Question in Japan is there...

In Japan is there an actual WRX base model like the one here? or is it just a WRX STI? I know if the STI comes over, there will be a base(the WRX), and the STI will be the higher model. is it like that for Japan???

Yes there is just a WRX and the STi being the model above that. Also, their base WRX is better than ours, more power, better brakes, etc.

Default why?

There are some who say that we get somewhat diluted versions
of some Japanese and European cars because of differences
in emissions regulations, etc., but there is also the theory
that Euro and Japanese enthusiasts want to be able to say
that they have the "best" versions of their best cars.

Example: supposedly the "native" version of the WRX has variable valve timing, but Subaru went thru the trouble to
remove it for the U.S. version, even though VVT is supposed
to improve emissions and economy while allowing more power.

Japanese get a "better" base motor because the Japanese high-octane gas is higher in rating than nearly anywhere else. Emission laws are also different. Between the two, the exact same motor in a Japanese WRX would make more power and torque than if you were running it in the U.S. or Europe. UK people with grey imports know this, the cars don't run as well, or as reliably, as they do in Japan.

Other features are different for subtle reasons. Seats for Americans need to be, shall we say, wider than for Japanese. Americans care about cupholders much more than Japanese do. Etc, etc.

In Japan there are WRX Turbo (WRX NB) and WRX non-turbo (WRX NA, with 2.0L engine). And then there's WRX STi.

WRX NB is better than American version in some ways. Such as AVCS, bigger brake, semi auto A/C, sport-shift auto tranny, sport seats, and some others...

I am not sure how much difference there is between WRX NB and Euro WRX, obviously the Euro spec. engine does not have AVCS either, and Euro gets 17" wheels standard (JDM WRX NB-R gets that too)

WRX NB -2.0turbo 250ps (EJ205) there is NB-R with same spec
WRX STi -2.0turbo 280ps (EJ207) there is STi S-spec with same spec
WRX STi typeRA spec-C -2.0 turbo 280ps with more torque than STi (EJ207)

wagon is
I's -1.5NA
20N -2.0NA
20K -2.0turbo 250ps (EJ205)
STi wagon -2.0turbo 280ps (EJ207)

notice that WRX means sedan in japan. No WRX name on wagon.

*Euro* version is 218ps for 2.0turbo (EJ205).
and *US* is 227ps for 2.0 turbo (EJ205).

Recent discussions in Factory Forced Induction suggest only the STi has AVCS and the base WRX NB "amusement sedan" does not have AVCS.

10.7 @ 136, '02 WRX
12.8 @ 112, '09 spec.B


Theres three different ways to display the AKI (anit-knock index, aka- Octane) of gasoline:

RON- Research Octane Number, what Japan uses.
MON- Motor Octane Number
(R+M)/2- Average of the 2, what the US uses.

For both RON and MON, the engine is operated at a constant speed (RPM's) and the compression ratio is increased until the onset of knocking. For RON engine speed is set at 600 rpm @ 150f and MON is at 900 rpm @ 300f. MON is a more stressful testing environment.

Generally RON will always be a higher rating than MON and thus higher than (R+M)/2.

For pure compounds the differences between RON and MON range from 0 to more than 15 numbers...you cant compare the two different AKI directly, ie- Japan has 108 Octane... we only get 93 Octane..... your not comparing Apple to Apples...those gas's could be the same exact formula!!

In regards to why we get less with our WRX than Europe or Japan- its all about cost cutting. Subaru had to make the car affordable in the US, bottom line. So we get screwed out of 17" rims... and then because 16" rims arent big enough for the 4 piston calipers... they got axed, too. Damn bean counters.

Also American roads (especially in Michigan) tend to be the proving grounds for automotive suspension/drivetrain and wheel combos. Our roads are BAD! 17" wheels just wont hold up as well as similarly strong 16"s. Plus you get a better ride from 16s, and you can put cheaper rubber on them... aha... more cost cutting....and also to improve the ride, the suspension is usually softened...

The AVCS technology is expensive... another cost cutting idea. If Subaru makes a car go 0-60 under 6 seconds and can do that with the most minimal HP/TQ and technology possible... they know it will sell and they know they can keep it at a very competitive price point... thus making their wallets fatter.......

WRX is the term for the Rally inspired car they sell so they can race in the WRC. There is no Wagon in the WRC... but in the US, we are picky.... we play Gran Turismo and we like the WRX.... we would be less likely to buy the Wagon version (with nothing changed) without the letters WRX on the rear. The US WRX wagon is simply about marketting. For the same reason that Acura in Japan IS Honda... for the same reason that the Integra in Japan is STILL the Integra in Japan, not the RSX...

But most of all its about that magic number the accountants came up with that they told the powers who be at Subaru that the WRX will SELL at....thats why we get screwed!

as for the theory of the japanese and europeans wanting to keep their best cars in their land, then why do the UW manufacturers have car models over there that we don't have here... ford escort comes to mind...

Main issues are gas quality and emissions. there cars are also lighter because of crash regulations.

No car manufacturer wants to stop a model from being exported to another country. They all want to make money, and that comes though sales.

A lot of manufacturers don't even consider exporting to the US as the cost of modifying a vehicle to meet the extreme US regulations puts the price beyond what you guys will pay. If the regulations were more in line with the rest of the world I am sure you would see every overseas manufacturer unloading ship loads of really tasty cars.

Some questions - why are your regulations so tight? Are US drivers any worse than the rest of the world and need better protection? Or is it a case of trying to force you all to buy US made autos by creating a trade barrier? I have often wondered.

The STI numbers are limited for two reasons - specialised production line and to keep it 'special'. Keep supply just short of demand and they won't even have to discount (and they don't). Specialists like Ferrari recognised this many years ago.

This link gives a very good explanation of the JDM versions: http://www.iwoc.co.uk/jpnewage.html
