New Rumor: Subaru Developing Turbo 4 2.0T for BRZ

Iono if this truly does happen if I should go this route or get a Non turbo BRZ now and get a Vortech SuperChanger later.

IBTL.

I think this rumor about the Cygnet/iQ getting the Aston Martin V12 comes pretty close to the nuclear option...

saw that as well. would be completely insane if they built that. unfortunately, the iQ isn't a very good handling car so driving it wouldn't be as much fun as one might think.

On The Turbo issue: Though it might be easy for Subaru to smack on a turbo, I would think that they wouldn't do it to keep the WRX and STi farther up the food chain than the BRZ. Until BRZ becomes a solid, higher volume car, I can't see them spending much capital on it.

On the "Honda is a better value" argument: As others have said, I think that argument simply missed the point. If some dealership offered a 4x4 truck with many more features for the same price as a BRZ/FR-S, I would still be more interested in the BRZ/FR-S because I don't want to commute in a 4x4 truck. I would not buy an Accord EX (with more stuff) because I don't like FWD- no matter how much "extra" you get with it.

At least now I'm seeing more FR-S / BRZ sales without the huge over-the-top mark ups.

Thanks to those sales people who talked about customers, very interesting. I agree that many people don't really "like cars," and see them more as appliances that you "have to live with."

I'm not liking the line that said straight direct injection only. That's a big restriction in fueling for forced induction setups. Be glad you have a hybrid fuel system in your current car.

There are plenty of GDI cars that are also turbocharged. Why would you want or need port injection (or port along with direct injection) on a forced induction application? If anything, I think GDI is better suited for forced induction in the first place.

Ask GDI Audi owners why DI isn't the greatest.

Our engines with both GDI and TPI are the best of both worlds.

I just got my BRZ the other day and before i even brought up the rumour my salesman was telling my dad to not buy an impreza and to wait a year or two because the new BRZ is going to have turbo. So i guess it happening...FUCK

It is but it isn't. Think about it like this, in stock form direct injection is king with forced induction applications; largely because you don't have to use additional fuel to prevent detonation because the mixture happens in the combustion chamber and not before the intake valve thus allowing for a cooler mixture and increased volumetric efficiency.
This becomes a problem though when you're looking to turn it up a notch. The injectors atomize almost to the same extent diesels do; because your mixture happens inside the combustion chamber you end up with a limited time frame to form a homogeneous mixture. The only way to combat things going south is to restrict airflow, hence the reason he said there's a restriction in fueling because naturally if airflow is being restricted then so is the amount of fuel for stoichiometric purposes.

I'm actually a GDI Audi owner. If you're talking about carbon deposit issues, the current generation of TFSI engines don't have any issues. The naturally aspirated engines with GDI, however, are still experiencing severe carbon issues.

Here's a pic of my Audi:

My car is currently running 21 lbs of boost (instead of the stock 14 lbs) and there are no issues at all with keeping the air/fuel ratio in check. The GDI system is more than capable of adjusting fuel delivery & timing at increased boost levels.

You have to keep in mind that GDI has different combustion modes. For light loads, an ultra-lean burn mode is used. This is a stratified charge. The timing of the fuel being injected is adjusted towards the end of the compression stroke.

For normal loads, the GDI runs in stoichiometric mode. The fuel is injected earlier (during the intake stroke) and the result is a very homogeneous fuel charge.

For high loads (such as full throttle & full boost on a turbocharged car), the GDI goes into full power mode. It dumps in more fuel and creates a richer mixture to prevent engine knock.
