I've always wanted an engine grounding kit for my car, but didn’t want to pay $120+ for a couple of pre-fabbed cables/ connectors. After looking around, I thought maybe I could make one just as good as the name brands for less coinage.

So I went to HomeDepot and purchased some grounding connectors for less than $10 bucks.

 

I then went to BestBuy and purchased 10 feet (2 x 5 foot packs) of high quality 4 Gauge copper wire for $38 bucks.

 

I was able to fabricate a high quality 6 point grounding kit for $48 total... :-)

 

Hey, pretty sweet. Im sure a few people may give that a try. Looks pretty clean. Good job!

 

For $10 more and a lot less pain in the butt, you can order 1 from Intense. Good job though!

 

+1 on doing it DIY...do you like to...do it yourself?

LOL - jk, I noticed you have a JWT sticker on your strut bar, did you put the Popcharger into the stock box? If so, teach me how!

 

are grounding kits actually worth it?

 

3.80 a foot for 4 ga...you got ripped the eff off. If you bought online you'd have gotten just as good a quality for <$1.50/ft shipped. Looks good though and still cheaper than a grounding kit

 

I thought I'd make another improvement to this DIY mod... A battery ground... HomeDepot sells heavy duty (it literally is heavy and quite hard to bend) 4 Gauge copper wire and connectors for about $7 bucks.

 

nice job

 

Hey gotchick, that looks pretty cool. Nice idea. I live very much!

 

Any differences are from disconnecting the battery imo. I did it to find out. Not really any difference.

 

I have this planned for the Z. I did it on my mazdaspeed protege and noticed that it stabilazed the idle and there was less draw when turning on lights or using windows, etc. Honestly most of the factory grounding and power wire is junk, and not up to par in most cases. Especially considering the amount of electronic gadgetry we throw into them.

 

what is the effect of this grounding kit ? More hp ?

 

only difference i've ever felt before were in my audio system. night and day difference in sound quality and even radio reception.

i also did a wire from the battery positive post to the positive on the alternator. my subs kicked a lot harder after that. on the Z, i haven't noticed any real gains cept a lighter wallet.

 

The only problem I see here is what's called dissimilar metal corrosion. You get it from using steel or aluminum connectors with copper cables.

 

here is the one i did myself...

good job by the way, i like your connectors more...

Do you think since this is in the DIY section that you could maybe show pics of the different points you used to connect the kit? I only say his because I'm pretty sure most people know you can do this. Its not too hard to figure out, especially if you know what a grounding kit is and that most descriptions of them use 4 gauge wire. The only difference is that each brand has a set of different wire lengths and a place to route each wire.

 

+1

lengths should be mandatory information for a DIY for grounding kit

 

Does anyone know which points specifically are needed to achieve better lighting? I would like the brighter headlight benefits without wires running everywhere.
