Will a more powerful later version come with upgraded drivetrain throughout?

[Mulder]

I was just wondering to myself, (this is all speculation; don't harass me about not knowing what's coming) say the upgraded power option that comes out in 2015/2016 makes about 250HP. Let's say it's a 2.5L, but whatever it may be.

Since the stock internals, clutch, injectors, axles, etc all can reportedly hold up to about 280 HP, will the car just remain as it is for the most part? Or given the possibility of making even more power easier with the larger displacement, would they also give us slightly larger injectors, a stronger clutch, etc? To compensate for the upgrades that people will do, which would now easily push the car into 350 HP by adding FI.

If A happens, will B happen also?

My hope is to get a 2.5L, add a supercharger to get to 285 WHP (about 350 HP), and not have to replace the clutch and other items. What has Toyota/subaru done in the past in regards to introducing more powerful options to the market?

Based on the strategic direction of Subaru and their engines http://www.subaru.co.za/News/View/21...ies-up-to-2015 I see no chance for a completely new engine in 2015 or even 2016.

Let me go in the future and find out for you. Be right back.

"Of note on the technology side is a new direct injection turbocharged engine slated for introduction by the end of this year. And that's just part of Subaru's powertrain plans. According to a source close to Subaru, the company is currently working on a three-stage plan:

• Stage 1 (completed) - Direct injection 2.0-liter four-cylinder boxer incorporating Toyota's DS-4 technology for the BRZ
• Stage 2 - Direct injection turbocharged variant of the FA20 2.0-liter
• Stage 3 - High-powered four-cylinder turbo boxer for the next generation WRX. While the final engine capacity has not been decided yet, the consensus inside Subaru is leaning towards downsizing and tweaking the BRZ's FA20 2.0-liter unit into a 1.6-liter turbo featuring new lean-burn technology."

Good grief, none of that addresses my question. Didn't I say not to harass me for the speculation? I understand we don't know what or when is going to happen, just throwing a hypothetical question out there. If A happens, will B happen also?

I highly doubt that they will increase the horsepower especially in the first generation frs. Not even in the mid cycle refresh. Most likely in the second generation with a redesign.

Subaru's goal was to build a light weight sports car that also delivered great fuel economy. Their overall goal was a fun to drive sports car, not a quarter mile car. Compare this car to a S2K or the Rx8. How efficient is their fuel economy? Not as great as this car.

Perhaps later in the year, there would be a TRD super charger accessory just like something they had for the Tundra.

Did anybody even read my question before answering?

[Drobinson1692]

I think that's all unknown. It might be a safe assumption because they won't want the drivetrain falling apart under warranty. At the same time tho, turbo FA20's have been holding together pretty well so who knows. My answer: maybe.

You shot yourself in the foot asking about a bigger engine in a thread. ha!

To fully address your question, a lot would need to be changed to compensate the extra hp and to create it. There's many ways to create more horse power, 2 main ones is forced induction or a larger displacement.

In order for a car to drive with the added torque, it'll need a transmission that can handle it, also its going to need a reinforced differential. It's going to need bigger brakes, sided tires, and also a stiffer chasis.

What toyota has done in the past is tweak the motor and the transmission. Nothing significant, however Toyota has just made their cars more fuel efficient.

Without knowing the "what"? How can we say how that "what" will impact everything else in the car.

So let's try this:

Here's the list of engines for Subaru [ame="http://en.wikipedia.org/wiki/List_of_Subaru_engines"]List of Subaru engines - Wikipedia, the free encyclopedia[/ame]

Google what they did with the evolution of the WRX through the years and then you have enough to "imagine" what the future may or may not bring with the FA20.

And I know that the bigger engine statement clouded a lot because of all the nonsense speculation going on about monogram, release series, etc.

If anything, Toyota would probably be the ones to pull the trigger on a power increase. Subaru already has a more powerful car in the same price range (WRX), that they just completely overhauled. With that said, I see no reason why Toyota would do this at all considering FRS sales already outnumber BRZ sales 2:1+ (based on the sales numbers posted in another thread).

I only see a power increase coming if another auto manufacturer releases something to directly complete with the twins (there really isn't anything right now). When this happens, I would expect to see a fast, sloppy upgrade (2.5L engine, no re-work to internals), and a hefty price tag attached.

[dave77]

Lol, yea I bet they would change the drivetrain and fuel system a bit. I think they would want to have some "comfort room" or "insurance" on the parts when making the engine more powerful. Ofc, this would raise the price tag a bit.

[dave77]

I heard somewhere that a turbo FA20 won't fit into the FR-S/BRZ. So I don't think they'd do that for our cars, just for the WRX.
