What is the min. fuel grade for this car? I have just brought it and and the manuals are in Japanese (hopefully it is 95ron.)unlike the STi.

Whilst I am at it, -
- what are the recommended typre pressures front and back
- when should I change the timing belt

again can't read manual! Is there any other sourse for Legacy GTB info around?

Thanks in advance
Alex

 

AFAIK the GTB has essentially the same engine as a Jap-spec Impreza STi, so you'll need to use SUL plus an octane booster.

Shell Optimax is 98RON, so with an octane booster will be close to 100RON, like Japan.

 

Thanks for your comment NBW, I had heard that the legacy GTB was not do critcal on fuel from an old thread, which is a bit of a pain as the search is no longer working!! I am using std 95 ron at the moment with gentle driving, will this mess up thew engine?
Are there any other Legacy GTB drivers out there?
Cheers
Alex

 

I've had a GTB for 45,000 miles and it will run on 95RON, but it won't like it, it is much better on SUL and even better on Optimax, it also does more MPG on optimax, more than outweighing the extra cost (Provided you don't take too much extra advantage of the smoother engine and extra power)

Really suggest a search on the yahoo group: legacyb4

There is quite a lot you can do, but while it is less *sensitive* to fuel, it can be more sensitive - if you try to drive it hard on SUL, it can cause damage - big time

It is also more sensitive to poor or halfway mods...

Which gen of GT-B - or did I miss that?

Cheers.

 

Thanks for your comments, the car is a new shape Legacy MY99 manual that was imported from new. I've done about 600miles on 95 ron at the moment before noticing the sticker on the filler cap - super fuel only...!!! For your 45k miles, what percentage was done on 95ron?
I will try the optimax. On another point the sti has sliglty higher torque at a lower rpm but the same bhp, what is the difference in the turbos or is it the fact that both turbos are working at the same time?
Cheers

Any other comments/inputs

You've a heavy car being hauled around by an engine that likes to see less kilos - the idea behind the TT was to bring some torque down the rev range, but they were not trying to beat the WRX in performance terms as the target market was/is different. The aim being to create a fast saloon/estate that many people could afford and enjoy - it has been a huge hit and other makers have been trying to cash in for years (and are still playing catch-up)

I once had a service station put NUL (95RON) in once (yes, most of them are still full service ), and the was a bag of the proverbial and was reacting like something was badly stuffed - my dealer/doctor diagnosed it quick smart and prescribed a large dose of booster and many top ups with Hi-octane to get things back to normal. That had the scenery in fast-forward again

btw, just changing the back box can really help - some of the guys in the UK on the B4 group are arraging a group buy of top of the line Japanese back boxes that should be pretty nice (natch you'll need to make sure you get one for the wagon as the tail length is different).

Try this place - heaps of info and like minded people:

Have a good new year!!

 

Thanks for your comments, I agree with you. The GTB is not trying to be a WRX, but the handling is still OK though.....
My comment was that the maximum torque (and we all want as much as possible) is approx. 10% down on the STI but more importantly at much higher rpm. I agree the fist turbo brings much more torque down at useable revs, if you were switched the main turbo to the sti turbo, the spool up time would make the change over even more noticable? Have I answered my own question!!
Will the better tail pipe bring the maximum torque further at lower revs? I guess lower back pressure will do this.
I have joined the Yahoo/Legacy bbs - how many GTB/RSK owners are in the UK?
Cheers

Alex - take a look at this:

http://www.lumine.net/subaru/legacyb...owercurves.jpg

The R Evo brings the curve waaay down.

The car is not an STI, and changing stuff will likely break something expensive without due caution. You really need to be careful...if you want to find other owners - get on the mailing list

Cheers

 

Hey Man, why R U skimping on a measly 5p a litre using 95RON.
Put in the SUL and be done with it. U spent all that hard earned doh buying the car and then risk an engine rebuild for the sake of 5p per litre. Man I'm off back to sleep for a hard earned 40 winks....

