Report: BRZ STI Model Already in the Works, No Turbocharger

No turbocharger:

So the same things that the aftermarket community will end up doing and I don't have to wait 2 years. Either way it's fine with me.

So glad they are not going the force induction rout!

250 NA with a slight weight reduction would be perfect for my intended purposes...

hope they release it next year and not at the mid-cycle refresh.

Sweet, I was hoping to hear something like this. That means almost all of that power can be accomplished in the aftermarket. I knew there was some N/A potential left in this motor without building it. Means we should get some nice gains from a good intake and exhaust.

Don't get your hopes up. To eek out another 50hp on this motor would likely entail more aggressive variable timing, tuning, higher redline, and probably boring out the motor.

I/H/E/tune on a 2.0L, you might, might get 20hp tops. but dont count on it. The car is pretty well optimized at 200, any gains will be expensive and require mods that are generally best done by the factory.

I would be very surprised if they released this version next year. We'll see.

There is no reason for them to rush this. The current spec car is selling like hot cakes in Japan and is about to in the rest of the world.

It's crazy that they're leaking this info this early before the base model is released! Won't have to wait as long as I expected. No FI means less rapid heating/cooling (reliability)... always good for the head gaskets.

this makes me happy

It makes much more sense, BRZ is the NA, lightweight, rwd coupe and the WRX will be the awd turbo monster

This would almost make it a Cayman. And I'm sure, as much as I'd like one, it'd be too expensive for me. At least the cost of an WRX STI.

I've had a hunch from the beginning though and looking at the dynos so far, that there is some breathing room up top. I think (and hope) we'll be surprised on what a few mods and a tune will do.

The fact that all of these people in official capacity for Subaru are already talking about higher performance versions, coupled with Toyota saying they want to release a different variant every year, makes me also believe this "BRZ STi" will show up sooner rather than later.

YYYEEEESSSSSSS!!!!!!!!!!!!!!!

Guys, the +50 hp was never quoted from Subaru. The editor who wrote the article probably put that figure in as his own opinion/speculation.

Same. This almost makes me want to wait. Maybe it'll be released in May 1st, 2014 and we'll find out the price of it April 30th, 2014. :)

Awwwe......

True....BUT, in the autoblog article they asked Toshio Masuda the BRZ senior project manager:

"I asked Masuda-san point-blank if indeed there will be an STI-style turbocharged BRZ by the time this generation reaches the middle of its life in two-and-a-half or three years. A number came out of his mouth that raised my eyebrows. "In future, there is the thought to have as much as 280 horsepower."


So the 250hp is possible and maybe Atake is being conservative. How they get to that HP is still up in the air though.

250NA HP with STI performance stuff and look! :wub:
Awesome news!

Doesn't seem like the best idea to be leaking this now, I agree. If they come out with anything resembling a release date for it, I'm pulling my deposit and holding out for the STi model... I just hope I can still put a supercharger on it if they bump up the power while still keeping it N/A. I guess they couldn't increase C/R much more than they already have.

The FA20 can be engineered to attain +50 or +80 HP if you let engineers have at it without reserve (extreme case of a car without compromise: MP4-12C). +50 NA HP would be awesome but also awesomely expensive. As a massed-produced car, they also have to consider cost, reliability, fuel efficiency, etc. and dial back a bit. Probably the most direct way to achieve this starts by increasing displacement.

I'm kinda glad they're not turbocharging it. I like how they're sticking to the original theme of the BRZ.

I'm interested in how the "dramatic" body kit will look.

I hope they use a damn 2.5 for this one.

I have to see it to believe it

I agree.

the concept car was not dramatic. probably similar to that... IMO tastefully done w/ exception of the wing.

I'm not expecting 50 hp from intake and exhaust alone, but if he says himself that there is definitely room for improvement on the intake and exhaust, then that means they didn't even attempt to maximize it's power output. +20 more hp for these mods, plus the lighter weight of an aftermarket exhaust (the stock one is pretty heavy) I think will do a lot for this car.

that's all i need to know. whatever he says is probably PR bullshite...

Getting an extra 50HP out of this will be easy - especially considering the high C/R and the presence of direct injection. Here's some food for thought - consider the first generation Honda S2000, in the states it produced 240hp at the crank, in Japan it was 250hp. In the Honda community people were able to increase this number with simple bolt-ons, increase C/R, and minor tuning. Shit, there was even a company that improved the air flow CFM on the intake and exhaust porting on the head. All of this out of a 2-liter engine who's compression ratio was lower and lacked direct injection. If you think Subaru has to increase displacement to realistically achieve a goal of production @ 250hp, then their R&D department doesn't know shit about building NA engines. I really doubt they'll increase displacement. To be honest, chances are increasing displacement would cost even more in terms of R&D. Atoshi Atake was quoted stating that they (Subaru) are looking specifically at the intake system for the gains. This resonates perfectly to me when looking at the dyno sheet for the outgoing model. It looks like there is PLENTY of room for improvement in high rpm breathing, those stock cams look incredibly conservative - adding 50 more hp is a no brainer.

Hopefully if the BRZ STi come out, some of the parts will be transferable to the BRZ. Parts like the lightweight hood, probably not the roof since it'd be more than just the skin and that'd include cutting structural beams, brakes, and exhaust.

But yeah, at least then we would be able to have a lighter-weight version of the current BRZ.

W-A-I-T-I-N-G!! :popcorn:

The look-at-me carbon fiber hood would be a deal breaker for me. Sounds pretty cool though.

Exactly! Already we get an aluminium hood and although a carbon fiber roof will be nice, a CF hood will only make it more expensive. As already told by someone else, in the range of WRX STi will be a deal breaker for me too. Enough of this waiting! They will bring better but expensive versions every year and then if i can afford a better one then, i will get, otherwise will be content with current car i'm getting this year itself!
Look at the 2012 Nissan GTR, 7K USD more, for not really much of more equipment or improvement

Anyone else notice the "250" horsepower figure was not actually inside a direct quote?

Between this "article" and the USA Today "article" that confirmed turbocharging, I'm tired of these reports borderline just making things up for page views or whatever.

Also the racing bucket seats and carbon fiber roof/hood lines were not in direct quotes either - they are probably just guessing from the STI concept a while back.

Revised intake and free flowing exhaust sounds good on paper, but that also makes me worried about whether the US market would even get that model with emissions and all.

It's all just rumors still. There are just as many other reviews out where they spoke to someone at Subaru who said they are going to turbo charge it.

I find it hard to believe that they can squeeze an extra 50 hp out of the current engine. If they do I can't see it being cost effective, especially when they will have a turbo FA20 sitting on the shelf which will make the same or more power. That is a lot of development cost on another engine for a car that they will sell very few of. If/when an STI version comes out, it will account for what ~15-20% of BRZ sales? It is already a low production car so you are going to be talking about less than 2000 cars a year.

Yes this is exactly what I would have preferred! Thank you Subi!

Anyone know what kind of weight to hp this car would have compared to other cars?

++++++++++


What's even more perfect?

33-35mpg.

Lol

LOL, What about cheaper gasoline price?

Sounds definitely interesting. Hope to see sometimes next year.
