I'm not quite sure how you inferred that, but no, that's not what I'm saying. I'm saying a simple search for "turbo compression ratio" provides a thread dedicated to what this guy intended to discuss, and just about everything else relevant to that topic. But instead he skipped the introduction thread, and went ahead and posted this.. in the wrong forum to boot. It's happened quite a bit since the massive leaks, and it's usually folks who joined right after that are guilty of this.

waiting for someone else to ask if it's a hatchback now

Is it a hatchback now?

It's Superchargers that whine. Turbo's whistle...:)


I will add that an N/A build, perhaps from Cosworth, on this would probably be tits... Would be to loud though for DD. A turbo quiets the exhaust note and still maintains power.

I'm thinking GT30R with Open Wastegates on this Boxer would be pretty Yummy...Fueling will need to be on point.

Bah...way to ruin my metaphor Dragon!

Why do you think this is funny? I like room for more power in case I get bored. Lets keep in mind that if we keep the high compression, we need a big enough turbo to make that 300whp at a low psi.

Cause you don't need a 57mm turbo to make 300whp. Because of the insanely high compression, you also would not need to run a lot of boost. I guess we'll see what is what soon enough though.

Like I said haha i know a 57mm is beyond 300whp lol, there are many factors though for me. I still want to retain good mpg when cruising =]

1. To me it's nothing, I've built a port injected, open deck motor with 11.5:1 static c/r and 11psi PSI on a supercharger, that was EASY to tune. With DI it'll be easier. I don't need to explain why I think a certain component can't handle it. I'm not trying to make you a believer.

2. Wasn't that I cared, but it was for the 2 member who mentioned Cobb, and I know they wont touch it unless it's factory boosted. I don't have hopes and dreams, I know what is coming, everything I've said in the beginning of the year has been true. My only gripe was that the base Subaru wasn't low output factory turbo to the high output in the STI variant because of the agreement.

3. It's a fact, the R56S MINI outperforms a Civic Si in almost every category. That's a 1.6L small twin-scroll turbo vs a high output K20xx(which you could say is like the FA20). Then add a $795 mod(ALTA/COBBAP) and it will demolish it in all categories, with that mod it also becomes a Lotus hunter, given they are both on the same tire.

I'll throw a tiny bit of support to the factory turbo guys.

From what I remember, officially all they've said is that it won't launch with a turbo.

Secondly, there was official talk about 'this motor was never intended to be turbo'd', but that was about the FB20, when everyone assumed this car would get a modded FB20. It's not.

So: A) they could turbo the FA20 at a later date (Yamaha has turbo car experience with the 3SGTE and 1JZGTE).

B) they could still put in a different turbo motor at a later date.

But I haven't been keeping up with the new WRX/STI motor rumour mill.

There will be definitely a BRZ Turbo (2.0 FB Engine)!
(information from a STI insider)

On initial launch or later down the road?

It won't happen until it's done! ;p

Subaru hasn't even made a turbo engine on the new design yet. That's at least 2013/2014 for the new WRX.

later :happy0180:

Official from a FHI engineer. The FB was not designed to accommodate future turbos.

Maybe they tweak the engine a bit.:iono:
Subaru did mention that there was no plan for turbo in this car, that doesn't mean they will not put a turbo in later down the road. I could be wrong though.

They said no turbo in the design for the FB series. But this isn't the FB series, now is it? There's still hope for some of these guys.

And the WRX/STI is likely getting its own non-FB motor as well.

They said no turbo at launch. So the future is open.

Ok, I gotcha.:respekt:

A fellow member here posted a video that Subaru is talking about up coming model. Subaru mentioned that WRX/STI model will have Turbo charged FB and and STI will have more than 300hp. I don't think Subaru is lying at the press release. :\

Here the vid:

I concur with this statement. But TBH it can be FA, FB, FC, FD doesn't matter what they stamp on it. The STI BRZ will be turbo, Subaru will always stay true to the enthusiast in the STI line.

I'm so glad you are wrong.
the WRX will have a 2.0 Turbo FB engine as announced
at the LA autoshow.

Source?

And since when did enthusiasts require turbos? I don't want a turbo in this car so I guess I'm not an enthusiast.

Precisely.

:bs:

+1 :word:

apparently STI is synonymous with turbocharging.

:word:
Not that non turbo people are not enthusiasts, but STI fans are turbo people.

Source? Oh wait...

heh...


Seriously though, with how butt-hurt Subaru has been acting with its 'We did it all!' press releases, I wouldn't be surprised if even if they use a turbo FA20, they would re-name it back to an FB20.

The bore and stroke will show how much the WRX/STI motors relate to the existing FB motors. I'm still curious about the 72mm stroke on existing bores idea that we were floating around long before we had the 86mm X 86mm confirmation.

Also some of Moto-P's old posts seem to indicate that the cars are not as conceptually attached to each other as they will appear on release. It could be a time/money-constraint thing.

I thought that the BRZ was being released with an FA engine...:iono:

It is.

Yes. This thread about turbos has to do with the real (WRX/STI and whatever they call their motor) and speculative (maybe BRZ a few years down the road, but currently only a confirmed NA FA20). So forgive the mixed up nature of engine-talk in this thread. (But it is still better than most on here... heh...)

I bet STS is gonna jump on both the FR-S & BRZ with their system:

http://www.ststurbo.com/

A rear mount setup could be interesting, but it tends to be better for higher displacement engines (the smallest engine they make a bolt on kit for is a 3.5 liter v6). Heat and exhaust volume are what spin that turbo, and exhaust gasses have cooled significantly by the time they get to the back of the car. Still, until we actually get to REALLY see how much room is available and where within the engine bay, it's anybodies guess.

I'd like to see somebody make a low pressure small turbo setup for this car with an air to water intercooler. One which places the water reservoir in the trunk, to help offset the added weight up front from the turbo.

These systems are horrible for low displacement engines. I've been in a few stealth turbo setups on Hondas based on this idea.. it's not all that great. I've also been in a Z28 with a setup like that and it worked fine.

I do not think the BRZ STI will need a turbo. It will need more power that can be achieved by more expensive technologies, ITB, larger displacement,... and lower weight than can be achieved by more exotic materials, CF roof, trunk, hood, roof, doors,....

Who wants a turbo can get a WRX or WRX STI, or swap the WRX/STI turbo/engine on the BRZ/STI.
I see it rather this way:

BRZ: NA 2.0l, 200 PS, RWD
BRZ STI: NA 2.5l, 250 PS, RWD
WRX: FI 1.6l, 250 PS, AWD
WRX: 2.0l, 300 PS, AWD

You would rather get lesser gains, AND spend MORE money to get less?

We're not discussing whether or not there will be factory turbo option on the FA20, and the whole "if you want a turbo get a wrx", they're completely different kinds of cars, your statement there is lacking logic.

The BRZ STI concept is shown to be powered by a NA 2.0l, where you're getting the 2.5l idea from, I have no idea. Beyond that, we don't know if Subaru will even make the STI variant or not.

Come on guys.

Turbo til it blows up then build low CR + E85 + turbo = perrfect.

I'd rather have the STI be NA 2.0L, bigger cams, more compression, higher redline (8500 :) ) and 240-250hp.

that sounds like so much win