 

Ahhh that was needed... now I can read the rest of the thread.
Just notice you've taken on the advice and spotted the filler cap.
You should have no more sleepless nights now. Not like me I have sleepless nights thinking about sleepless nights... back to the couch again for a daytime nap.

P.S did u know Optimax has a minimum of 98RON and is more likely to be 99RON. Why can't we have 100RON like our Jap friends? Must be something to do with profiteering I guess!

 

off topic, but I used to complain about the cost of fuel here...then when I was not looking the UK overtook - or Japan get a lot cheaper?

I once took a Skyline Turbo to Australia - sounded like it was about to spit rods, pistons, valves and dummy all at once - had to have an ECU made to handle it! Things are a little better now.

 

Hi Dougal,
I am now using Optimax, I did assumed that it was going to be 10p/ltr extra like the tiger fuel - this is bit difficult to hanle when you do lots of milage commuting. The Optimax made the engine a lot smoother, much easlier to allow the right foot to get a bit heavier - so much for better fuel economy - alot more fun though.
Asbloke - what do you drive now?
Alex

 

Kinda slightly off-topic, but the Legacy I'm looking at had the knock sensor disconnected by Well Lane. Is this part of a conversion to allow the car to run on UK fuel, or is it a bodge to stop the ECU complaining?

 

Notorious - that sounds like a dead knock sensor waiting to be replaced From memory disconnecting it will show a CEL...at the least I would imagine the engine would go into protect mode.

Is "Asbloke" me? In that case, sign me up as a B4-RSK owner (nicely *tweaked* ). Formerly a BG5 GT-B owner.

Closet "GT-B e-tune 2" lover

 

Sorry AJbasebloke, in a hurry at work.....

What a "GT-B e-tune 2" - sounds good!

Since your suggestion I have fitted upgraded brakes on the front "Green Stuff", with their own pads. What other mods have you done?
I do not want to do anything the engine, just suspension/handling. Is there a Prodive equivalent set-up for the alighment?
Cheers
Alex

Hi NotoriousREV, I would dearly love to get hold of at least the instruction book in english, if not the manuals. I have a local mechanic who seems to know his way around the car - ex Subaru - Hampshire area.
Alex

 

OK, back to answer about the e-tune 2...

It is the luverly current version of the GT-B (D rev). A bit stiffer bodyshell, revised steering, stiffer rear end etc., etc. Subaru did the usual on the big-midlife upgrade and worked magic on many of the little niggles of the early cars (new ECU/sensor set too - much more reliable AFS and O2(lambda) sensors).

In fact you can add the rear "side performance arms" to any of the older BE/BHs - check out the following page:
http://www.lumine.net/subaru/legacyb.../perf_arm.html This will help cure the wiggle at the rear you can get when the inputs get too much for the subframe to hold steady (the rear wheels can actually move quite a bit fore-and aft).

I want one a D rev car - actually I really want a D rev Tommy Kaira 2.2 - now THAT is an awesome vehicle - 315ps and bucket loads of torque <where's the drool smiley?>

Cheers

 

 

Dead knock sensor? Hmmm, sounds like a ballache.

Anyone know of a GTB specialist in the UK?

Are english workshop manuals available?

-Edited to say sorry for answering waaaaay off topic.-

I've done no *engine mods* per say - but got tweaks all over the place now - it is a desease that wilts the wallet

Suspension bits are my fav I have limited myself to end links (make a nice improvement to the poise of the car, try the Whitelines as they seem to be pretty good and cheap), rear ARB (nice, but not for everyone ) and ALK (very, very good for turn in, not so good for NVH).

I want to do springs but haven't got round to it yet

Basically it is handling very much like a RWD at the moment and needs to be a little less tail happy for my tastes (and safety on snow and ice ).

Otherwise I have stuck to getting very good rubber (mostly coz I hated the RE010s since they were on my BG) on light weight alloys.

Otherwise I have played with a lot of other stuff - but I have to say I have concentrated on keeping the car within warrantee limits. This could go on for ages Why not join the B4 mailing list to hear from the many mems around the world who enjoy their TTs to the fullest.

Natch, I don't mind answering here tho.

Cheers
