Just recently purchased a earth circuit or grounding kit for my 240sx, when the package came. it didn't came with a diagram of all the grounding points for the 240 sx. :wtf: i bought this off of ebay for 40 dollars and i thought it came with instruction. my question is, does anyone have a diagram that show different grounding points located in the engine bay? :confused:

If you wanted to throw away $40, you should have given it to me.

I see these for sale for 240s everywhere, so it only makes sense that people would just start buying them up. Not only does this do next to nothing for your car unless you have an electrical problem, but you could have made one for $5 with some car audio wire and crimps.

Link us to the page. Chances are its just a universal and will say that in the item description. Did the actual auction page have a name like this " Hyper ground kit 240sx 200sx probe" or something like that?

And a ground is a ground is a ground...

Attach is to a point on the chassis where the paint has been scraped away so that it makes good constact, then put a wire on either side of the head, one on the intake manifold, etc...it really doesn't matter.

Come on guys, Import Tuner saw 12rwhp from one, so you know it's good. Even though they forgot to mention they did a tuneup, oil change, and adjusted the timing too.

Grounding kits are by far the gheyest thing ever to come out, even worse than those 'intake resistor' mods that people threw thousands of dollars at a few months ago. Shorten and reground your OE battery ground and you'll get the same results. Then you can sell the leftover wire for a BK meal.

grounding kits have been dyno proven time and time again to work well, especially on an aging car like ours. turbo magazine just did a dyno on the new evo and got something like 8whp. did you waste your money? yes you did. is it really hks? nope its fake. what should you have done? you shoulda done what im doing and used some welding wire and made your own kit...

If I had good marketing outlets I could shit in a box and label it "Shit in a box for 240sx!" and people would buy them up and magazines would test them and claim a 5hp gain.

The grounding kit is actually a nice cheap mod. Let me tell you why. Most 240sx's I have come across show high resistance grounds on the sensors. (Most Nissans have shitty grounds in general). Nissan actually tells you to strap a ground into your MAF sensor ground and tap directly to the battery if the car has intermittent problems. Not kidding here. It is a factory fix.

Now to prove that the grounding kit is not a bunch of bull (like The Roman likes stating) I tested my car's grounds back before I made my kit. I saw voltage drops of .4 volts, .08 volts, and even .7 volts. Anything over .5 is not good for your charging system (Alternator, starter, battery). (Voltage drop is how much voltage you are losing due to a high resistance) So I got some nice Monster Cable 4 gauge wire, and battery terminals, and went to work. After I was done, I checked the connections again.

Alternator= .01 voltage drop
maf= .02
starter= .01
chassis ground= .00
wire harness ground (on both sides of engine bay)= .01-.02 varying
all the ground points in the car showed a highest of only a 2 millivolt drop.

My Alpine stereo does not dim whenever the bass hits, the music is cleaner and louder, my headlights don't dim when I step on the brakes. My engine is noticebly smoother, and what seems like a bit more power. I'm happy with it overall.

Here's where you should tap if you're going to be doing this....
chassis
block
head
tranny
firewall
computer ground on both sides of car
intake manifold

my grounding kit is different from yours, so here is the link http://cgi.ebay.com/ebaymotors/ws/eBayISAPI.dll?ViewItem&rd=1&item=7915445936&category=6763&sspagename=WDVW

Nightwalker,

That's interesting. My headlights dim when I hit the brakes. My rpms go down too so I just thought they dimmed b/c of that, not grounding issues.

So what do you do if the battery is in the trunk? I was just planning on grounding the battery to the chassis somewhere in the trunk area and grounding the engine directly to the chassis.

If your battery is in the trunk, use the chassis as the major grounding point. Also, you want to bring the grounds back there, and you do not want to creat a ground loop by connecting the grounds elsewhere other than at the major point.

I made my ground kit. It's the same concept as your ebay one.

Also, stay away from the distributor.

Nightwalker-can you post more pics of your ground kit? And be a little more specific about where you ran wich wires where. (from what,to what) please. I don't mean to be such a newb....sorry. Also, from the looks of your pic,you are running the OEM negative battery wire,and a second one,right? Where is the second going to?

thanks

Why do you say that?

here's my cheap-o MS paint drawing. This should spell everything out. By engine grounds, I mean the harness grounds. Check in the corner, that's where the harness grounds are bundled up. Also make sure you scrape off paint whereever you are going to tap the grounds to. You want the best metal to metal contact.

of cours they will say it got 12rwhp!..so people can buy the product!..they will always show the best results..but the fact is..becuz that car got "12rwhp" doesnt mean ull get it..ull mayb even get 1rwhp

the fact about grounding kits is only help at a certain RPM interval say 2500-3000...and thats about it..so little that u wont even notice the difference

if u want a real good grounding kit, go to ur local audio store and buy 0 gauge..ur new ground wires

Welcome to sarcasm guy. It was a joke. Why would I make the above point and then bash the hell out of the concept in the same post?

HAHA!! Holy shit man you're right!! Hell put me down for the group buy!! I could use that extra 5hp....

Seriously though the only thing you're going to improve is you're music quality(louder & clearer), you're headlight brightness, and your idling will level off a little (not be so erratic if it is already) You will not get major power gains, you will not beat that SPEC-V now that you have a Hyper-Ground kit, and you will not get 12whp from the aging KA!!

You can and should mount one of the wires to an alternator mounting bolt, one to a valve head bolt, one to a tranny bellhousing bolt, one to a starter mounting bolt, and one wire directly to your neg battery terminal. Those are the basic grounding points feel free to add more if you feel the urge to ground the shit out of everything. Really not necessary though. Oh and the grounding bracket should be mounted to the chassis somewhere, either on the firewall or the strut tower area. Just somewhere easy to access. Not that hard really.

Whether you spend the 40 bucks (easier if you ask me, less mess) or go get the wire yourself and cut your own to fit they all work the same. Really the only reason I got mine was to dress up my engine bay a little more. That extra red gives the bay that little extra touch.

go to home depot and buy some wires (i bought 8 gauge, should be sufficient for ground), that's what i did...
and it only cost me like a buck for 4 feet...

improving teh effiencency of your cars electrical system doesnt hurt... if it does help. I wouldnt mind doing this myself.
