Good for you in persisting with somewhere for the legacy folks to find this kind of info.
I have a GTB MY99 and am always stuggling to find key stuff.
I will wash the car over the weekend and bathe it in Samurai wax from the boys at Swisol. Take some mug shots and whiz em over to your web address.
In fact I need some front discs and pads for it right now. Where do you suggest i get them from?
Do you legacy boys ever meet up anywhere in the south?

GTB Limited

Sushi,

thanks for the coments.

The discs are frt 294mm dia, so should be the same as the Impreza.
Upgrade to groves or drills, or both, and decent pads.
It's well worth it.

I have a set of no.s for the bg model, which will be on the site soon.

As for where to get them, PE sell black diamond disc, good for the money.
Depends on how much you wanna spend.

As for a meet, hopefully something in the pipe line.
Where are you?

Mark

Sushi, as Mark said, same as the Impreza 294mm discs, so lots to choose from. IMHO, stay away from drilled as they can be troublesome. So normal or slotted would be my humble suggestion (sorry Mark, too many probs with drilled IMHO).

As for a set of decent pads, I wonder if formula Ferodo are available in the UK? They seem to be a decent road pad from what I hear, and the new EBCs have got some good reviews from respected Scoobynet gurus (be sure to choose the right compound for the way yo drive though).

Also, join us on the legacyB4 group on yahoo - youll find a few friendly types who'll gladly share info.

Cheers

sushi

Thanks for the info. I am down in West Sussex. Half way through cleaning the car and sky opened up so those pictures may be a while!

GTB Limited

For all those who might of missed it


sushi,
Does that mean the back half is still dirty

I'm possibly looking to go to Bolney, for the jap car meet.
I'll make a decision shortly, then see if I can drum up some TT support.

Mark

sushi

stopped raining and finished cleaning with the wifes help.
emailed the pics to the address given.
is that |Bolney in west sussex on the A23 you are reffering to. I live about 5 miles from it!

GTB Limited

I gather yours is black, who's is the Impreza in the background?

Yes, that Bolney. You must of noticed it got a bit busy last year
The meet is at the pub.

Cheers for the pics.

Its an MY03 sti, bought it last August. share that and the GTB with the wife. Dog is not allowed in the blue one only the black one (and only to go to the vet if its dying!).

Recently had the geometry set up by Powerstation on the sti and have to say it handles beautifully now. Planning to have a remap in April with pipes and fuel pump so will find out what irs really like after that.

The GTB is on its third engine (piston blows or cracks both times) last time I took it round Goodwood and although I had a great day out with it, the engine oil got a little bit low and hey presto!!. I think we now check the oil level every other day - paranoid or what. Still the good news ia a new engine at 70,000 should mean for a long life ahead. every cloud........

masterwah

i live near chichester!!!

got a b4 rsk, just had ebc disc's on with green stuff pads. lasted a week b4 i warped them. waste of time, buy some 4pots. we should meet up sometime!!

will

AJbaseBloke

sushi,

3 engines My heart aches to hear that...

I hope you have a boost gauge and knocklink - sounds like something is not wokring well at all Which era car is it? If it is the one with the gammy MAF, then get a new one fitted as a matter of course IMHO. And get a decent earthing kit fitted to clean up the signalling (that is a straw grab but can't hurt).

What other mods is your car running?

Cheers

sushi

As embarressed as I am to say it I think the problem has been running twice with oil level below minimums.
Unfortunatly the oil warning light does not show on the dash board.
First time I only had the car a month and did not realize it would drink that much oil (Turns out about 1.2 litres per 3,000 miles). They rebuilt it at Autosportif under warrenty.
second time I was at a track day and checked the oil level before it cooled and settled down and so bingo again (cracked the piston skirts this time). Back to Autosportif - at my cost this time (ouch)
The car has no real mods. I am the second owner after the Garage manager at Prodrive - it was his company car for its first year of life and i believe the only alteration is some kind of crude chip. He said they looked after it like a baby giving lots of TLC (yea right!).
Whats a MAF?
I have never thought the car is very quick - given its BHP is supposed to be 280. its not until you thrash it at high revs that it produces any real zip. its max bar reading when I plugged it in was 1.1 at 6,400rpm. Top end is excellent will show 160 on the clock and hold it for a decent time. exceleration goes like a mini cooper s for example.
Should i be doing something else to it?

GTB Limited

sushi,

The term 'crude chip', worries me, definatley worth investigating.
'99 onwards can be Ecutek'd, so no need for a chip.

Secondary boost should be atleast 1bar from about 4600k, depending on gear, but certainly 4&5th.

MAF=mass airflow sensor.
I think they're hot film, on yours = temprimental.
It's attached to the airbox lid (sq block), just before the pipe work.

It's worth doing a 'code read' just to be safe (info under CEL).
If the MAF is going, the idle starts to 'hunt'.

I presume you run it on a diet of Optimax/SUL & booster?

Mark

p.s. your pics are up

AJbaseBloke

OK m8, let's see about keeping this one in one piece. If your car (and I suspect it is) is a BH5 A, B, or C revision car, the MAF (as capably explained by Mark) is a bloody nightmare as they can be duff and never seem so (oft the dodgy idle shows up quite late, and all the while the car can be running lean ). If the car is running the original MAF, the 70 or 80 quid investment to get the better replacement (which is still not perfect, but a definite improvement over the decidedly dodgy early ones) is smart money IMHO.

