JDM Subaru WRX STi

[Adampops]

Okay, I am very new to Subaru's so if this question is really dumb just ignore it.

Didnt Subaru make a WRX, and a WRX STi in japan for the old body style (? - 99) i believe? I always thought they did. But in search for the WRX or WRX STi engine i cannot find any. Usually on ebay there are thousands of honda engine etc. But ive never seen an older model turbo WRX engine. Could sombody help me out here.

I don't know for sure, so don't quote me on this, but I don't think there's much difference between our engines and the WRX and WRX STi engines of previous years. The main differences are probably just a bigger turbo and forged internals...definitely not enough to warrant a whole new engine. After all, the engine code is still the same (EJ20).

I'm sure someone with more knowledge of previous WRXs can explain it better than me

That had "STICKY" all over it.

Great Info 206WRX_GDA...thanks for sharing.

[206WRX_GDA]

Those are the JDM/AUSDM/UKDM specs at least. I don't have info on the USDM stuff, but I didn't know if anyone cared about the Impreza L. Heh. Anyway, that was provided to me by Yosi at J-Garage....it's some good reading man!

You don't really KNOW your car, unless you KNOW the heritage behind it. My opinion.

I don;t claim to know very much about the WRX or even subaru...but i've come to enjoy learning all I can about the WRX, Sti, Imprezza, and Subaru in general. This is definitely good info for ANY WRX enthusiast.

[206WRX_GDA]

I totally agree with you. For me, when I read this brief history, it actually made me feel more appreciative of the car and the Impreza. I can't recall where I found this, but here's some more interesting history:

"Unlike some other motor companies, such as Ford (founded by Henry) or Suzuki (founded by Michio), Subaru is not named after its founder. "Subaru" is the Japanese word for "Seven Sisters", a common name for the most prominent stars in Pleiades, an open cluster of about 500 young stars (only about 100 million years old), barely visible in our northern sky. At least six of the 500 or so stars are visible to the naked eye, while under moderate conditions the number increases to 9, and under clear dark skies, jumps to more than a dozen. To see the rest, good quality binoculars or a telescope is required; but the cluster is still difficult to locate as it is spread over only 2 degrees - about four times the diameter of the moon.

The name "Pleiades" itself may have been derived from the Greek word for "to sail" or the word "pleios" meaning "full" or "many".

Another theory is that the cluster is named after the mythological mother, Pleione, which is also the name of one of the brighter stars. According to Greek mythology, the main, visible stars are named for the seven daughters of "father" Atlas and "mother" Pleione: Alcyone, Asterope (a double star), Electra, Maia. .Merope, Taygeta and Celaeno.

Although somewhat similar to the constellation Crusis, comprising Gacrux, Alpha 1 Crusis, Beta Crusis and a few other unnamed stars, which we know (in Australia) to be the Southern Cross, the Subaru badge represents a totally different group of stars.

But why does the Subaru badge only have six stars?

Ken Takeuchi from Japan has provided this insight, including an alternative background for the star emblem:

To say first, SUBARU may stand for "seven sisters" may be true but the Pleiades stars are also called "Mutsura-Boshi", which means "six gathered stars". The star SUBARU even appears in the lyrics written more than 1000 years ago. The word has some romantic feelings to we Japanese.

Fuji Heavy industries, the maker of SUBARU cars, was known as Nakajima Aircraft before WW II, which made many fighters and bombers. Even the famous Mitsubishi Zero fighter had a Nakajima 14 cylinder engine. After the war, the company was forced to spread into 15 companies to cut the strength of the huge weapon industry. But in the early 1950s, five of the companies gathered into one again to restart as a transportation company. That's FUJI and that's why there are five little stars and one big star.

So, the present SUBARU emblem represents the company structure rather than the original star cluster image.

Happy star-gazing."

Here's another intersting tidbit on the origin of the name:

Thanks for all the info. I never knew any of that stuff.

[FUNKED1]

FYI Nakajima supplied most of the fighters for the Imperial Japanese Army Air Force. The Ki-43 was the most common one, and it was generally similar to the Zero. They also made the Ki-44, which was a high performance interceptor, and the Ki-84, which was as good as anything in the Allied arsenal late in the war, even the P-51 Mustang. They had production problems due to aerial bombing and naval blockades, but these aircraft were all brilliantly engineered. Quite a heritage for Subaru!

Aren't the JDM specs a little better than the Aussie and UK versions?

[206WRX_GDA]

The hp/specs on the ADM and UKDM are about 30-40 hp less than the JDM versions. At least for the GC8s. I'm not sure what the specs are for the GDB/GDA...

[Adampops]

Wait, im still a little confused. So is the GC8 WRX engine the same as our 2002+ USDM Engine?? And are they any websites of places that sell used JDM WRX STi engines for the GC8. And what is the engine code and chasis code for the USDM 2002+ WRX?? Sorry, Im trying to get all of my subaru history down.

[206WRX_GDA]

Chassis Code-Description

GC8-The Original Body Style Sedan
GF8-The Original Body Style Sport Wagon
GDA-The "New Age" WRX Sedan
GDB-The "New Age" WRX STi Sedan
GGA-The "New Age" WRX Sport Wagon
GGB-The "New Age" WRX STi Sport Wagon

Not sure how to answer your question. There's a few different engines for the GC8 WRX. As for the USDM WRX, the engine code is EJ20, chassis being "GDA", hence my screen name. Heh. There's plenty of places that can get STi engines for the GC8. IF you are interested, there's actually a shop in Bellevue, WA that's putting in a STi VII engine in a '97 GC8 coupe. Just do a search online, or email some Australian shops. Shipping should be easier and cheaper from there...

Awesome info! Agreed that some posts in this thread need to be in a FAQ and/or sticky...
