A few more questions to ponder

[rsholland]

this weekend, while waiting for Monday's SOA Detroit announcements...

1)
If the STi engine indeed is a 2.5L engine, do you think it will another version of the PHASE II platform (the final version?), or will it be the first of the long-rumored, upcoming PHASE III engines?

2)
And, if it is a 2.5 turbo, do you think the base WRX will remain a 2.0L engine? Or, will it too get a 2.5L engine? My guess is, once the 2.5 turbo debuts, eventually all North Americian H-4 engines will be 2.5, at some point. It may take a few years, but I think it will happen.

3)
Which auto rag will be the first to do a comparison test of the new US-spec EVO and STi, and which issue? And, of course, who will be the winner?

I will bet that that Primedia will do the first comparision and it will appear in all of ther mags at the same time.

[LinuxGuy]

im 99% sure subaru will ---~~~~******NOT******~~~~--- use the EJ25 in the WRX STi

[Brahmzy]

This topic's been beat to death, but I agree, in my infinite wisdom...the STi WILL be a 2.0L. Any PayPal bets?

[ANZAC_1915]

1) While it might be called a Phase III (or not) I think a high output 2.5 turbo would need a very strong crank, block, rods and pistons. If it is a 2.5 big-T, I doubt it is just a 2.5 Phase II motor with a big turbo stuck on it.

2) It would make sense to keep the WRX a 2.0 --- it is then easier to differentiate the 2 cars.

I have no idea why would somebody think is going to be a 2.5L, where do they get this kind of info? Why not 2.2, 2.3, 2.4, or 2.6??? As lease I can tell you is going to be 2.0L because thats what the rest of the world is getting.

[koolaideprived]

Where do they get this info? Well, it's not really info, more speculation, and a few hints from people "in the know". Why 2.5 and not 2.2, 2.3, 2.4, or 2.6? Because the only engine that subaru has consistently developed for the NA market is the 2.5, and it would make sense that they would use their knowledge of that motor, with the added boost of a turbo.

[HOKWRX]

Some prove would be nice

But a High HP 2.5 litre motor is an untested engine ( I know there was that trubo 2.5 truck motor awhile back) Whereas the 2.0 is a 10 year in the making engine.

[Charlie-III]

I have said it before on this forum.

Old thread

SOA WILL launch a 2.5L TURBO Impreza SOON.
Lets just say "I know someone in SOA in NJ."
Take it or leave it.

I was simply saying why I believe that they would use the 2.5 and not some newly developed 2.4 or something. I personally think they'll bring the STi over with the 2.0

[firedog25]

One thought here... this is about the FIA rules when it comes to displacement for WRC cars... isn't the legal limit on FIA homologation blah de blah blah blah 2.0 liters with a turbo? IF so... then why would Subaru come out with a 2.5i turbo WRX? Wouldn't that just defeat the purpose? I can see it for the Legacy B4 since it is a much heavier car, but for the Impreza line? Unless FIA rules have changed, I don't see them doing the 2.5 for the WRX and it's kin.

Just my $.02

[ecfitzgerald]

AHHH! WRC has NOTHING to do with it. Theyu only have to make 50 of them to homoligate for WRC class. And the STI we get will not play into any homoligation rules for the FIA. Maybe SCCA for pro rally and the speed channel series. I don't know or have a stong opinion about what engine they will use. They both have their pluses and minuses.

[DuoMaxwell]

LOL its funny if the STI does get a 2.5l you will still be getting spanked by the 2.2 and the 2.0 that people have installed, not to mention there is no market for the STI as a 2.5L Turbo you will be waiting for parts like crazy. Also I am sure alot of people will want it but with a price tag of 40k or more I highly doubt to many people are gonna shell that kinda cash out. And I repeat myself your friend in NJ is wrong they have no plan of making a 2.5 Turbo for the REX for the next 3 years. Try Legacy!!!

[Porter]

They built a non-turbo EJ25 STi in Japan for years!

Why wouldn't they expand on that project?


