Autoblog JDM Impreza WRX STI Spec C

Could this be what Subaru needs to run against the Evo here in the US? Could it be enough to separate it from the 09 WRX? I think that some of the mods are a bit extreme like the thinner glass, lightweight battery, and lack of spare tire but if it comes with the aluminum hood, 070 tires, upgraded turbo/ecu, and appropriate suspension changes, it will be able to hold its own against the Evo. Recaro seats and smart key wouldn't hurt either.



From Autoblog:

If you're one of the many enthusiasts on this side of the ocean who pine for a choice crop of hot hatches that never make it to the States, we've got some bad news for you: the Subaru Impreza STI Spec C -- a limited run of 900 units packing an assortment of enhancements to give it the edge over the stock versions -- is finally going on sale in Japan.

For starters, the whiz kids over at Subaru Tecnica International have reprogrammed the ECU and fitted smoother ball bearings for the turbocharger to boost output to 304 horsepower and 311 lb-ft of torque. They've also retuned the suspension, reinforced the chassis, recalibrated the power steering's lubrication, fitted new rims on Bridgestone Potena RS070 rubber and reduced the curb weight with lighter body panels, windows, battery and tire kit. You can check out the images in the gallery below and all the details in the press release after the jump, but sadly that's about as close as you're likely to get without boarding a flight to Tokyo.

SUBARU PRESS RELEASE

FHI to introduce the Subaru Impreza WRX STI spec C

Tokyo, July 23, 2009 - Fuji Heavy Industries Ltd. (FHI), the maker of Subaru automobiles, today launches the "Subaru Impreza WRX STI spec C", a new addition to the current WRX STI line-up. The model goes on sale today through Subaru dealerships in Japan.

Based on the Impreza WRX STI, the iconic sport model of Subaru, the WRX STI spec C model features enhanced engine and chassis performance as well as a lighter body on the premise of driving in motor sports. The model further strengthens its presence in the high performance car arena by offering sheer excitement and unique driving sensations as a distinctive road sport model, in line with the performance level originally delivered by the Impreza WRX STI.

The turbocharger newly adopted ball bearings for the turbine axle bearing, and the ECU (Engine Control Unit) program was also exclusively tuned. Thus the engine of the spec C model provides quicker response and improved accelerating performance. Thanks to its specially designed front & rear suspensions and improved body rigidity, the chassis offers stable and linear driving control even in marginal driving conditions. The adoption of an aluminum engine hood, laminar window glasses and a downsized battery resulted in a lighter body, which further polishes the model's driving performance.

Subaru enhanced the WRX STI line-up by introducing this STI spec C model, in addition to the STI A-Line model, the AT version introduced in February this year.


Outline of Subaru Impreza WRX STI Spec C

Enhancement of Engine performance:

•• Ball bearings of the turbine axle were newly adopted to reduce friction in the turbocharger. With the optimized ECU programming, the engine offers smoother and quicker response to the accelerator pedal and excellent accelerating performance.
•• An inter-cooler water spray prevents rise in intake-air temperature at continued high-load driving, providing stable engine performance and improved efficiency.

Enhancement of Chassis performance:

•• Reinforcement of the cross member in front-suspensions offers a linear steering response.
•• Specification changes in damping force of suspensions, coil spring rate, rear stabilizer and rear sub-frame bushes optimize rigidity for body roll and retain excellent road-holding capability.
•• Rear LSD (Limited Slip Differential) system was changed to a mechanical type from a Torsen type to obtain the steady and powerful traction during cornering.
•• Bridgestone "POTENZA RE070" (245/40R18) were adopted to enhance cornering ability and higher grip performance, especially in dry conditions.
•• Nimble handling with a firm steering feel is assured by increasing oil flow volume in the power steering system.

Lightened body:

•• An aluminum engine hood and a downsized battery, which make the front section of the vehicle lighter, produce better maneuverability.
•• Laminar glasses were adopted in the front and side windows. They lightened the upper section of the body weight, resulting in improved stability during cornering.
•• Newly-designed lightweight 18-inches alloy wheels are standard to offer excellent road-hugging property by reducing unsprung weight. (17-inches alloy wheels are optional)
•• A flat tire repair kit is standard, which also helps weight reduction.

Others:

•• A structural change of fuel pomp provides stable fuel delivery even on high-load driving.
•• Gold colored "brembo" brake calipers are standard.
•• The front bucket seats (fabric with red stitch) are standard on models with 18-inches alloy wheels.
•• The "RECARO" seats (Alcantara and leather combination with red stitch) are optional on models with 18-inches alloy wheels.
•• Two exclusive exterior colors are available; Sunrise Yellow and Pure White.
•• The production is limited to 900 units.

Major specifications:

-Engine type: Horizontally-Opposed 4-cylinder DOHC 16-valve turbocharged engine

-Displacement: 1,994 cc

-Maximum output: 227kW (308 PS)/6,400 rpm

-Maximum torque: 422 Nm (43.0 kgf·m)/4,400 rpm

-Turbo type: Ball-bearing type twin scroll turbocharger

Spec C's were made for every single version since the GDB chassis from the WRX Type-RA STI. Most likely nothing to do with USDM 2010 STI's. The motor is completely different from USDM models anyway.

It's basically a 'race-ready' version of the STI being lighter and suspension improvements as a general upgrade. It's been like that for YEARS.

 

:sigh:





























:drool:

 

If that is the case then there is likely no hope for the 2010 STI to be competitive in the US (in its stock form).

I've been under the impression that the USDM STi, GDBs at least, was more of a Spec C than a regular STi. Perhaps times have changed.

 

From the initial USDM STI's(MY04) the part numbers were the same as the Spec C JDM STI's except for two things, the engine and the steering rack. Two very big things that the Spec C had a huge advantage over. Even to this day, I still believe the EJ207 to be much more superior. These two things were what made the biggest differences between the Evo and STI.

Later in the GD body line, the the USDM STI no longer had the same control arms as the Spec C. I believe this was for the last GD production year.

Which brings back to the MY10 ones. Is it likely that Subaru will bring the EJ207 that's used in the JDM Spec C? Most likely not, hence why I said it's not a good indicator of the MY10 USDM STI changes. The MY10 JDM Spec C most likely will not be the MY10 USDM STI, but as the past shows, alot of the parts may become the USDM STI version.

 

That yellow STi in the back is mine!

 

I'll take 2 of the yellow.

 

we will never see the Spec C in the US. the closest we will ever get is a STI limited. also the Ej207 is just a dream for us, we got the EJ257 because the EJ207 will never pass the tough Cali emissions without de-tuning it. de-tuning equals less HP/TQ, that is why we got the the EJ257 to equal things out.

 

2010 changes look rather minimal (black alcantara and red stitch). Pretty disappointing but at least 08 STI resale values won't be affected like the 08 WRX's.

i want an awd badge now

 

i was really looking forward to impreza's 2 year model replacement...am i the only one that still dislikes 08/09?

 

just curious, were the 04-07s built with the same frame/body? From a n00bs perspective it always seemed like head light and body kit updates.

 

Yeah, in fact 02-07 uses the same frame and a lot of common components.

 

Whuddup ol' skool! Nice to know you're still lurking.

 

Now Kidding Diego!! Wattup Brandy! Are you still driving the Green Leggy with WRX wheels?? Seen it at Ala Moana one time on the second level next to sears. Take care and hope you can make it out to the AUW and bring your USDM STi bugeye!!
