Having done a similar mod on my '06 Corolla wagon, the biggest issue is likely to be a lack of pins/wires in the clock-spring if your model never came out with an option for SWCs. You may need to source a clock-spring from a different model which has the right amount of pins/wires for the functions you desire, as well as the dashboard-side wiring to attach to the headunit.

Highly doubt it, the RZ was just a runout sticker-and-alloys job before the facelift came in, the only thing headunit-related that might make a difference is that it had the sat-nav option as standard. The manufacturer is just trying to find an excuse to get out of the problem as the RZ probably doesn't appear in their system (and some mobs automatically try and waive responsibility for anything as soon as you have something that isn't _exactly_ what is in their database)

If the gearbox is the original one for the car it will be stamped on the build plate on the firewall. Pretty sure it should be an S51 or S53.

The "sound" of a submerged in-tank fuel pump priming the system is often not audible from the driver's seat, if you're outside the car or have the back seats removed you'll be more likely to hear it, it'll just be a faint high-pitched hissing/rushing sound much like an aquarium or pond pump.

Yeah, if you're travelling on typical country backroads you do _not_ want coilovers, especially not cheap eBay-specials (which have a tendency to be bone-rattlingly hard)

In 99.9% of cases, suspension units are different front and rear. The coilovers in the eBay ad are for a full kit of 4 (2 front, 2 rear) and you can see slight differences in the pictures between the two (top hat design, brake hose/sway bar tabs etc). HOWEVER - that ad is for a set of coilovers, not factory replacement struts. They replace both your existing struts and springs, and are designed to be a "performance" product for improved handling, lowered ride height etc - if you're just looking to replace worn-out factory struts you need something like KYB, Gabriel or Monroe struts, not coilovers (note that replacement struts are often sold in pairs, coilovers almost always in full sets). Also, they're **** - if you really want proper decent coilovers you're normally looking at $1k+, maXpeedingrods are cheap for a reason and are basically only for people who want to slam their ride and think they're hardcore drifters but can't save enough money on their Maccas burger-flipper wage.

The amount of sales going on for Nulon lately makes me think they're either gearing up for a new product launch (and trying to get rid of old stock) or with the oil market volatility and state of the world the way it is as the moment they've every greatly over-estimated demand or have lost a significant amount of overseas customers and need to recoup sales/move excess product.

Yes, Supras did have digital dashes and TEMS suspension options (at least on the grey-imports, not sure about the locally-delivered models). Things are getting strange now though, you say it was imported in to QLD yet that VIN shows up as an Australian-delivered model (it would still have been made overseas but the importation and compliance would have been through Toyota). Also, why would someone replace a 7MGTE with a 1GGTE unless the original engine was blown up (yes I know the 7M has a reputation for killing headgaskets, but the fix is relatively simple/cheap and there is much more potential in a 7M than a 1G)

Is there no kind of intermittent function on the wiper stalk at all? Very strange for 2005 even for a base-model fleet special. EDIT: Redbook seems to indicate that the 2005 Workmate should have intermittent wipers, so that makes me think you're referring to the variable function. In which case I wouldn't be surprised at all if you can swap in the variable stalk from an SR or SR5, I did the same with my '98 Corolla (actually used a Camry stalk which was almost identical) in order to upgrade from fixed intermittent to variable.

Also, "Lexus" Estima? Dollars to donuts the importer slapped a set of Lexus badges on what was only ever sold/made as a Toyota...

Just like how Toyota doesn't use just one PCD across their range, same goes for other manufacturers. Lots of 5x114.3 (for the widebody Camrys) options out there, you'll need to work out offset ranges though as it is one of the most common PCDs around so there will be all sorts that will have the right pattern but foul on guards/suspension etc.

What makes it "TRD"? Also, you're going to need to provide a lot more details if you're looking to sell it, and should also create a proper For Sale thread rather than just a general post.

