The Subaru 086A STI version featuring the next generation EJ25 - Toyota FT-86 Forums

admin · 10-13-2009, 04:56 AM

Although the highly anticipated FT-86 is going to be displayed by Toyota, development of the Subaru version is also well under way. Expect to see even more specs in the next 2 years!

The 086A sports car is being jointly developed by Toyota and Subaru, for some reason, it will not be displayed in the Subaru booth. Because the mechanical components including the engine and chassis were created by Subaru and the design by Toyota, Toyota was allowed to display the design concept only with Subaru's permission.

However, taking a deeper look reveals that the reality isn't so simple. Toyota actually has a significant influence in the mechanical components of this car as well. First, let's take a look at the engine. The car is equipped with the next generation EJ20, which, as mentioned before, uses the same direct port injection engine as the Toyota's D4-S. In addition, it is equipped with 6 speed transmission manufactured by Aisin.

On the other hand, Subaru uses this car as a base and improves its sportiness image and is working on creating a "STI version" on their own.
There are rumors that it might use a turbo, but taking factors such as the strength of the drivetrain are taken into consideration. Chances are that it will use the next generation 2.5L EJ25 instead. The maximum horsepower will be roughly 240HP-250HP compared to the normal 200HP.

The settings around the foot? will attempt to keep the basic characteristics of the car, but with additional tuning to increase the amount of (something)G generated. Of course, the tread and tire size will increase, and the fender shape will be changed accordingly as well.

The car will most likely be revealed at the next Tokyo Motor Show in 2011, or the Tokyo Auto Salon in 2012 just prior to its release. What kind of performance can we expect from this wide-tread, wide and low STI version? Our expectations are high!

The STI version will be equipped with a wide fender, a specialized front bumper and rear spoiler. Will it also succeed in the world of motor sports?

sweet. Doubt THIS one's gonna be in the $20k area....but still good stuff

If this does make it to production, I think I may have found my next car! As long as it's rwd and not awd!

It looks similar to the 86, beside the front bumper+ grill, wider kit and rear wing. Just can't wait for next 2 year...=.="

Wow. Color me impressed.

Not too shabby. I would prefer to own a Toyota rather than a Subaru (currently a Celica owner), however since they'll both basically be the same thing, I may have to wait the extra year and get the Subaru STI version of this sweet car!

I actually like this better than the Toyota version...which I guess is convenient considering the U.S. is suppose to not get the Toyota.

WTF is direct port injection.

like the exact same as regular port injection?

Why no AWD? I had an STI, and it sold me on AWD.

I could do amazingly freakishly tight doughnuts in that car, great drifts, and AWD launches are out of this world. Trust me, its good stuff when done right.

Second, where is this information coming from again?

In 1998, Toyota's D4 direct injection system first appeared on various Japanese market vehicles equipped with the SZ and NZ engines. Toyota later introduced its D4 system to European markets with the 1AZ-FSE engine found in the 2001 Avensis and US markets in 2005 with the 3GR-FSE engine found in the Lexus GS 300. Toyota's 2GR-FSE V6 uses a more advanced direct injection system, which combines both direct and indirect injection using two fuel injectors per cylinder, a traditional port fuel injector (low pressure) and a direct fuel injector (high pressure).

I understand that direct injection is supposed to make new strides in terms of efficiency and power. But what is it that makes direct injection so much "better" than port injection?
