I've searched... and I remember a posting awhile ago about a patent or something regarding an H6 turbo. I am wondering if there was any more on this or am I imagining things.

Next year! Twin-turbo H6 Legacy STi! I heard it from an "insider."

The B11S concept car was beautiful and offered a 400HP Twin Turbo H6 (well, 394HP to be exact). If only they would start selling them (with B9's styling cue updates of course!). (sigh)

I think the turbo six will show up on the 7-pax.

Popular Mechanics had article saying that 2006 models will include 350 hp legacy sti,
but I don't think that'll will happen that soon...
but if the legacies and new outbacks sell well, it'll happen, it's a matter of time...
even here in hot Phoenix, I see a lot of new legacies and outbacks being driven
I think the sales are going well

Popular Mechanics is the worse source for info re the automotive industry. PM might be good for all the high tech innovations that will show up 10 years from now, but I've found that the info they publish on the current auto industry is either out of date or completely wrong. I've stopped going to their website years ago.

Personally I rather see a Dual AVCS Twin-Scroll Turbocharged 2.5L H4 in the Legacy STi. That would keep cost down as well.

what i wanna see is a H6 turbo (wrx) sti :D

I think the current H6 just doesn't cut it.. it has less power and torque... then a 2.5 turbo... I just don't get it... Subaru absolutely needs a H6 turbo...

HOK, it's a lot easier to get power out of a turbo car than an N/A car. That doesn't mean it doesn't cut it to everyone though.

The problems I heard in development of the H6 turbo engine last I heard was that it was eating STi 6-speed drivetrains for every meal of the day with the torque it produced and it needed to have a direct line to a supertanker for the amount of fuel it was guzzling. Those issues may have been long worked out, they may not have. Just don't know.

I don't think they'd EVER put it in the Impreza platform because the weight (as size) doesn't make sense.

I believe this is why they never put the H6 in the Forester when people were complaining about the lack of power.

I agree, with upgraded parts and right tuning, it could make 350hp and sti 6mt eould handle it...

i would say never .. but then again that was the standing agruement about a 2.5 turbo too

the prototype SVX was a twin turbo H6
i wouldn't hold my breath

Next year! Twin-turbo H6 Legacy STi! I heard it from an "insider."
:lol:

if they make one next year imma be mad cause i just bought an sti , ohhh flat 6 turbo would own

What are you trying to say? I know its easier to get power out of a turbo car thats why I want the H6 turbo. I agree that getting power "initially" out of a turbo motor is easier. But with the resources at subaru they should be able to develop a H6 turbo no matter if based on NA or turbo. Ultimately it still boils down to displacement. With the direction that the legacy is heading (luxury sedan with bang for the buck) and competing against BMW and AUdi, they will need to develop a H6 turbo of some kind. I don't know if they will develop an H8 or larger. I owuld doubt it though. What are the developments you speak of (SUBE555) from subaru of Japan? any pages or reference? Whats wrong with breaking 6 speeds anyways? I don't see an issue here. :) If they do come out with an H6 turbo it should be on a 5 speed auto anyways.

To add to the H6 turbo side, If I was to pay for a 60 K legacy, it better not have a 4 banger in it.

You all laugh... but this is the next step where subaru must go... CALL TO ARMS! we must force them if nothing else.

Its not like us RS-T guys havn't done it before.... :P

I think the current H6 just doesn't cut it.. it has less power and torque... then a 2.5 turbo... I just don't get it... Subaru absolutely needs a H6 turbo...

I'm sure more power can come out of the basic H6 without the need for the Turbo (although would be a nice feature).

The question to ask is, with the MPG that would most likely have (what 9 City/12 HWY?), would it be worth it in todays crappy oil market?

I move for a good H6 Hybrid Turbo (if such a beast is possible)! As long as the MPG doesn't fall much lower than the '05 OBXT...

woooo good one... I like that... I heard there was a mitsu eclipse concept with 400 hp 205 out of the 4 banger and then 190 in the electric...

bleh! What's wrong is that many people, myself included, will not buy a sports car that is AT only.

You worked for Subaru during the SVX creation, didn't you? :p

All negatives aside, can you imagine how bitchin' it would be to have a Twin Turbo H6 in a Legacy with a good sport exhaust? It would sing like all the angels in heaven! :disco: :banana: :disco:

theres nothing wrong with a Subaru Tiptronic 5 speed...

