While it might seem great on paper to go to an inline 6, I think we can all agree an Evo isn't an Evo without a turbo 4 in it. We don't want Mitsu to do what they did to the Eclipse.

 

no ,dont need it.
what do you think why the jdm subi is still 2.0 l?

 

That's oversimplifying quite a bit. Don't forget that designing a new block and new tooling costs money as well. The design parameters have to meet Mitsu's requirement for their 10 year powertrain warranty, US emissions requirements, and perform better than the 2.0L. This involves lots of redesign and finite element analysis to make sure the block can endure the stresses of daily driving. Then the engine has to be federalized all over again. Mitsu doesn't have the money or the volume to do this.

How does subaru do this? Because the EJ25T engine is used in every US product line (except for the Tribeca) and therefore they can amortize the costs of tooling and development across far more cars. The STI engine is basically the same as the WRX engine with a few component upgrades. These upgrades may be hard for a shadetree mechanic to install but they are trivially easy to do on the production line.

I think the previous point about Group N being far more relevant to street car technology and development is a good one. Don't knock the 2.0 in the X until you try it (and the mags actually get a healthy one to test).

^ that is why the subaru the 2.5 liter subi engine is limited. Basicly they put the forester engine in it..
The real sti is 2.0 l everywhere else. And that is amazing and equaly good engine, with the 4g63...

 

Subaru is using what amounts to nearly identical 2.5L engines in all its turbo cars these days, which is great for reducing costs. There are some tweaks to the pistons and heads depending on the model and year.

And the ONLY market that gets the 2.0L STI these days is Japan. Everywhere else in the world gets the 2.5L now. I think most people would agree that while the 2.0L STI has a nicer overall package in stock trim, when it comes to modifying, the 2.5L is a better base to start with.

 

well ,then how do you explain in europe /hungary/ you buy the 2l version.And when its comes to modifying the 2l is only with bolts on get more whp then the 2.5l .... Just like the 4g63. It is very identical the whp gain on the 2l vs 4g63.
Some guys imported the 2.5l from usa/wonder why ,if they can buy it in europa/ and turn out to be a verybad decision from them. As i heard . The new sti is might be only 2.5 every where else but japan. So i can't comment on that. Not one of my friend have the 08 one.

 

The European STI is 2.5L. Everything but Japan. As of 2006 if I remember correctly. You may be going on pre-2006 information. There are also a couple places that only get STIs at all by importing JDM models -- but those are still JDM STIs, and I think they're all much closer to Japan than Europe.

 

that is could be since the newest STI they running is 2005. And they are exactly as a JDM only difference is the left hand drive.

 

wrong. the JDM sti is a 2.0

 

if that's the case, then why is it that EVO's make more power with a 2.0 mod for mod?

 

the evo will get the 2.4 in 09 or 2010, because the rallyart will have a turbo 2 and the EVO will have to be one better. They want to iron out any issues with the new drive train and then the 2.4 is coming, its the obvious easy upgrade. The X stops quicker and corners harder than the IX, no doubt it needs the 2.4.

 

the 2liter real sti engine is blowing away the 2.5 one . I just talk to my friend. The reason you can get easier the 2.5l engine type ,because it is CHEAPER!! They importing from the USA. Meanwhile the jdm is cost almost 35 % to get it as a dealer!!!! So when actually get on the market cost over 50% more! So ,so many people dont hook it up anyway so they stay with the cheapest. And that cheapest cost in hungary over $43k out the door!!! Remember there the people make a half money avarage then here in the USA. So it is a big difference that %50 extra to get a EU version/aka JDM/
