This is currently being discussed on Maxima's Down Under, here:
http://www.maximasdownunder.org/foru...p=40943#p40943

While pulling my parts rig to bits, I noticed on the end of my transmission, a symbol of a Kangaroo (dont laugh!)....fair enough its an Australian J30.
My question is, do you Yanks all have Roo's on the end of your boxes? are no symbol at all?

Here is what I'm talking about...I smudged grease over it to make it more noticeable for the photo...

Other Australian members have checked their own rides and found the same symbol.
IF you guys find you dont have that symbol, my next question is, how do OUR Japanese produced Jatco gearboxes differ from the rest? does anybody have a clue ??

PS: VG30E Automatic transmission, 1994 model

My GXE tranny has no kangaroo on it. But mines in Canada.

 

I looked up that thread that got locked last week (or week before) "GXE tranny if anyone is curious" or whatever its called, and zoomed right in....Noooo Kangaroo for US GXE boxes.

Canada also use primarily KMP/H....
Manual or auto box ?

 

all GXE's are auto. manual was SE only in the USDM.

i think the trannys are the same... maybe some slight diffrence from RHD vs LHD but the USDM trannies are from jatco also.

 

I wonder if anything else is different?

for example, a different gear ratio for AUS market?

Kind of strange they would put that kangaroo on there for no other reason.

 

"Yanks" have a symbol of world dominance at the end of our transmissions.

 

It's not a lie - if you beleive it

 

Just a stereotypical, sarcastic statement. I'm not serious. There's plenty of places in the world I think I'd rather live than the US. Although Australia isn't one of them. I have to say, i'm a bit jealous of this 5 speed A31 Nicco has on the way Lucky Australians have no import regulations.

On the other hand I could always get a Ford Thunderbird and badge it a Cefiro

 

Plenty of regulations here, different systems for different types and ages of cars, is alot easier to get an A31 than say, an R34 GT-R V Spec II nur. Compliancing an old car here is easy. Giving a good reason to import, and compliancing newer vehicles is the hard part.

On the other hand, you could have a bowl of rice ??
LOL, come on, there are A31s in the states, find one

Difference between LHD and RHD should be basically non-exsistant, and isnt Canada LHD anyway? I was going to suggest the symbol being/not being there based on metric/imperial measurement of speed, but again, no physical difference, our gauges mark both systems of speed, and US GXE models with digital clusters can switch between MP/H and KMP/H, I believe?

Where can I find the gear ratio' numbers for the US spec tranny's?
Seing as I've usually got time to kill, instead of throwing the thing away I might rip it apart and have a look....?

Also worth a note, this "stamp" isnt inwards on the metal, it was outwards, so it was marked when upon production, not post production by any shipping companies / gearbox overhauls, anything like that. Its just a really weird mystery.

 

My South African 300E (VG) has a Joey on the box

 

Im fairly sure this has something to do with final gear ratio's.
Here's why.

Apparently the J30, stock, will max out at 210kmp/h

Mine runs 100kmp/h at 2050rpm, and tonight ran 200kmp/h at 3350rpm....nowhere NEAR the redline, plenty of guts left.
My last J30 also ran the same RPMs.

Any US Members, what do your rides top out at, and what is your 62mp/h RPMs?
LvR, same question ?

Consider any modifications and ambient air temperature.
I have no mods on this new girl, low voltages, bad mounts, and the ambient air temperature was 16 degrees Celcius according to the climate control. No overheating, and yes, I am certain both my speedo and tacho are dead right.

 

My speedo and GPS both agree with the current std (205x65x15) fairly new tires on my vehicle - 120kph@2500rpm.

Puzzling that ito both maths and the mechanics involved in rotating tires - assuming your converter's lockup is actually working correctly, I would have expected 4100rpm@200kph .

Never seen 200kph on my old and original auto box with 300k km on it yet, but extrapolating from what I am used to actually seeing on my speedo/rev counter, my guess is 3300rpm will only get me to maybe about 170kph

Dont know where its gonna top out at, but my box is old and I value it so am not gonna try and find out - sorry

 

my VG auto did 100kph at around 2200rpm (US spec) so maybe they are different.

 

Im running stockies, 120kmp/h will usually pull off around 2200-2300 RPMs...on my old girl it was lower (usually ran 100kmp/h at 1900-2000RPMs on a regular basis).
Either to do with my voltage/grounding problems of adjusted timing, I get this huge surge of power at 3000-4000RPM.
Even on your calculations, 200kmp/h @ 4100 rpm, nowhere near the redline, so obviously the top speed is alot higher than what has been said.
Apparently the VE's will top out at 210kmp/h

On the note of different gear ratio's, acceleration is apparently 0-60mp/h in 9 seconds, stock, bull****, stock is more like 7 seconds, if that, for me.
Again, any US Members care to confirm this ?

 

my vg auto 0-60mph time was 9.8s..... what the hell kind of juice are you running on?! i want some of that!

 

i duno about VEs down there but i have easily touched 230kph in my VE auto and probably could have gone more farther if i wouldnt have seen red blue lights ....so i duno why u r saying that VE's will top out at 210kph... and i m sure its not the only me that have gone to that speed in VE...