If upscale refinement and power is where Subaru want to go. I think a turbo H6 is coming soon also. A low pressure turbo H6 3.0 would be the quickest way to get 300+HP and meet fuel mileage requirements. I would think they will have that as an option on the new Tribecca if not now, in the next version.

Maybe a H6 turbo with some cylinder deactivation enginnering added in ?

Just imagine the exhaust note.


Mmmmm Porsche. :D

theres nothing wrong with a Subaru Tiptronic 5 speed ... that the option of a manual transmission and/or sequential manual transmission wouldn't cure

Fixed it for you. :)

Gime the 2.5 turbo any day; the H6 turbo would be nice and all but for me, handling would suffer due to the weight and if you thought you hate understeer now...

how many pounds do you think the H6 is more then the 2.5 STI engine?

I dunno, HOK, but figure the extra turbo, more oil, more coolant, lines, and not to mention a heavier block... perhaps 50 to 70 lbs? Put that weight over the front wheel and not towards the center and its even worse

Get rid of McPhearson (sp?) strut and handling wont be much as a problem. I would most definately sell my rex for an twin H6. The low end torque for daily driving would rock, also you could get some nasty numbers from modifing it too..

Subaru's biggest problem right now is that the Legacy is priced in the same range as an WRX, having two models competing against each other is just stupid. The Legacy needs more options such as HID's, NAV. The G35x and TL are in the same price range but come better equiped making it hard for someone like my dad who is currently looking at a new car to consider it.

how many pounds do you think the H6 is more then the 2.5 STI engine?

Considering a 4 cylinder Outback vs H6 Outback (2004 and earlier, haven't evaulated '05s yet) has the difference of around 200 pounds, it shouldn't be THAT radically different...

there's nothing wrong w/ a naturally aspirated H6 as long as it produced Porsche levels of power...

Fixed it for you. :)
Better said Coati. ;) I'd much rather actually have input in the vehicle I'm driving, Autos don't interest me a bit.

The bits I mentioned were the last thing I heard on the H6's in development over a year ago. So that's been some time.

As for power and fuel economy... nothing variable compression and direct injection couldn't fix. ;)

there's nothing wrong w/ a naturally aspirated H6 as long as it produced Porsche levels of power...
True...but then you'll be having to produce Porsche levels of money. ;) :D

yeah, right...a manual tranny in a turbo H6...man, I can hear SOA pre-voiding warranties now:rolleyes:

with an auto, you can put MUCH more power down and remain a daily driver(good-by dogbox!). and with a better stall converter(higher RPM) you can use a HUGE turbo and not worry about lag...but you go ahead and keep dreaming about a manual-shift turbo H6...yeah, dreaming

I would love a legacy with a turbo H6. I would think they could sell a ton of them!

Why would I want to have a "HUGE" turbo? Why would a dogbox even be mentioned? We're talking about a Legacy, not some drag strip queen.

If Subaru put a manual trans in a turbo H6, it would be because they were certain that the transmission could handle the torque and horsepower. If someone turned up the boost by 5 psi and munched it, or did clutch dumps all day, their warranty should be voided.

Bravo!

how many pounds do you think the H6 is more then the 2.5 STI engine?

The weight difference shouldn't be that much. If you look at the stats/weights at Subaru for the Legacy, the 2.5T engine adds about 100 lbs to the 2.5 N/A. The H6 adds about 135 lbs to the 2.5 N/A.

Hence, I'd say the H6 is about 30 to 40 lbs heavier than the 2.5T, but I recall reading somewhere that the H6 was better balanced (maybe Shirokuma/Paul posted something to this effect), and that may be a function of where the weight is and where the turbo plumbing is. Bear in mind the H6 is only an inch longer than the 2.5T.

now, if you add turbo plumbing to the H6, then you're talking maybe an extra 100 lbs over N/A, which I'm pulling outta my arse, based on the diff. betw. the 2.5 N/a and 2.5 T.

I have an H6 turbo :) and it is 3.3l! http://www.subaru-svx.net/forum/showthread.php?threadid=21278

I do recall reading that the 7-pass would eventually get an H6tt.

