what's the difference between both cars ?

WRX - 2.0 turbo 227 hp
STI - 2.5 turbo 300 hp

There are differences in the exterior and interior trims between the cars too.

Those are the figures for the North American models, the WRX and STI available in other countries have different figures.

ah cool, and the Sti have 6 speed instead of 5 right ?

Yes. All new STi's come with 6-speed and WRX's with 5-speed (apparently too much torque to need a 6th gear :evillol:...however, I wouldn't mind a 6th for cruising in on the highways)

No offence, but as freakray suggested in the other thread, try looking at the manufacturer's website first since they offer answers to all your basic questions.

Plus the STi has a *much* better suspension package, a Driver Controlled Center Differential option, front limited-slip, rear-wheel bias AWD, better wheels, better tires, a better aero package, etc. STi = WRX, but with everything better.

...rear-wheel bias AWD,...I thought all AWD Subarus were RWD-biased. Even if only nominally...

I thought all AWD Subarus were RWD-biased. Even if only nominally...

Other way around.

They're FWD biased, the auto is more biased than the manual.

Excepting, of course, the STi

Excepting, of course, the STi

That could be explained by the fact that the driver controls the bias, not the car's computer.

Even on "auto", it's still rear-biased in the STi.

The STi is 35/65 on auto, and can be adjusted all the way to 50/50. I have no clue about the WRX.

I just got the Impreza book a few weeks ago (Counting the days......), I will look and see if it has any specifics.

It's all on Subaru's website (or it was when I was buying one...)

this figures is only for North America version. The other version is:
WRX - 2.0 turbo 250 hp
WRX STI - 2.0 turbo 280 hp <--much lower than the North American one.... :loser:
and i think the australia version's WRX STI only got 250hp (i heard it from somewhere else) correct me if i am wrong

Basically, the WRX STi is faster, more powerful and has better traction ability than the original WRX. It has a front mount intercooler (instead of the puny top mount one in the WRX), a bigger turbo system and boasts about 224 KW of power compared to only 169 KW with the WRX (Australian figures). In terms of appearance, it has a larger rear wing, larger roof scoop, STi fog lamp covers and bodykit.

errr :eek7: not quite.

You're talking about a larger HOOD scoop, because of a larger TOP mount intercooler.

Yeah but our STi is still 2L compared with the American 2.5L which breaks WRC rules so......:loser:..........J/K :iceslolan

I hear we're gonna be missing out on the 2.5L WRX as well.

It has a front mount intercooler

You better let Subaru know you've changed where they mount the intercooler so they can change it on the assembly line....

...oh never mind, you don't know what you're talking about. :rolleyes:

You said:

In reply to my post which stated:

STI - 2.5 turbo 300 hp

Now what is wrong with your post?

It has a front mount intercooler ...

...In terms of appearance, it has a larger rear wing, larger roof scoop, STi fog lamp covers and bodykit.

*frantically runs outside to look at car*

Nope, it still has a larger than WRX top mount intercooler just under the larger than WRX hood scoop

Also, I can't find the roof scoop on my car. Do you have suggestions as to where I might find it, or part numbers so I can somplain to the Subaru dealer I bought my car from?

Does that mate from down under not know what a hell he is talking about?? Or do those down under STI's really have frount-mounted intercoolers and "roof scoop", and "body kits"?? Body kits?? The only differences I know of eternally are wing, fog lamp cover, larger hood scoop....anything else??

better performance :/

Does that mate from down under not know what a hell he is talking about??

Right first time :smokin:

Maybe he should bring himself up to speed....

If I plan to mod it, it is better to buy the WRX ? or again the STi is better ? ( i'm talking about performance )

You better let Subaru know you've changed where they mount the intercooler so they can change it on the assembly line....

...oh never mind, you don't know what you're talking about. :rolleyes:

haha ray's always mean to the newbies

haha ray's always mean to the newbies

No he's not, just the ones that make stupid statements :redface:

Well, you'd be surprised at the number of WRXs and STi's running around here with front mount conversions. I'd say 35% of all modified WRXs have a front mount conversion. I think the dude is just confused.

So tell me... are FMIC's a whole lot better in perfomance than TMIC's given identical intercoolers??

I guess you have to take in account the size of the hood scoop and avoiding junk from sticking to the IC when mounted on top, and it may not be a straightforward comparison...

FMIC and TMIC have their adv and disadv. But comparing them just by their size, the front mount will always give you better cooling. I don't care how big your hood scoop is, but air coming directly at the IC is always gonna cool it better.

I have seen a few WRXs set up for drag, and not one has a TMIC. I'm not saying they don't exist, but for maximum power gains, FM is the way to go.

