I decided to build one myself using 4ga power wire from a local stereo shop. Cost me around $20US in total (which sure beats $250 for the ralliart kit). If you have even the slightest technical ability, you do NOT need to buy a grounding kit! The only problem is that this thick wire is difficult to crimp, and takes some patience to solder the ends properly. You may elect to use 8ga wire.

For the $ spent, Its well worth it :

* way smoother idle.
* Voltages are up from ~13.4 to ~13.8 Volts across the board.
* Engine feels smoother and pulls a little harder in the mid to upper rev-band.
* A/C does not suck as much life out of the car esp. when driving on vacuum. In general the car is more pleasant to drive off boost.
* I notice it pulls out of intersections easier with my usual compliment of 2-3 passengers.
(some people report brighter headlights, i have not been able to test this yet)

This is an idea of how it is attached in my car (i don't have a digicam yet, but I will redo the pics with the ones from my car when i get one this week) :

fender factory ground point to neg battery terminal :

head to intake manifold & then to firewall factory ground point:

firewall to passenger fender

p.s. :
* i bolted the wires to the rear engine hoist as that bolt on the head is hell to get to.
* cleaning & sanding off the connection locations a bit is a good idea.
* i did not ground the tranny side of things, as i ran out of wire, I may do this however.

As an alternative to "BUSHLLIT" audio cable, welding cable has similar performance.

It is better to crimp the terminals (lugs in US) as soldering can make the termination brittle, hydraulic engineers also have suitable crimping tools

:fftopic: how do you keep the engine bay so clean

I'll reply to your PM later

Hehehe ... well those pics are from a US dude who did the mod when he just got his car. My Engine bay is nasty.... :blush: :blush:

Welding cable would work nicely.... but the audio cable was easier to find & actually cheaper! (don't ask its Jamaica.. prices are all upside down here :coolsm: ) I ended using a bolt cutter to crimp the ends TIGHT and then soldered them for extra security.

but the real question is, did you actually notice any difference ?

Heheheheeee :D

I too was sceptical at first....

No earth shattering improvement, but well worth the $20! Besides, the factory grounding points on the fenders & firewall are anaemic & were slighty corroded @ 16K!

This is the factory wire that attaches the firewall to the intake manifold.... tiny

(thats the standard size match stick)

i made one too.... it looks great but thats it-as expected-no performance gain or difference in the operation of the motor.

if you have spare time and 30euros to waste in engine bay customize then find a nice type of cable from a car stereo store and do it!!! i really like it....

if you can find me a place for host i've got some pics

Thats the interesting thing.. some people report no difference, some folk notice a difference.... we all know that not all evos are made the same, maybe that accounts for it.

Maybe the difference is down to the cleaning of the contact points in the fitting process :)

it could be a difference on the dynno - smoother curves - but in the road it's not noticeble.... my system has 9 conctact points to the chassis and motor with very careful installation so if something sould be added in the car operation i sould get it....
don't get me wrong , i'm not againts this kits but i think that they sould not advertized as a "performance product" and defenatly they shouldnt cost 200 euros just for the brand name(hks...).....
