers.

@Dose Pipe Sutututu I assume you mean by adjusting the idle screw?

Correct, try unplug the idle plugs, unplug the TPS and adjust the idle screw till it idles just a tad under the target RPM.

At the same time, you might as well check your base timing and also set your TPS.

(All the above is complete waste of time on an aftermarket ECU as you can offset the lot, except when there's too much air allowed through the IACV).

Yesterday I adjusted my base idle and set my TPS. Im still getting 5* ignition timing on warm up.

A few things I did notice yesterday tho was, when I put my key to On, my IACV starts buzzing. I cleaned it again and also captured a video of what its doing when it gets power. Is this normal for these things to buzz?

 

I also took some logs of my car while idling, I noticed occasionally in the software that all the guages would just end up going to 0 for a few milliseconds, and then return back to normal. Does this mean a short somewhere? Or is it likely that its just a software bug. First time I've ever seen this and I've used datascan quite a bit.

Ignition timing during engine warm-up is going to be a bit of a mess. The NEO IACV has two parts. One is the solenoid valve which is almost certainly never going to fail. The other is a coolant temperature controlled thermostat that meters more air when coolant temps are low but closes up as the coolant temps go up. This is the part that I'm worried about leaking excess air assuming you don't have any other vacuum leaks. If it doesn't close up properly the idle target will drop because the ECU sees coolant temp has reached a reasonable target but the actual thermostat isn't closing up properly and that's causing it to have to yank the timing out to get there. Maybe with hot enough coolant it finally closes up enough to have sane timing values but still low side of what you should be seeing.

Also, if you see the ECU connection dropping out I would make sure your USB connection is good first and foremost. I've had a lot of issues like that due to a bad USB cable. Also verify the consult port is connected properly and there's no weirdness like loose pins or other damage to the connector. Then maybe check the ECU capacitors?

Ahh, didnt think it may be a connection issue with the laptop, but that's probably right. I'll double check the connection next time.

Is there any way to figure out if the coolant thermostat on the iacv is working correctly?

I don't know why but there is no mention of how to test the cold start valve on the AAC assembly. I would only look closer at the cold start portion if you have normal ignition timing once the car is warmed up but you see less timing when the engine is cold.

    • Just trying to get my head around this. At 5psi of boost, you turn on your wmi pump, and then you're using a 3000cc injector, to allow flow upto the actual engine, where you have your 6x200cc injectors and a 500cc injector. If the above is correct, what advantage are you obtaining by having the 3000cc injector blocking flow, is this just incase a line breaks between that injector and the motor you can stop flow immediately? Or are the 6x200cc and 500cc less injectors and just spray nozzle?
    • Welcome! New member myself, but I had an R33 back in 2002. Best advice I could give, based on my experience: if you're running the factory turbo, be very conservative with boost. I made the mistake of just fiddling around with the boost controller and cranking the boost for fun, and the end result was my intake pipes popping off frequently from the constant deluge of oil that was being blown into the recirc by the stressed-out turbo, which itself was siphoning oil from the engine and farting it out both sides of its centre bearing (or something to that effect). If I could do it all again, I would have gotten a new turbo and had a tune dialled in professionally and then just left it alone! Funny you mention the metal shavings in the gearbox, as I had the same thing - the probe plug (magnetic drain plug, essentially) would come out caked with shavings. At least it was doing its job. Not sure if that's just sacrificial wear and part of the deal, or if my gearbox was shagged, but I wasn't abusing it. Enjoy the R33 - they're a dying breed, and if they weren't $35k+ on CarSales in Queensland, I might have picked up one of those again, instead of the 370GT I own now (though I'm loving the 370GT, that big 3.7L V6 just hits different).
    • Howdy folks. I owned an R33 back in 2002, which was thoroughly beyond my capacity (financially speaking) to maintain/insure, so we parted ways in 2004. Fast forward 21 years (to literally yesterday, in fact) and I'm now the proud owner of a 2007 V36 370GT. I'm happily surprised by how much power the VQ37VHR makes, compared to the RB25DET, considering the latter is turbocharged. I had planned to add a turbo at some point but I'm on the fence about whether I'll even need it (though I do love the sudden onset of extra torque). Any other 370GT owners around the traps, I'd love to hear about your experiences with this car (good and bad).
    • Perhaps the answer is... more jacks!* *proper jacks must be used.  
    • I NEVER think about using a scissor jack unless there is absolutely no other alternative. f**king things are dangerous, annoying and stupid.
