Bottom line:



HKS system = $40 shipped. (Labor I do myself)



Custom system (12 Gauge wire, 7 grounds) = $150 (Labor included)



Is the HKS system going to make my car run any better or add any power? I don't care about "blinging" my car.

 

I saw a dyno of the grounding system. It was supposed to add 5 hp in the driving range. Did nothing for top end power. You could probably make the kit yourself by just buying parts from your local hobby shop.

 

For $35 shipped, I'm just gonna buy the kit.

 

wile_e_coyote---Do you want to know what a few companies in Japan said about it? Just for fun. Yes they all make the kit.



"It does nothing"



"if your car is old, your grounds maybe weak so it will help"



"I never used them and everything is fine"



"Best thing I ever put on our RX7s"



Also yes this is no BS, when I had a miss-fire, before Dragon went for a shitty ride and the engine blew, i went to several companies to see which was the best and compared with the price. FUNNY HUH?



Anyway, like JSPEC Said:



What I did is where the engine is originally ground to the firewall, I sanded it and cleaned it up, better contact surface, ran a wire from there to the engine, and also another wire to the Alternator (it plays with the most current). I wouldnt say there is anything you can feel in the way of HP (some claims but hard to say I dont dyno much) but it did smooth out the idle a little, you will understand that the longer you own the car and understand it, but it did do that. I also had the idle stick at like 1500rpms after I rev it and then slowly drop, after putting the wires in, it didnt do that anymore it reved and dropped to 900rpms where I have it set.



Either way good luck.

 

12 gauge? that is some pretty dinky wiring. I have 2 guage going to my firewall and intake manifold.



helps with my 3800 rpm hesitation

 

12 gauge is very tiny for cars i would think, its what we use on our hobby class R/C's to connect the battery and motors.

 

I meant 2 gauge.
