Has anyone fitted a grounding kit to their scooby? They are advertised in this months Total Impreza for £42 delivered. The theory sounds good but do they make any difference in the real world?

Been there, done that, but made my own.
A few metres of thick flexible cable from an ICE dealer, some ring terminals, and an hour cutting it and soldering terminals on.

I'd not like to say what difference it made, but the earth from the ecu WAS awful.........

My next mod in that department will be a multi-block for ALL my extra earths, and one from it to the battery -ve, rather than the spaghetti I have at present, all going to the battery.

waste of time, just make sure the ones you got are clean

Forgive my ignorance but what do they do?

nothing really mate, most claim a better ground thus giving more power/ response

So by implication you are saying that these thicker wires won't improve earthing over the thin stuff fitted by subaru

as long as the conections are clean, then yeah

Anyone got any fitted pics, either home made or bought?

Electrics isn't a strong point for me, and it certainly wasn't with Subaru.

And I assume this is based upon facts or relevant experience of fitting kits and seeing no improvement on how the car runs. Whilst I would not believe claims of significant power gains, I can imagine that by improving the earth you could get stronger sparks, more accurate and reliable voltages as a result of more stable and consistent earthing across the vehicle. This in turn would see overall better running of the car; the less the voltage floats the more stable things like the idle will be. Am I wrong

made my own for £17 with wire to spare.toolstation is the best place for the crimps googled pic to see how/where to fit.cleared a part throttle flat spot that my forrester had and that was only with half the wires fitted.i will be fitting some on my wrx for £17 and an hours work why not

CERTAINLY worth it for the ecu.
The jury is out on the rest, but it can't do any harm.........

I am glad I asked the question!! I reckon I will either get a kit or, after reading the link from Slipstream (thanks) have a go at making my own.

I got a HKS one off one of the guy on here cheap. looks cool as **** but cant honestly say they do much IMO but the BLING factor is well up there!!

better earthing is always a good thing replacing tired old wires id get it but my battery is in the boot

Can anyone suggest which earthing wires should be done?

alcazar

IIRC, mine are:
ecu,
n/s inner wing,
o/s inner wing,
front slam panel,
starter,
and three others I can't remember at the mo, and I don't have the car to check visually.

Look at the link above from Slipstream, it details which earths should be don.:

Left strut turret
Left front inlet manifold
Alternator
Front right inlet manifold
Rear left inlet manifold
Right strut turret
Chassis

ECU

That's good thanks. Is there a list of parts to get so that it can all be done in one hit?

That's how I did mine, I must have seen that before

TBH, it's not difficult: using the above pdf, measure, ROUGHLY the amount of cable you'll need in total. Add a couple of metres for good measure and buy it over the counter at a decent ICE dealer. They will probably also sell you the terminals, (you need 16, if doing the above), most are for 6mm bolts, but 8mm will do as well. IIRC, I used both, choosing appropriately. Mine is soldered and crimped as above. Soldering was done carefully over a gas ring once crimped, I didn't then have a soldering iron big enough to cope.

A goof tip is to buy the MOST FLEXIBLE cable you can get
And when running it, don't be tempted to sc rimp on length, an extra couple of inches is always better than a tight connection which can pull loose

Heatshrink can be had on e-bay, at Maplins etc.

If in doubt, try www.vehiclewiringproducts.co.uk
who will mail-order everything you need including the earthing block thingy, although not the exact one shown. Not the cheapest source, mind.

Do WRX models have different earthing points to the UK Turbo 2000 models?

The reason i ask is because the only kits i can find are for the WRX.

I read about these and as thought the THEORY was good. So having done over 20 years of military spec electrics including 7 years of vehicle electrics I thought well if they are that good lets check my earths and if needed make my own kit. I checked earth points to the chassis, followed by chassis to battery negative terminal (not battery negative clamp) and finally earth points to battery negative terminal. All readings were negligeable for differences so I would say that on a seaside living car they could be of benefit as the salt air will speed up corrosion but otherwise a bit of a gimmick. I own a 02 bugeye that on original internals/wiring happily pushes out over 400 bhp. These are my findings and I am sure someone will say on my car it did improve things, all that says to me is that a bit of maintenance could have saved some cash.

hi ive not been on for a long time but will try to look in as often as i can i recently bought a grounding kit from a seller on ebay fitted it in 20 minutes and i have to say ive noticed a difference in particular throttle response and a smoother idle he asked for some photos and is using them for his posting i am useless at linking to other sites but if you search for subaru grounding kits you will find the listing the kits come in defferent colours heres the blue set fitted to my car
