Suddenly the task gets more complicated!
More time on eb@y...

Thanks Paul for reply.

Graham

 

Graham, perhaps I should have explained myself...I was suggesting a phase 2 UK box, because it is plentyfull and relatively cheap to buy. A good one would leave you with all the necessary donor components for a ppg build and a long 5th gear. To that you you can pick and choose your front and centre diffs at will, afterall you are likely to want to change things, like front diffs etc. But, as Paul says, the ideal donor box, ie needing nothing more than the gear kit, would be from an Sti 5/6 Type RA Limited, but they're like hens teeth! The alternative is to buy an aftermarket ATB (Quaife/Kazz) or plated (Kazz) front diff and at some later date source an uprated centre diff or DCCD

 

The biggest issue with this, is that Graham would need to use something other than the UK transfer gears or transfer box assembly, and ideally needs to retain the 4.44 diff of his existing box for the hillclimbing. All of that kind of misses the point of getting a complete box to build the kit into so you can do a straight swap. If you're not worried about the front diff type, then a v5-6 regular sti box would be the ideal starting point as it has the right CWP on the front and the right transfer box ratios meaning it can be built up with the PPG kit and then swapped over in a single half day.

Getting closer!

I am not too sure if fancy diffs will make too much difference on a hillclimb; I think using slicks will have a more profound effect on times and provide far more traction/grip coming out of bends.

Driving the thing better also has a marked effect...

The 2 reasons to do this in another box is to have a quick change over (though I think you can do the change very quickly Paul!), and also to allow me to sell the trick trans when I tire of the Sti as I will have the stock trans available.
I hate changing rear diffs anyway so a Jap 4.444 trans as a donar is the way forward.
As ever, thanks for all the time/info from you both.

Graham.

 

Graham, trick diffs make a huge difference...maybe when I get my car running I'll get to show you what I mean...Surtrack Subaru front, Quaife ATB rear...oh and and now an engine that should make more use of the 6 speed gearing

 

Graham: How are is the AST setup in terms of 'squat' when launching?

How adjustable are the dampers?

 

There is no squat. Might be why the traction at the standing start is weak?
The 3 way adjustment is very effective, but it does take a bit to work-out what is going on in the car over a given surface, but they are very effective.
I think you can run them on a softer bias compared to the 'simpler' AST's of last year.

I think i have some further tweeking to do, but more of a refinement rather than adjustment.

Graham

 

Thread hijack - apols!
What Trick Diff options are there / what sort of cost - not sure what LSD type diffs my JDM 1994 wagon has ... certainly no front LSD as no traction if one wheels spins in mud/snow! What should I have as std? ( viscous centre ?? only ?)

Cheers

Hijack over.

 

I think you will have the center only.
Again, I think the Sti had an open front and a viscous rear in addition, and the Sti RA had the dccd and the plated rear...

I think!

Graham.

 

I downloaded this a while back, not certain it's 100% accurate but if nothing else it gives a guide.

 

Cheers Carl, looks about right! Saved it but a sod to print!!

 

Graham, im starting to realise now as i get a chance to push my car a bit more that the Helical front LSD i put in my new box has done its bit to add a fair ammount of front end grip to my car. It certainly turns in far better than it did before with an open front diff.

 

Danny: thanks....more money to save up!
Graham

 

I had a blast the other day on the back roads near where I live, I'm getting used to the hard setup, there is no understeer from the suspension setup , only power understeer. A new front lsd diff will be added to the gearbox package. The left rear still clonks, escpecially when it is unloaded, something not quite right with it. The cornering speeds give an enormous gravity effect

Andy

 

Minimal squat = good for launches......too hard though and the car can 'bounce'

What do you mean by 3-way adjust? Only three damper settings?

 

Bob'5

See message 285. Ohh the joys of a search!!

"I am now using the far more complex 3 way adjustable units where you can tune the damping to the rate for suspension compression and rebound, plus you can vary the rate of compression rate for fast and slow displacement."

 

Took me ages to write that!

No, they are really very very nice, but jumping from a single turn adjuster to 3 to 'integrate' is quite a step, but each of them really do work well.
Remember this is a £2000 set-up, and should be effective.

So far all is well.

Bob:

I raced against a 2.2 liter Legacy 10 days back and his car really does go up and down before going forwards...most wierd to watch. (beat him).

Unless you have educated spys at all the bends it is very hard to sort the car out on your own!

The car feels great on road and track now on the same settings, so I will go to Prescott 'as is' and see what happens.
The competition will be very stiff indeed.

Anyone got a shattered V6 Sti gearbox please?
'Wanted' section not coming up with the goodies.

Ebay frightening too!

Is DCCD really worth it?
Anyone actually driven a dog box on the road in notmal weekend driving?
If so, honest opinion please. (just think about bank holiday traffic)

Take a look at this

Seen that John.
Don't have the $$$ so won't mess about, but it shows they do pop-up every now and then.
Chasing a P1 box on ebay right now....
Graham

 

should of bought it at the price it went for

 

My Financial Director was not impressed/convinced.
She wants to save-up for the real thing rather than get bits and bobs over time.
At £360 it was a gift, but lots of 'Daughter's 21' and finishing Uni costs arriving in May....you have this to come.

Graham

 

£2000? not the ASTs in the recent Powerstation GB?

Bob

 

Bob:
I think Kev means the Ebay 'P1 or whatever it is' gearbox.
There is also a ppg dog box @ £2200 (iirc) in For Sale but Mr Wallis is after that.

Graham

 

Graham - I think Bob is referring to the AST suspension units!

 

^ Yep

Here is another one,.

It's getting like Swap Shop here! Who's got the jumper!!

 

Enough of the gearbox.

today was practice day at Prescott, and we ended up with 3 runs up the twisty hill.
My Senior Observer, Bigbrakes, was on hand so time for a bit of experimentation.

On the dry run in the morning I ran a 48.74 (pb is 48.09) and for once a decent start @ 2.13 secs.
I had the AST's where I left them after Loton, all seemed well although I had dropped the pressures to 30/28 F/R.
Second run was after a light shower but still a 48.99 @ 2.15 and 28/25 F/R
I had softened the AST's by one click on all 3 settings, and the car felt a bit 'wallowy'.
Sen Advisor has now nailed where I am slower than the EVO....

Third run was during a shower, with the AST's 2 clicks harder at the front than the rear 'softer' setting, pressures the same. Ran a good 50.02 but don't know the start.
Car felt good mind, and the F/R settings are better to the feel of the car on a freshly wetted surface.

Of course, the EVO is here, and a touch faster, but not all THAT quicker. Have I scared him?

Here are some stills for you of some of my fellow competitor's cars:

Commonly known as the 'White Car Class' wonder why?

Hope to have some vids tomorrow if the camera mode will work.

Hope it stays dry

Looks like a good day had today, although I thought you were going to pop in on the way home, never mind.
Got my seats fitted
