Thread that combines all my car threads

Just a thought, but it might be an idea to put some heatshrink on the metal spades too?

So did you use a resistor like some people suggested overseas? From all the research I did there didn't seem to be a definitive answer as to whether or not use one...

[mk3pete]

thanks for the replies guys its really not too complicated when you think about it
i just went to extra lengths to make sure nothing goes wrong

from what i have gathered the only reason you need a resister is to protect the coils from earthing to the car
the coils on a normal car switches on via the positive terminals
on vws they switch via the negative
if they are earthed to the car that means they are constantly on
so they will just overheat and blow up
i didnt end up using one because my icm was good
for those who would like to know if you decide to use one you need a 1ohms resister rated at 225 watts

the reason why people have trouble with blown coils is they have a bad icm
(ignition control module)
basically whether or not earth is leaking through to the contact points on the icm (each coil 16 34 25)

the only way to tell if your icm is good is to use a multi meter that can read in solid state

my mates an electrician so he tested it for me

heres my finished job




and my old coil pack

yep just need to get some it was on my to do list

[mk3pete]

so far no worries yet guys
my car actually has some balls now
anyway highly recommended upgrade especially if you need to replace the standard one

[GoLfMan]

nice job there Pete

[MattyT]

I dont really see how ignition upgrades on a stock engine are going to produce any more power??

Still, it this IS comparing it to our dreaded coilpacks. And good to hear that its running well for ya!

nah this wont give you more power
i was just saying my power is restored because my old coilpack was stuffed

[MattyT]

Ahhh i see

[Mrk_Mickey]

Sorry if I've missed it, but how much did it cost in the end?

hmmmm good question let me see
100 for each coil i bought them locally
160 for leads shipped to my door
130 for bracket shipped to my door
i could have made one but i couldnt be bothered

[Mrk_Mickey]

Mmm, see that's not too bad for the setup! I considered doing it because my coilpack is brand new hehe.

yay these arrived today

.72 5th Gear for 02A/02J Transmissions

http://www.autotech.com/images/products/gear_72fifth.jpg

For the 02A/02J gearboxes found in G60, Mk3 VR6 and all Mk4 models, we offer a tall 0.72 ratio gear pair. Again, these are Factory gears, assuring high quality. The stock fifth gear ratio in a VR6 or G60 is usually 0.84, so this taller pair drops a healthy 14% off your rpm for the same speed. Comes with two new Factory gears

[MattyT]

Now thats a peice of gear I'd be real keen on seeing how it works out for you. I've always thought the vr6 revved too high at fwy speeds.

[Mrk_Mickey]

Sorry for the no0bity of this question, but I have to ask cos otherwise I don't learn!

If the gear ratio (0.84, 0.72) is LOWER, it will go to higher speeds at the same rpm? Ie, 0.84 gear at 100km/h is 2,800, but 0.72 is like 2,500?
