Default grounding kit

Can anyone give some info on grounding kits, like the Hot Earth one for example. Will it do much for a stock WRX? And how easy are they to install? Thanks

Ryan

Kits are very easy to install, wether or not you will notice a difference...hard to say.

According to the packaging, the SYMS kit gives 5hp more. Of course all the grounding kits I've seen are around $100 (here in Japan at least) is it worth that much? and will you notice a difference is a good question.

I went to sounddomain.com and bought all wire and connectors necessary - spent about $30 or less, I think. Four-point grounding with distribution block. Kits are overrated IMO.

Why can't I link a pic???

I work at an audio place. I decided to change out the negative terminal out with a silver plated one. I then took a foot of 4 guage wire and attached it from the terminal to a distribution block. I ran 8 gauge power wire out of there to different ground points in the car.

Didn't feel anything. OH well.

I don't think you can gain HP by it but I have heard it in the past before. I use NOLOGY ground cable especially their spark plug wires witch come with their own ground straps, & they have different colors too! call nology & ask them about that HP they might be able to answer that for you since they do especialize on it. www.nology.com

I like the idea of using the distribution block. Here's where i stand now. Couple things im stuck on.

* Ive heard that chaining the grounds is bad.
* The strut towers are poor grounds.

So I'm working off the idea that i get 4 wires from the dist. block.

I figure one to each side of the manifold.
Then one to the passenger side fenderwall.
Another to the spot behind the IC.

Thats 4 spots there, i was gona do a short one from the neg. term to the driverside fenderwall.

Giving me 5 spots.

Are these the best spots to use ? Or can I daisy chain to include the strut mounts ?

This would be easier and cleaner if they had a dist. block that had one 4ga. in and 5 or 6 8ga. out.

I made my own, it was a cool project, cost me approx. me $50 in materials, and I get compliments on it every time I open the hood. I didn't daisychain anything though, ran an individual 8ga wire to 5 or 6 diff't points into a Stinger distributor block that's zip tied on top of my Optima. I then ran a single 4ga wire to the negative terminal.

If I noticed a difference it was in the smoothness at start-up, but I'd be wary of believing HP increases though.....

yea, those are good grounds, i would also tie into the stock grounding points on the engine. there should be two of them. then also ground near the t-body to hit those sensors also.

I haven't replaced my grounds yet! but will do so soon!. To you fellas out ther I suggest getting NOLOGY Spark Plugs Wires because they have their own built in ground straps! YES YOU ARE READING RIGHT! They have their own ground straps on the spark plug wires! you connect them were your headers are! you will notice an increased HP! & on save GAS!. I have them on my 94 Accord! Every time I open my hood I get complements even by COPS! hehehe They say "WOW DOES ARE REALLY NICE PLUGS YOU GOT THERE! WHO MAKES THEM? THEY LOOK VERY NICE! I NEVER SEEN DOES BEFORE!" then they say "ARE DOES LEGAL?" & I say "YES THE CARB NUMBERS ARE THERE! & THEIR MADE BY NOLOGY LOOK FOR YOUR SELF!" Then they ask were did I buy them & how much they cost!. I know its unbelivable when they ask me does things cause its funny! they stop me for what ever reasons but then they let me go, unless if I was speeding!, but when I'm just crusing they pull me over tell the pop my hood they see that everything is legal that I have the carb # for everything they let me go. I suggest bying them through SUMMIT RACING! its alot cheaper! but you are going to spend about a buck fifty (150.00) thats how much I bough mines for & I TELL YOU ITS WORTH IT! YOU WILL FEEL A LITTLE BIT MORE HP! i GUARANTEE!!. tHOSE WERE THE FIRST THING I PUT ON MY CAR & i FELT IT A LITTLE BIT BUT ENOUGHT TO LET ME KNOW THAT YEAH THEY DO GIVE YOU SOME HP! & SAVES YOU GAS!

Just get the Paranoid Fabrications kit. Won't break the bank and is just as good as the high priced ones.


as far as the Nology plug wires......the wrx has coil on plug, no plug wires.

Fwiw...
- 10 ga. wire - plain 'ol automotive primary wire from any auto parts store - should be sufficient

- don't daisy chain

- run a wire from each of the ground bolts on the intake manifold, near the front on each side (you'll see existing wire looms attached to each of them); other ends of the wires go to the existing ground bolt on driver's fender - where the short heavy ground lead from the battery attaches

- if you want you can add another wire from the alternator case to the same lug on the fender; mine is under the top outboard case screw head (note: it was very difficult to get the screw broken loose w/o stripping the head; very tight!)

- probably a good long term idea to solder the lugs to the wires

- use a dialectric grease (auto parts store) on all the connections; the whole idea here is to improve the overall ground paths to the critical grounds on the engine - long term, hence the grease

The major potential issue here is that the sensor shielding grounded to those points on the intake manifold are then dependent on the conductivity through the manifold's connections to the heads, and the head's connections to the block, and it's connections to the body...and thence back to the battery.

Which wouldn't be a big deal if we were dealing with grounding a 12V hi current connection, e.g. headlight. But these are shield grounds, as well as potentially ground paths for sensors (haven't verified that): low voltages and low currents - which may not reliably pass all those interfaces, especially over time as conductivity decreases (think dissimilar metals - steel / aluminum / zinc plating, galvanic reactions, corrosion over time...).

So adding a clean path back to the battery ground (via the fender lead) can help keep signals clean long term.

Don't bother with strut tower connections, etc., unless someone can give you a really convincing technical explanation of why they might be beneficial...and I haven't heard one yet

Btw, all this was checked out w/ a EE with long term automotive experience. His general opinion is that ground paths are the easiest areas to overlook or take for granted when designing systems...

ive seen 15hp on the dyno. the stock ignition system gives a terrible burn because the coils cant perform at full voltage with the stock ground cables

No need to bump this thread from 2003.
Use the search function to find info on grounding kits and DIY's, there are plenty of threads to read.
