the ground for the injectors comes individually from the ecm. ie the ecm supplies ground when it wants injector on.

wat i've been thinkin about doin is takin the wire that goes from the negative terminal to the block and disconnectin it and runnin it instead to a metal plate then runnin ground wires from the plate to dif spots on the block. its kinda confusin but i think it might work

not as well as the engine block. use a multimeter . your grounds are probably fine as they are.

my car was ****ed! i never knew grounds were that important...i added 3 wires.. one from the intake man and two from the engine to the body.. the little dinky wire from the side of the engine to the firewall gets old.. plus i got an oil leak so the thing doesnt even work..its covered in **** lol i baught a ground wire kit but you dont have to and i just used the wires. anyone know any other places i shud ground? and when i used a multimeter numbers were flying around.. i couldnt get a stable number.. maybe i dont know how to use it properly..

i read an article in "import tuner" a year or so ago titled "5hp for under a buck!" in the article they used a honda b series block and grounded each coilpack to a metal aluminum plate they fab'd. after dyno, the results were good, added hp and tq across the board. i have the article ill try to scan it sometime.

"Just like most ground wire kits, power comes from where you ground the wires. We found that grounding near the alternator and spark plugs works great but placing them near crank triggers tends to make power erratic."
