Please take note ONLY on what is quoted from Subaru's marketing manager Atoshi Atake:
Quote:
"We have already had many requests from interested customers regarding a faster version. Let me say this - we will certainly satisfy our customers. We are already working on a faster version."
"We can definitely develop the intake system"
"There is certainly room for improvement there."
"Plus, we want to keep turbocharging separate. It is for models like the WRX STI"
"The same goes for four-wheel drive. We could not make the BRZ four-wheel drive even if we wanted to."

So, it seems fair to assume that Subaru won't be turbocharging the BRZ because
they don't want to!
Then we have Autoexpress' own interpretation without any 'official' quotes:
Quote:
It is likely to produce around 250bhp.
In addition, there is likely to be a freer-flowing exhaust and modifications to the engine's variable valve control system, along with an even higher rev limit of around 7,500rpm.
Subaru says that it will not turbocharge the engine as there is no space at the front of the engine bay for an intercooler.
He also said that supercharging had been dismissed because it would make the BRZ too heavy on fuel.

And, it's those last two sentences that I would like to address...

Subaru don't use FMICs, they NORMALLY use TMICs with their characteristic hood scoop instead, so why would they care about the space at the front of the engine for an intercooler?! Additionally, the picture you've just posted
shows a supercharged Toyobaru with a FMIC.
Nice sound BTW:

Well, compared to turbocharging the supercharged 2010 Audi S4 3.0 TFSI (quattro AWD) tells us otherwise.
We can compare my BMW 1M twin-turbo to the supercharged Audi S4 (6-speed manual):
Engine Output:
1M................................................ ....... S4
335hp @ 5900 RPM................................ 333hp @ 5500-7000 RPM
332 lb-ft.* @ 1500-4500 RPM.................. 325 lb-ft. @ 2900-5300 RPM
*An additional 37 lb-ft of temporary torque is delivered with the standard turbo boost function.
Unladen Weight:
1M.................. S4
3362 lbs........... 3847 lbs
Fuel Economy:
1M.................. S4
19 MPG............. 18 MPG (city)
26 MPG............. 27 MPG (highway)
Ok, my 1M managed an average of 14 MPG for a complete gas tank as its best with the help of the cruise control (set to 112mph) and the M button OFF only in highways!
Back to the comparison...
Gear ratios: 1M.................. S4
1st............ 4.11............... 3.667
2nd........... 2.315.............. 2.158
3rd........... 1.542............... 1.520
4th........... 1.179............... 1.133
5th........... 1.000............... 0.919
6th........... 0.846............... 0.778
Final drive 3.154............... 3.682
Both engines deliver practically the same power output from a 3.0L 6-cylinder engine and despite the Audi's weight disadvantage (485 lbs.), the additional friction losses of the AWD system and a significantly shorter final drive ratio it manages to achieve
the same fuel mileage as the 1M!!!