 

Just what I've read on old reviews, and stock rides on CarDomain.
Australia received VGs and Auto's only, no VE or 5 speed .
So you think our rides, unmodified are fairly capable of going off the speedo??

98 Octane...but they say our fuel isnt as clean as yours over there.

 

i never tried going to that speed (or never got a chance to) wen i was stock...i only have CAI and opened up exhaust (straight pipes)...yes no cats, no resonator, straight through type muffler and 156000km on engine and i m capable of reaching around 240kph i m SURE.......let ur engine breath easier and u will be able to achieve better top end...

now with stock i m not sure but i dont think there should be any problem atleast going over 220kph or even better with VE...i duno about stock VG tho...i also have VG but its parked at my University and i gotta bring that home and try out VGs as well jus being too lazy...

now i m in the process of rebuilding my VE and after that i will see how quick it is to go around 240kph than now....

 

I did 142 in my stock VE auto back when I was 17 and stupid. Didn't have the ***** to peg the speedo, but it most certainly would have. I think there's some videos on YouTube of some VE guys going near 150 but they're not autos

 

i dunno... does your fuel have ethanol or not? ours is usually 10% ethanol (and this was on 89 octane... normally near me you can get 87, 89, or 93. 98 is 'race fuel' in these parts)

 

No Ethanol...only recently have we had the option of 10% Ethanol fuels, isnt available anywhere near I live, infact come to think of it, I've never seen it available at a servo anywhere in this state.

Our Regular is 91-93 (depending on brand), and premium is anywhere from 95-98 (again, depending on where its from, some places have a Premium95, and Premium98, others might only have a 96 octane available).
I notice a pretty big difference between the fuels, regular is weak as ****. Havent tried using octane boosters yet.

 

ah. yeah ethanol hurts power output. i saw some flexfuel vehicle that got 18mpg on gas, and only 12mpg on E85 (85% ethanol, 15% gas). so the purer the better. what ignition timing is your car set to in AUS? is the timing more aggressive with the higher octane fuel you guys have available to you?

 

As far as I know, its factory tuned the same as US spec models, not too sure what you mean by aggressive though, mine is set a few degree's higher by the feel of it, I get a stupid surge of power between 3-4 grand, but to be honest, I dont know if this is timing, grounding issues, could even be busted engine mounts.
On a tank of 98 octane, if I drive it nicely (including the week before so the ECU is adjusted to being driven nicely), I can push for around 700km, which I think is ****ing awesome for a 14 year old 1.4 tonne V6, in today's standards, that is still great economy, even for a 4 cylinder.
Usually I'll get around 550-650, but last night it chewed up 1/4 of a tank in about 80-100kms, it seems to learn how to use MORE fuel quicker than it learns how to use LESS fuel, typical of a fast Nissan....

 

aggressive timing = more advanced. the more advanced it is the higher risk you have of predetonation, but higher octane fuel lets you get away with more advanced ignition timing before predetonation happens. factory (15) will work with 87 octane... i know 20 will work with 93 octane... wonder what you can get away with on 98 octane.

 

And advancing the timing shifts where the peak power is (on RPM band), correct?

 

Doods, Octane ratings are different worldwide.

From the Wikipedia http://en.wikipedia.org/wiki/Researc...rement_methods

"Anti-Knock Index (AKI)

In most countries (including all of Europe and Australia) the "headline" octane rating, shown on the pump, is the RON, but in the United States, Canada and some other countries the headline number is the average of the RON and the MON, sometimes called the Anti-Knock Index (AKI), Road Octane Number (RdON), Pump Octane Number (PON), or (R+M)/2.

Difference between RON and AKI

Because of the 8 to 10 point difference noted above, the octane rating shown in the United States is 4 to 5 points lower than the same fuel elsewhere: 87 AKI octane fuel, the "regular" gasoline in the US and Canada, is 91–92 RON in Europe; 93 AKI octane fuel, the "premium" gasoline, is 97-98 RON in Europe.

However most European pumps deliver 95 RON as "EuroSuper" (equivalent to 90–91 AKI). In Germany, Great Britain and some other countries 98 RON as "SuperPlus" (93-94 AKI) is available almost everywhere. Even 100 RON (95-96 AKI), is widely sold; 102 RON at selected stations.[2]"

Their high grade fuel is probably the same as our high grade fuel therefore their timing is probably the same as a US Max.

 

oic. i knew the octane rating in the usa was derived from the average of 2 numbers (r+m)/2 where r = research octane # and m = motor octane #.... didn't know about dfferences in the calculation for different regions tho.

 

Posted this on MDU, applying to this thread also

 

If your TCU detects normal operating temps in the box (as in already warmed up) then this becomes irrelevant unless you manually somehow disengage the lockup on the TC or OD.

Above about 80kph the lockup will function .............. as will OD ............... as long as you are not at near full throttle or accelerating madly.

You need to be consistent and compare apples with apples - iow - compare speedo and rev values in the same gear at constant speed else you are wasting your time
