The Subaru believe or not looks just as good as any of those cars, only the Ferrari and SLS really show it up. Ok and maybe the Aston..or maybe its the color of the subie that I like so much.

Have there been any mods to the FA20 engine released that were not turboed or supergharged?

WingsofWar said:Today, I was on the phone with a friend in Japan who is one that is head over heels about the GT86. While Subaru and Toyota information leeks have stopped...... for now... There has been some idle talk in the JP BRZ/86 community about the upcoming models. (Remember these are only predictions and rumors from the land of the rising sun)
1 of which is the changes that are being made to the FA20...particularly FA201.
+Some have been concerned about the mid range dip found on the BRZ torqeband, spawning many different theories with no real conclusive explanation. Intake acoustics have been found to have the greatest effect on this...
Subaru's solution for next year is to adopt TGV into next years model lineup.
In order to make the vertical vortex (tumble) gas into the combustion chamber and intake from the intake manifold, intake port with a septum and TGV (tumble generator valve federated), oriented tumble intake port has been adopted.
TGV is a valve for generating a tumble actively in the low-speed range, close the valve, the easier it is to raise the tumble of the intake air, raising the combustion efficiency and to increase the gas flow.
Intake port with a septum is divided into two parts by a partition wall passage, which leads to tumble intake port as it is oriented.
There are also separate parts by a partition wall tumble intake port-oriented, in the low-speed range while increasing the flow rate leads to a state to pass through the passage of the outer gas engine, easy to make the tumble. At high speed TGV is the is open, and uses the entire intake port.
The state had created an intake easy, pass-through in the intake port tumble. The tumble is sent into the combustion chamber, creating a vortex to fit the shape of the piston head cavity DIs head of the piston cavity center.

+Water-cooled EGR with a collector..might also be adopted into the FA201.

+Talks of Denso being switched out next year in favor of Hitachi DI injection drivers ECU and Hitachi injectors with a dual spray pattern.

While many of these things have already made its way into the current Legacy GT DIT Featuring a DI only FA20 Twin Scroll Turbo, I don't hear anything about the actual turbo itself being implemented into the BRZ platform. So we are still less likely to see this under our hoods from the factory.

So what can we expect? More power? No I don't believe so. but i do expect plenty of improvements in our current power band output, and economy. It is unclear if the Toyota/Scion twin will also be having next year's changes, but given their contract and also being built at the same plant...the odds are very high that Toyota/Scion will also have these changes as well.
