BRZ STi NA 220-230 hp Rumors

[MrMuzace]

Auto Express UK has updated rumours on the STi BRZ and postulates the NA engine will output between 220 and 230 hp
http://www.autoexpress.co.uk/subaru/...bhp-subaru-brz

The heat is on for the Subaru BRZ, with a production version of the STi concept due next year

The Subaru BRZ is set to get a power and performance upgrade. A BRZ STi concept debuted at last year’s Los Angeles Motor Show, where global marketing manager Atoshi Atake told us: “We can develop the [engine’s] intake system; there is certainly room for improvement there.”

There’s also expected to be a freer-flowing exhaust to improve the sound of the engine, the variable valve control system is set to be tweaked and Subaru is likely to raise the rev limit past 7,500rpm. The modifications should raise power from 197bhp in the standard car to somewhere between 220bhp and 230bhp.

To complement the tweaks, Subaru will follow Toyota by upgrading the springs and dampers, and fitting 18-inch alloys with wider, grippier tyres and four-piston STi brakes. The changes are being evaluated at Germany’s Nurburgring track.

Unlike the rally-bred Subaru WRX STi, the BRZ STi won’t be turbocharged. Space constraints, particularly in the engine bay – which is too small to fit an intercooler – rule this out.

Four-wheel drive has been ditched for packaging reasons, while a supercharger is proving a problem as it would hamper the car’s efficiency severely.

Visual upgrades to the STi will include a modified grille, a huge rear wing, special side skirts and a front lip spoiler. And inside are extra dials and more supportive bucket seats.

One source close to Subaru in Japan told us to expect the BRZ STi to hit dealers there in the spring, and arrive in the US and Europe soon after that. It’s set to cost around £2,000 more than the £24,995 entry-level BRZ.

Hope it is changes in the internal of the engine, not some added on intake

Interesting level of detail. Seems "reasonable" and logical considering the overall previous message and direction from Subaru sources.

That said, I don't like that the article doesn't directly cite a source....(cough)

This might be no more than the author grabbing at straws interpreting the N-ring photos and guessing the STI is coming next spring.

Of course, it'd be nice if it was.

Rumors, rumors rumors.... One week its this thing, on week its another..
There are several rumors that back up this rumor tough. So who knows. Maybe we never will see a turbocharged BRZ (STI). But what about all the rumors about a turbocharged model... Back and forth..

20hp lol

On a car this weight, even 20hp isn't insubstantial. Assuming a weight of 2762 lbs, 20-30hp should be good to knock roughly 0.4-0.6 sec off the 0-60 mph time.

Rumor threads suck.

[swift996]

I called this some time ago and will continue to believe the STI version will be about a 20hp bump, better tuned suspension, brakes, wheels, and some aero additions. I'm guessing it will run about $34-35k.

Crap! Raising the rev limiter means less torque.
Why can they place the turbo like AVO did?!
That "doesn"t fit" crap is retarded!

Oh please! 20 hp unless its at the wheels is crap!
You'll see a bunch of threads of people racing the STI version
Against the regular BRZ and having even races.
Big wheels, big wing, big brakes, body kit...
All this crap throws away the gained 20hp.

Just like the nismo version of the 370z, all the normal Z's
Outrun the Nismo.

For one, this is silly. So, 20hp is bad, but 20whp is ok? You realize that you're talking about a 6hp difference between those two numbers, right?

Add 20hp, subtract 150 lb in weight, equals awesome.

But let's be honest, this article is crap without sources. I refuse to click

[whtchocla7e]

No way the STi is gonna be lighter, lol.

why internals? they are forged from factory... actually fracture forged rods and billet drilled forged crank as well as we get super advanced Sodium filled vales in the FA20. to be honest from a mechanical stand point this engine is extremely advanced. and is strong as nails.

[ngabdala]

Alot of that article has the exact same sentences from the bullshit rumor articles .

I'll believe it when it's announced by Subaru

And the STI is rated to actually weigh LESS... soo with different weight, more power, and better wheel sizes, maybe 1 sec faster

That was the only thing that kept me coming back when the car was being tested. I would check twice - three times a day for nuggets like these.



It builds hype

[Captain Insano]

If it has 230+ hp and loses 125+ lbs.... plus the brakes aero and suspension tweaks it could be pretty good.

[Metabrz]

At first I was like: fuck!! I havent even got my regular BRZ yet.

Then I was like: cool, I'll just trade my BRZ in for the STi when it arrives.

Now I'm like: only if they don't make the BRZ STi like the new Legacy STi.

Subaru has a lot of face to save by putting out a kick butt STi version. I have a hard time seeing them come out with a shitter but you never know.

While the cabriolet is yet to be officially declared, the chief engineer of Toyota’s sports cars, Tetsuya Tada, did confirm that a performance version of the GT86 was in the works.

But rather than using forced induction, the honed GT86 is likely to use hybrid drive to provide extra boost without impacting economy. Tada said a GT86 performance hybrid with around 250bhp was in development in Japan, with an on-sale date of 2015 mooted.

Hey look! A rumor with a source. Now we're talking. (Yes I know this is the Toyota and not STi.)

This would be ideal! But given the size & weight of modern cars, I don't see how Subaru can drop that much weight on a production car. It's a shame that the BRZ weighs as much as it does. I guess it's "relatively light" (by today's standards ).

To meet today's safety standards/expectations, sound expectations, comfort expectations the cars are just going to be heavier.

Imagine if Subaru/Toyota made a car that was super light? Two air bags, super cheap radio with 2 speakers, no sound deadening.

About 5% of their market would want to buy it. They make these types of cars in the UK and they are all expensive and rare. A true lightweight car from a major company that isn't expensive just ins't going to happen anymore.

[ngabdala]

Agreed. The 2011 Honda Civic Si I got rid of for my BRZ only weighed between 2800-2900lbs. Not much heavier than the BRZ.

I wonder what it is on the BRZ that accounts for the mere 100lbs less than the Si?
