I read on a few random official subaru pages hinting that the VTD Auto in the 02 wrx was nothing new.

Nasioc "experts" wouldn't here of it. The 02 WRX was revolutionary and new.

They didnt think it was odd that the WRX and SVX where the only ones to ever get the odd 3.54 differential

I even posted an image of the WRX center differential and the SVX and they looked identicle. Now I have proof.

1991
Alcyone SVX equipped with advanced sport AWD system "VTD-AWD" introduced.

I feel so much better now. Just shows that even those considered experts on the forums aren't always right. Also just because 10 people say your wrong it doesnt mean that its true!

Now on a related topic, did the SVX have the manual button on the shifter?

I believe it did come with a manual button, lemme find a pic to confirm. Yeah it's got the manual button

COOL

Now to find an SVX TCU.....

i knew that

Ciper, if there's one thing I've learned about a lot of folks up on Nasioc, is they're not all as open-minded as they claim to be.

I caught all kinds of hell because ONE person claimed I didn't invite ALL Subbies to the STi/Evo meet last week. . .. when I brought up my original thread clearly stating that everyone WAS, in fact, invited. . . . (was an unaltered and unedited post, mind you) . . . . ten minutes later one of the mods deleted the entire thread from the forum.

Guess some of the "OG" folks over there have WAYYYYY too much pride. . . .




. . . . in themselves.

hehehehehe. I can only imagine........

they love drama. that's my only theory.

Eh, either that or many of them have insecurities which make it hard for them to welcome new members to the board.

Either way. . . they know everything, and we know nothing.

My take on it is that VTD has been around since the early 90s, but it's not clear which markets got the SVX with VTD.

I don't think the United States did, since Subaru released a TSB talking about the multiplate transfer clutch binding which applied to Legacies and SVXes both:

http://www.graphics.cornell.edu/~v/pics ... -62-97.pdf

The 3rd-party SVX wiring diagrams I've seen also include an FWD fuse, and I remember people mentioning the fuse in posts elsewhere.

As for NASIOC, that's one of the reasons I don't go on there so much...

See, vrg3 was able to disagree and do it right. That may be the case.

I love the shrugging smilie. Perfect for this stuff.

So... who has a friend with an SVX? All we want to know is whether or not there's a fuse underhood near the passenger strut tower labeled "FWD."

my friend used to have one, but it cost him too much to repair so he sold it to some kid who crashed it the next week. :\

anyway here's my contribution to the thread
http://www.subaru-svx.net/forum/search. ... descending
there's more than enough posts about a FWD fuse to make me believe the AWD versions had this.

i have a friend with 3. ill ask.

Yeah I would also believe that the US markets didn't get the VTD system.

So its most likely that overseas the SVX got the VTD while we got a normal transmission?

I found this page:

http://www001.upp.so-net.ne.jp/missingm ... x/svx.html

Let's see if I can paste in a machine translation of the relevant section...

　「SVX」の4WDシステムは、前後輪へのトルク配分を可変する「VTD-4WD」である。
4WD system of "SVX" is "VTD-4WD" which carries out variable [ of the torque distribution to an order ring ].
　前モデル「Alcyone」で展開していた2WDの設定を廃し、4WD専門のスポーツスペシャルティを目指して開発された。
A setup of 2WD(s) which were being developed by the front model "Alcyone" was abandoned, and it was developed aiming at sport SUPESHARUTI of 4WD speciality.
　「VTD」とは「Variable Torque Distribution」の略称である。
"VTD" is the abbreviated name of "Variable Torque Distribution."
　「SVX」に採用された「VTD-4WD」とは、4WDの高いスタビリティはそのままに、不等&可変トルク配分により後輪駆動車に匹敵する回頭性の良いスポーティなハンドリングを実現した、当時としては革新の4WDシステムであった。
It was 4WD system of the innovation as that time which realized the sporty handling with 回頭性 sufficient [ "VTD-4WD" adopted as "SVX" ] in which high SUTABIRITI of 4WD matches a rear-wheel-drive vehicle by non-等 & variable torque distribution as it is.
　ちなみに「SVX」では通常時、前輪側36.4／後輪側63.6の不等配分比率に設定されており、この比率を電子制御油圧多板クラッチ（MP-T）によるLSDの働きで走行状態に応じた配分を行い、前後輪のトルク配分を36:64から直結（50:50）まで可変制御する。
Incidentally, by "SVX", at the time of usual, it is set as the non-等配分 ratio of front wheel side 36.4-/rear wheel side 63.6, distribution according to the run state is performed by work of LSD according this ratio to an electronic control oil pressure multi-board clutch (MP-T), and variable control of the torque distribution of an order ring is carried out from 36:64 to direct connection (50:50).

Not like this is an authoritative source or anything, but to me it sounds like he's saying the SVX's VTD system was still based on a multiplate transfer clutch, but set up "backwards" as compared to our Legacies; drive always goes to the rear and the MPT clutch can send some to the front. The default split is 36/64, but the MPT clutch can fully lock up if necessary, making the split 50/50.

Interestingly, it also lists the final drive ratio as 3.700 rather than the 3.545 US models got.

Many other Japanese pages I've found also mention the "36/64" figure and the 3.700 final drive, and a few others also speak of an oil-pressure-controlled clutch involved in the VTD which can go to 50/50.

A 36/64 split isn't possible with the 4WD system in 4EAT BC/BFs, so unless all these Japanese guys are making up the same lies, there's gotta be a different system. If I understand it right (a big "if"), there could still be a "2WD" fuse, but it would lock into RWD rather than FWD. I doubt Subaru would label an "RWD" fuse "FWD."

So... yes, I think I agree. I think the US market got the "normal" setup while at least some overseas markets got a VTD.

I don't know anything about the current VTD system, so I don't know if the SVX's VTD system is the same or different.

The US market SVX does not have VTD,and they do have the FWD fuse like the Legacy.

Decided to ask SOA about it:

Dear Mr. Jones:

Thank you for visiting the Subaru Web site and for your inquiry.

I think I can put some of the confusion to rest for you. The SVX models do not
come with VTD, as VTD was introduced here in the United States in 2001, along
with our VDC Wagon. Your SVX model year was not mentioned, but I can tell you
that the 1992-1994 models were equipped with Subaru's standard AWD system. The
1995-1997 models had the limited slip differential.

I hope this information is helpful to you and answers your question, but should
you have further questions, please let me know and I'll do my best to assist you
further.

Best Wishes,

So I'm also going to have to lean on only non-usdm svx's had the vtd-awd

Funny,
Last week I had a freind have an invite deleted and he was docked "points" because it was deemed to be a commercial post because it was for the Cobb meet in May. Us members of Cobb's forum put together this national meet and Cobb just agreed to let us have it at their facility. Nothing commercial about it at all. I believe this occurred in the NW regional forum. And turns out the Mod had one bad experience with Cobb a few years ago and now anything Cobb bothers them (names have not been mentioned to protect the guilty) There are quite a few people over there who need to get over themselves. I am member #832, but literally did not log on for 2 years because I was so fed up with their BS...Back on topic...

Good to know about the SVX tranny. My option for my build get wider everyday.

I know what you mean. I'm member 2697 (because I was just trolling around the boards for 6 months or so before I signed up) and I have seen the board completely degrade over the years. I think it's just the sheer number of people that are on that board nowadays . . .

Impreza

I think that's why I like this board so much. More personal, less ego . . . and considering it's based upon a car that is no longer built anymore, I think we can count on it not growing to nasioc proportions.