I can't remember the exact bill of materials required but I know you can convert between 4x100 and 5x100 using ZZT231 Celica parts (and vice-versa, converting the Celica to 4-stud). Why you would want to I don't know, as Celica-offset 5x100 wheels aren't anywhere near as common as 4x100 stuff.

Fair bit of labour on a FWD V6 to change the rear spark plugs, especially if done "by the book". Also I'm assuming parts costs are in here too, as you're looking at $100-150 alone just for the plugs if you go with iridiums (which are usually recommended at least for the rear bank to extend the replacement interval to avoid having to disassemble half the car every 30,000k for copper plugs) Still, $2k sounds like way too much ($1100 is closer but still a little high) Is there anything else being done in the service that you might have missed? And is this at a dealership or a private mechanic? Is it a logbook service (if so, which month/k service?) or have you asked specifically just for oil change and spark plugs?

Grade? Quantity? Regardless, this information should be in your User Manual, and may also vary depending on the market since your profile says you're not in Australia. And if you don't have a User Manual for whatever reason, then either contact Toyota directly or use an online oil selector guide from one of the reputable oil suppliers like Castrol.

Is there any kind of manual shift mode for the auto? Can you confirm what gear it's actually in? Have you accidentally hit a "Sport Mode" button or the like? The symptoms sound kinda like a torque converter that isn't locking up fully, or a transmission that has a lockout for top-gear/overdrive that won't engage unless certain conditions are met (like temperature, or an on/off button)

@Bens1xx you posted a thread barely a week ago asking if another 15W40 was suitable for your engine, and were told there that the correct oil was 5W30 or 10W30. Also, don't shop for car parts at Coles or Woolies. You wouldn't buy potatoes or nappies from Supercheap Auto, would you?

Synchro rings require a full disassembly and rebuild of the gearbox, ~$3k isn't that unreasonable if they are supplying parts as there is a lot of labour involved

Definitely mid-late 90s common Toyota/Fujitsu Ten head unit, might be hard to pin-point it down to a specific model as they tended to use similar units on most of their range (and each model often had 2-3 different variants too). That one in particular shows up in my '97 Corolla owners manual as the Type B (although it doesn't have the separate CD player controls so yours probably comes from something like a higher-spec Camry), but both of mine had the Type A fitted (where the screen is on the left rather than the middle, and a few other buttons re-arranged)

Not sure on the effect of industrial oils, unfortunately our petrol prices are impacted much more by Singapore/Tapis than Brent so it might be a bit longer before the drop hits our part of the world (looks like Tapis tends to follow Brent fairly closely but always be more expensive relatively)

6L is an annoying size for me as generally Corollas take ~3.5-4L, so a 5L bottle was always good for having 1L spare left over for top-ups/emergencies. Although now that I think about it, if I get another 6L bottle then I would have enough for 3 full changes (I don't like leaving oil bottles half-full for really long periods of time though if I can avoid it, especially if I'm relying on it for a full change)

If it's anything like my parent's '96 Camry, if you don't close the boot lid properly with the car locked it'll beep the horn too

This is just the pedant in me coming out, but Aisan and Aisin are two completely different companies. Both are deeply associated with Toyota however - Aisan will be mainly engine components (historically carburetors and fuel systems) and Aisin will be predominantly drivetrain components (although they do engine stuff too along with just about everything else)

Wheel PCD should be 5x114.3, stock wheels were most likely in the range of 14x5" or +27 (that's what the next model MS65 had from my brief search). Tyre size will be harder since most catalogues don't go back that far, and from factory they would have been running cross-ply tyres or radials with 82% aspect ratio (early radials were pretty much all the same sidewall aspect ratio so the tyre code didn't list it, just something like 185R14 in a similar vein to commerical truck tyres)

Yeah remote boot release just means you don't have to be standing physically at the lock to open it. My '98 Corolla lists "remote boot release" but it is 100% just a lever in the cabin even on the highest spec.
