Electronic Dizzy??

[Screwy]

Hey all,

Just got a new 308 Holden V8 fitted to the Patrol again ( since the other went met with the devil ) and i got it all tuned up ( duel fuel ) yesterday. The guy who did it told me i have a cracked diamphram in the dizzy vacuum advance unit. He adjusted the timing to suit but i want to fix it.

It will cost me $60 for a new vacuum advance unit to get fitted to the standard dizzy OR i can spend $200 and get a complete electronic dizzy with cap and coil and everything.
Wat are the pros and cons of going to Electronic dizzy?
Or should i stick with astandard dizzy and get a new vacuum advance unit?

ALSO, i got told to use a Ford rotor button with this electronic dizzy in the holden, can anyone give me any info about this?

cheers

If your handy with adjusting a points dizzy then stick with it as they need to be real bad to not work at all out in the middle of knowhere.
The electronic dizzy is fairly reliable and usually only fails when the Ignition Module burns out. But they are not very expensive new and are easy to replace so carrying a spare is easy.
The only reason you use a ford rotor button is so you can use the small early dizzy cap.

aahhh is the rotor i need out of a standard 4 litre like an EB???

also i thought u just needed and electronic dizzy and the appropriate coil.
where does the ignition module fit in?

Its usually a V8 ford rotor botton that is used. There may be another set up im not aware of.

The ignition module is on the side of the dizzy under a tin cover.

got ya thanks.

Is there any large bonusus performance wise with an electronic dizzy?

They do supply a cleaner spark but unless you are going to rev it real hard all the time a points set up will be fine.

I run a points dizzy in my 3.9 and it had an electronic one in it originaly

[Screwy]

ok ill give it some thought.
thanks ruff

I have an electronic dizzy on my 253 and I cant say I noticed any huge gains.

I had to change to the smaller cap (due to space restrictions) but am unsure as to which rotor it has

[Screwy]

yeh, space restrictions is y i have to go back to the small dizzy cap and apparently the holden one wont fit in there, so a Ford one has to be used........
Apparently there is a difference on LPG. It runs much smoother on LPG. Is this correct?

Never have to change points or condensor ever again..... set and forget

I ran one with the 253 and then again in the 308. never gave a single problem and worked real well in river xings, whereas the old points dizzy gave heaps of probs when ever it looked looked getting damp......

worst thing about the electronic dizzy is the module....if it goes ya stuffed, so carry a spare.

If you change over to electronic make sure it hasn't got an optical pick up in it.

Hall effect pick ups are a lot better and more reliable.

I agree, ease of maintenance is a huge benefit Although I didn't get the extra 120hp I was hoping for

its much better for gas setups as it prodvides a stronger spark and gas will work much better with better spark thats why newer cars play up n gas when you have faulty leads or dirty plugs they tend to back fire and miss. also the electronic dizy wont break down in the higher revs like a pionts one will

[80UTE]

Talking V8 Dizzie's the Bosch electronic dist has a different size shaft and locating system for the rotor button than the points style dist. All Holden factory electronic dist used the bigger diameter cap to prevent x-tracking of the spark. Ive used the early Holden cap with the Ford rotor button the Ford cap will fit and is very similar except were the spark plug lead fits the cap the Ford has a bigger boss and lead boot to suit. With the early Holden cap an early Holden lead set will fit fine. Ive had custon lead sets made up by Ignition Developments and he recomends the Holden caps as there are better boots available for the smaller boss Holden type caps.

don't forget to include the price of getting the new dizzy advance curve adjusted to suit your motor.

Go the electronic,

Better starting, economy, better in water, I've swapped the dizzy on 3 different Holden 6's and never regreted it and kept the original rotor, couldn't see why the V8 would be different.