The only reason subaru elected to put it on the top in their WRC cars is so they cars can continue racing after minor front end collisions. If there was some crazy rule introduced about how any front end dammage would result in disqualification, I would think subaru would stop with their TMIC.

Personally, I would want a FMIC cos the hood scoop attracts a lot of unnecessary attention from police and ricers.

Are you sure that the WRC car doesn't have a FMIC?? It looks to me like it does from the outside, or perhaps it's got one big ass radiator.

Thw WRC car doesn't have a TMIC, it's a FMIC and it's mounted at an angle directly above the radiator, the oil cooler is mounted to the left of the engine bay.
Here's a top view of the 2005 engine clearly showing the intercooler mounted to the front:

And here's a photo of the 2004 engine with the shroud over the intercooler, which is clearly a FWIC;
http://www.swrt.com/cpimages/488512.jpg

As to the benefits of TMIC versus FMIC, with a FMIC you can mount a bigger intercooler but with the engine configuration of the Impreza this serves no benefit since you then have to have 3' of large diameter pipe from one end of the HOT engine bay to the other. The reason Subaru opt for the TMIC is the efficiency gains, with the TMIC the air flow has a minimum amount of distance required to travel from turbo to intercooler and then to intake manifold allowing for maximum air flow efficiency.
On the WRC cars the turbo is relocated to reduce the amount of plumbing needed through the engine as well as using a spray to keep the intercooler temp down.

It's kind of scary, but I see a lot of ignorance displayed on the part of Subaru 'enthusiasts' about how the design of their cars originated or even the function of the design.

I see....

But I swear I remember hearing about how subaru "has saved many a race by mounting their intercooler on top to continue racing after a minor crash"

Have they never had it TMIC?? Or as you say that the turbo has been relocated to reduce plumbing (which means, i guess, turbo lag), then isn't it more like a hybrid that gets best of both world? i.e. less lag AND more airflow. Which are adv of TMIC and FMIC, respectively.

But yeah...I was quite surprised since my screensaver came up and I went, hold on, that looks like a FMIC...whoah! lol

Subaru hasn't used a TMIC in WRC competition since 1997, which is also the year that the WRC was officially created.
The group N cars still use a TMIC because regulations require it.

AHH!! Thanks freakray! It's the Group N ones! For a minute there I was wondering if I was more of a newb than i already am.

Well, even the WRC's intercooler is sort of top-mounted. It's set up like a FMIC, with air flowing directly through the nose of the car into the fins, but it's mounted at an angle atop the engine bay. So, it's at the front and on top, but not under the hood scoop. It functions as a front-mounted intercooler, but physically sits on top.

Fimc? Timc ?

Top/Front Mounted InterCooler

ohh thanks :)

Actually, the WRX STi does have a top mount intercooler (but a bigger one). Its just that I saw heaps on the roads of Sydney with front mount ones (there is so many that it leads you to believe that it is actually front mount). Regardless, I don't understand why they would have one like that. They should just have a front mount one and it looks way more hardcore...

A little bit off topic...Can you guys get EVOs in the US? I am pretty sure that we have to import in Australia. What is the price difference between a WRX STi and EVO and which is better in terms of performance and appearance (I personally think that the EVO is better just looking at the newspaper articles and comments by critics)?

The Evo vs STi thing has been covered many a times here. Try searching.

As for importing to Australia, the Evo 9 will be a production model here. They say it will be Jap spec, but most likely we'll get some faggy detuned version.

As for seeing lots of STi's in Sydney with FMIC, most likely you saw a WRX with a conversion, STi fog light covers and STi wing. Most ppl owning STi's here believe the turbo lag to be bad enough without making it worse by dropping in a FMIC. However, there are many WRX's with FMIC conversions and is what you probably saw. I'm not trying to be condescending, but just pointing out there is a huge "let's turn my WRX into an STi with $xxxx worth of mods" culture going on.

The STI does not come with a front mount from the factory, it still comes with a top mount, it is a little bigger then the WRX, but its still a top mount. You can buy a after market front mount intercooler to put on.

i thought wrx's are 50/50?

haha i just read this thread all the way through... some of yall really get off on calling somone out huh.:) funny though

Hey! The USA Subaru STI has a top mounted intercooler not front mount. Thought they all had top mount intercoolers. Perhaps I'm wrong

They all do. Straight from the factory, both the WRX and STi have top mount intercoolers.

Basically, the WRX STi is faster, more powerful and has better traction ability than the original WRX. It has a front mount intercooler (instead of the puny top mount one in the WRX), a bigger turbo system and boasts about 224 KW of power compared to only 169 KW with the WRX (Australian figures). In terms of appearance, it has a larger rear wing, larger roof scoop, STi fog lamp covers and bodykit.


:sly: the american sti does have a top mount intercooler. i dont know about any other countries though.