Later D revs get a better Denso set up which is less sus, but even they have been known to go out.

#1 deadly issue is low oil though. Note the warnings on these cars are set notoriously low, so regular checks along with some extra monitoring in your case (oil pressure at least) may be a good investment. On run in, using good dino oil is always a good idea for the first few thousand miles to get the rings seated. Although I have never had a drop disappear (touch wood!), I seem to hear about it happening on low km cars a bit thesedays, so be cautious running her in IMHO. I also discount the factory suggested oil change regimen and strongly suggest changes every 5000 miles at the most, with 3000 not a bad idea (in Japan there are quite a few who change every 3000kms, I rarely run mine beyond 5000kms coz the oil is usually very tired by then in my car). Change over to semi-synth of full later on (many say it is a good idea to do 6k miles or more before changing over).

Loosing oil at the rate, and regularity you seem to have is defo a concern. Have you noticed contamination of the coolant at all? To have it burning away at such a rate seems to suggest some other gremilins at work, but it is a bit late here for my brain to get a handle on it. Down on power is not a good sign either (although it will never be as quick as a Rex or STi in good nick), but 1.1bar is quite good boost for a std car... Me thinks keeping the oil in the engine is gonna help But how are we gonna get it to play fair? Hrm...

As Mark said, this "crude chip" sounds eminently dodgy too... A remap for UK fuel cannot hurt IMHO, and TLC with good juice and booster is not bad advice either. Knocklinks are smart buys too, of course.

But as you point out, no oil is gonna stuff it everytime...gotta get that sorted.

Sorry to have gone on and on. And certainly hope this helps more than it hurts.

Cheers

OK fellas - you lost me. As ever - these sorts of detailed comments raise as many questions as they give answers,

First off i feed it on Optimax only. Stopped using booster after the last rebuild.Autosportiv reconed optimax was good enough - should i go back on the boost?

Oil used is magnatec -fully synthetic i think - put a litre in yesterday only 2000 miles after last service!

""If your car (and I suspect it is) is a BH5 A, B, or C revision"" how do i find out which one it is -from there we can decide what to do abut the MAF and where do i get that from?

Where would iether of you go for the remap? I see Imprezza remaps available from every one and his mother but they all seem to steer clear of the GTB.

Mark. Ended up buying Group N standard 294 discs andpads from Graham Goode racing. Will they do the job?

Finally where are you fountains of knowledge based?

sushi

mark

they look good, thanks for blotting out the plate

AJbaseBloke

sushi,

I am in Japan, so a bit far for a get together (although I'd be interested ).

The "revision" stuff relates roughly to MY - BUT IT IS DIFFERENT for JDM cars, beause Japan does not strictly follow the model year, and trying to "MYxx it" results in tons of confusion. The easy way to find out what you have is to look at your model code (on the VIN plate) - it'll have a bit that starts with BH5 (that is the code for the last shape Legacy wagon w/2ltr engine) and the next letter behind that is the "revision". "A" being the first, "B" the 2nd, and on to D which was the last. Then there are models within the range to add further "confusion"

Those discs and pads should be fine - our brakes are the same as the ones on the Impreza (barring the floating 2 pots). As long as GGR knew which pad you needed, there should be no probs.

And the ECUTEK stuff is still relatively new, so if you are not a member of our yahoo community, that would explain why you've not been aware of the introduction of the TT version.

Cheers

sushi,


'a litre after 2k' , she's either eating it, or it's falling out the bottom.
Hopefully the later, should have a nice stain on the drive.
Can you smell oil after a good blat?

How many miles since the last rebuild?
Choice of oil is a minefield (due to so many).
As aj has mentioned, after running in, semi-synth followed by fully-synth.

Magnatec is semi-syth, but I find it's not really up to the job for TT's, gets tired quickly (engine starts to sound rattly) and dis-colours quickly.
Definatley needs changing at 3k.

10w/40 oil is the range to go for, certainly on semi-synth.
10w/40-60 on fully-synths.

Personal choice, Shell 10w/40 semi, though not use fully-synth yet, Castrol RS10w/60 gets good reports, and Millers do 10w/40&60 fs.

I change mine every 3-4k intervals, using a Subaru filter.

Octane boosters. All TT's run a 100 ron fuel map, for Japanese fuel.
Current max UK pump fuel is 98ron (optimax), 2ron short.
So you have high risk of 'det' (chocolate pistons), adding the booster reduces the risk by raising the ron count, hopefully to Jap spec 100ron.

IMO best 2 are Nitrous Formula (NF), 'race' product, though it's hard to get hold of, or Millers 'Octane Plus', get almost anywhere.

Ecutek have a website http://www.ecutek.com/
Worth a nose and a phone call, and can map for 98ron fuel.
Power Engineering are right next door
A couple of people on here have had a remap, and liked the results.

Last rebuild was around 7,000 mile back. Definatly not leaking but consuming the oil.

I will change oil and filter more frequently and go back to octane booster.

Will also check out the remop option

Thanks for the advice.

No probs