I believe it was called the Impreza SRX or something like that... the STi version SRX is the one I'm referring to. It was a DOHC EJ25 with vvt and STi heads, and put out power right around 195-205hp NA. There were also 2.0L NA versions from FHI called the SRX as well... the STi was the larger displacement version.

There's a whole club for these guys in Japan, they whip up on WRXs over there by doing NA buildups... but my point is that there's already been an STi 2.5L Impreza before. Not a turbo one, but still a 2.5L, and it did get a significant amount of engine development.


I say the STi has a very good chance of being 2.5L... far easier to meet emissions that way, and there is certainly enough demand in the US market to build a special model. The RS was a special model!!!!

[Kevin]

What kind of drugs are you 2.5L Turbo rumour guys on?
Have you not already seen all the specs and pictures of the new STi from Japan and the UK? Do you really think Subaru will develop an entirely new engine for the North American market?
Smoke another one......
*And I'll gladly eat my words if they do bring out a turbo 2.5L

[jaybird]

FWIW I've heard the STi will be a EJ25 as well. I just brushed it off. Why not though? It's really not that much of a stretch maybe they couldn't get the power they wanted out of the EJ20 on normal gas and pass emissions. Why would parts be so scarce? They already make them. EJ20T OEM parts aren't exactly plentiful.

I'd like to see a three way in the mags. STi vs EVO vs VW R32.

[Bolster]

I'm thinking Subaru will have so much money in the STi's 6-speed tranny, Brembo brakes, upgraded suspension, I/C sprayer, new exterior, and so forth, that in order to remain competitive, it will resurrect the good ol' 1.8 non-turbo from the early-to-mid 1990's. I have very reliable information from my astrologer.....

[firedog25]

I wish I lived in Detroit or somewhere near. We got peeks at the Evolution (whatever number it is here now!), the VW R32 (very sweet), but no STi, they're supposed to do something on the 11th or something though. Subaru's people didn't really even have any info about the STi or it's engine when I was there.

P.S. I agree with Kevin... Puff puff givvve 2.5 rumor mongers!

[DuoMaxwell]

The hopes and dreams of a few for a 2.5. Oh well like I said try B4 Legacy that is where Suby is really heading. Its kinda like a luxury sports car and almost puts out the same numbers as an STI. I promise you if your friends know as much as they claim to know they will find out the truth about the new Legacy under developement. Besides you can go to any Suby dealer look at a full size Legacy wagon and see its TT and has LSD and pushes out 280 ps over here it has every thing the STI has but in a family wagon version. Not that I know anything or not but the B4 is whats in store for a new Power Plant upgrade.

[bluesubie]

Another question to ponder.

I wonder if the Sportshift will make it's WRX debut in the STi?

-Dennis

[tnbd]

So if there is a 2.5t it would be expected to put out a bit more torque then a 2.0t. Would the 6spd be capable of keeping up with the engine?

[SUBE555]

#1-Perhaps they use some slightly modified gear materials if it can't, put it this way STi engineers have it figured out.

#2-I seriously doubt any automatic transmission will be in the STi, so leave it alone. If you want an STi learn how to drive stick or get a plain ol WRX with the Automatic and Sportshift and try modding that up to the level of the STi. Learning to drive stick is much easier and cheaper, plus it's a hell of a lot of fun.

I don't want an auto STi, just pondering. I do drive stick. I read in a magazine recently that Mitsubishi may bring over the EVO with a sportshift-type auto. It's currently available in the JDM.
I wouldn't be completely shocked if we get one.

the Evo is available in a model called the GT-A in the UK. it's got a bit less power/torque (due to the auto not being able to take it I believe).

the UK mags I've read sorta dismiss the car as a "what's the point" exercise, since when you take away the power & the manic nature of the Evo it's just a sorta small car with AWD, good power & not much else. as it was also sorta expensive (pricier than the standard GSR-based Evo) something like an Audi, BWM Xi, etc seemed a better alternive to them.

I think there was also talk of doing an Evo GT-A wagon, but I dunno what became of that.