Lots of powerful cars are available with MTs (Corvette, Viper, various European sports cars). I don't really see why its such an issue for Subaru to make or buy a strong enough MT.

they could, they just choose not to...

oh ok, you mean like the tranny the GC6's? I've seen plenty of those break without any boost, or abusive driving...but hey, what do I know?

The quote I remember is something along the lines of this (not an exact quote):

"Subaru realizes this (referring to 3.0 H6 not being powerful enough) and a 3.6 H6 is being evaluated for later models."

I've heard no mention of a Turbo model although again, the B11S DID showcase this recently...

Personally, due to fuel economics, I really feel as if Subaru may switch gears to offer a Hybrid model before anything else comes to fruitation (aren't all manufacturers required to by like 2008?).

Because the GC transmission was the peak of Subaru engineering? :rolleyes: That transmission was probably carried over from the early/mid 90's, back when most imprezas were the 110 hp variety. It would be insane not to offer a manual transmission in a possible Legacy STi.

The thing I loved about BMW until very recently is that you could get a manual in practically every model. The new M5 doesn't have one, which sucks, IMO. The E39 M5 was awesome. 6MT w/ 400 hp. If subaru came close to hitting that mark for $40k, they would have one magnificent vehicle on their hands.

~~Quentin

the hybrid is the way to go I think... I'm just wondering how you mod those to get more power hehe.. change brushes? coils?

I don't know if I really beleive that the 6 speeds weren't holding up to the H6 turbo.. I;d like to see some data cause those 6 speeds are monster tough...

I'm with Kevin also, if they have an application and have a desired system to be used, they will find a solution. They can make it fairly bulletproof. I don't really need to question that.

couldnthinkaone, you sure are dead-set against seeing a manual in that car. When I think of driving performance, the last thing I think of is an auto. I love that direct feel of a manual, clutch, shifter, and all. If an STi model was auto-only I sure wouldn't be buying one. SMG, good chance, but sport-shift, definitely no.

Now some of those other makes listed are putting 400-500 ponies down through 2 wheels while others have that much through 4 putting greater strain on the drivetrain, but they seem to be able to keep them together like Porsche and some others. The statement might be made about the difference in price, but it's really the basics. They can build a transmission to handle the power, I'm not worried about that really, just the last thing I heard was what they were supposedly trying with a V7 I think drivetrain. Things are likely much different now.

yeah...I guess I'm kinda spoiled driving around in MB's and AMG's with crisp, efficient, 5 and 7 speed auto's...I've become lazy in not having to drive manuals to go fast...that supercharged V8 and bi-turbo V12 really have ruined me for everything else. I tell ya, there's nothing like 560+lb/ft of torque from 2,500-4,500rpm to make you forget about the crappy 5-speed in your weak, N/A subaru...:( guess I need to anty-up for a 6MT conversion...

oh well, maybe one day I can afford to buy a real car and not just enjoy someone else's! :lol: but, thrashing someone's $200k car sure is fun! ;)

No doubt. Flogging a Viper GTS at Road America totally changed my notion of what "fast" is. It's one reason I'm not that interested in power mods. When a car has 450 lb-ft of torque right under your right foot...well, what's the point, really, of getting a 250-hp car to 300? :lol:

MBs are nice, no question. That new SLK (CLK) has me drooling every time I see it. People who say that the Corvette is the same price, so why bother, are missing the point, IMHO.

Scoobies have come a long way since your RS. Test drive a Legacy GT. The gearbox in that car is brilliant. Smooth, slick and luxurious-feeling, and the car, while not an MB, is a significant upgrade in fit, finish and interior appointments for Subaru.

Kevin

no doubt the LGT is much nicer than my RS, but I can't afford it right now. today is the last day for my job here in beaumont, and I'm moving to MB of Austin, which the owner happens to own a Subaru dealership as well(it's right around the corner!:D),and with the new baby's seat not fitting in the mustang(my wife's car) too well, a new LGT or FXT might be in my not-too-distant-future(either of which will be an automatic:p)...we'll see.

-scott

edit: eventualy I'll have a single turbo H6/auto in my GC body :devil:

I am so hoping for an H6 twin turbo STI ... Unfortunately I'm hoping even more that I could hit the lottery to be able to afford it ... :lol:

Y'know, I've bought like five lottery tickets in the last two years and haven't won. That's false advertising. I'm gonna sue.

Just think how bad its mileage would be. With current prices I don't think that will happen for a long time.
