Help with Ground Wire Install (Searched)
Help with Ground Wire Install (Searched)
Hey there, I recently purchased one of those universal ground wire kits for my 92 240SX, S13. I, of course, received no instructions for the kit, and I really don't know where the ground wires connect to, lest I wouldn't be asking. I would really appreciate some help in locating all of the grounding points in my car, via picture or a really good explanation (I know the majority of the parts of my engine). I would really appreciate the help and BTW, they are a proven cheap one horse to the wheels mod, and for $20 I couldn't go wrong. Thanks a bunch.
i dont know if those kits re-ground ALL of the grounds or just the big ones but in any case.... you have a battery ground(the negative terminal) right under the batter tray kinda on the fender wall, and the intake manifold also grounds there. there's also another ground between the battery and the strut tower for y our ecu wiring and a ground on the head to the firewall, if your facing your motor its on the upper right hand side, near the corner of your valve cover. i think that covers it unless i left something out.

I question the effectiveness of those kits. 1 hp mod? You do realize that dyno runs vary from run to run by 3-5 hp usually, even if you dont change anything at all, and thats on a super consistent engine...I know this from LOTS of dyno experience.I am just an eternal skeptic I guess...but it doenst hurt to add more grounding to the system.
All you have to basically do is connect everything together. Find threaded holes on the engine/intake manifold/transmission or whatever you are connecting to, and wire it up. Use grounding points that are conveniently located for the wire lengths provided. The main connections you want to make (that already exist anyway) are battery negative to body, batt neg to engine head, batt neg to block, block to body, head to body, head to block, head to intake manifold, etc... Just connect everything together, be a little creative. Make sure that you get the head especially, thats where your spark energy is grounded. I also recommend paying a lot of attention to routing and securing the wires so that they are not just flopping all over the place.
