Electric Dizzy 4k

[the Db king]

ive got a denso electronic dizzy out of a 4k-u engine it has i ignitor in the dizzy with 2 wires, 1 from the pos and 1 from the neg of coil and 2 wires goin to the magnetic pickup,

now the prob that i have is that the ignitor has craped itself and wont give a strong enough pulse to the coil.

 

am i able to use a external ignitor from a celica or something like that to do the same job.

 

before you say just get another internal ignitor, because ive tryed that and the only people that had any idea what it was were toyota genuine, and I'm not gonna pay $376 from japan for something that fits in the palm of your hand out of a 20yr old dizzy.

 

hope to get some good news on this,

cheers, ash

Went through two on a good hp motor.

 

Points went back in and never had another issue.

ive got a worked 4k with 85ish hp, and it has idle probs since day one with points, i put the electronis dizzy in and it ran for about a min and then craped out, but in the min it idled like a dream, and would like to try the electronic path

simple answer is yes, most Toyota igniter's are interchangeable, where the problem is, is the coils, use a denso coil and not some aftermarket piece of crap,(GT40, Bosch) also check on the coil to see if it needs a ballast resistor or not, this does make a difference.

 

we have had one in the rally car for years and has NEVER given a problem.

they are worth HP, better spark, more reliable than points and better control of timing in higher rpm engines.

 

my 10 cents.

I'm using a lil coil like what vn v8 commodores use ( i think its a denso) but bosch gt40s have a much higer resistance than the denso ones,

 

can someone say that a bosch ignitor of most comon dizzys use will work, thay have pos and neg coil inputs and 2 from the pickup. just hoping that someone has had a posivite outcome of what I'm trying to do

 

ballast resistors are used in points setups to lower the voltage for the points to handle.

 

cheers all, ash

To put it simply there are 2 basic types of coils first points ignition and the other electronic ignition they have different windings they are not interchangeable.

 

there are many different voltage coils.

The voltage is usually stamped under the coil and sometimes weather to use with a ballast resistor, the voltage of the coil really doesn't matter as long as the correct voltage is fed to it.

 

And always remember to earth the base of the coil otherwise a spark must jump there as well as the Spark plug.

Haven't had a drama scince I put my electronic dizzy in..

[KE30_KE35_KE55]

Electronic is definitely the way to go,

 

 

on another note Bosch has stopped manufacturing some of its point range, others will soon follow.

I would suggest anyone who plans to keep a points ignition stock up why the price is still reasonable.

Hey guys. I just got a hold of an electronic dizzy for my 5k, but i need the all the wiring, ignitor box and any other bits. Any one out there that can help out would be much appreciated.

 

Cheers

it works, ive got electric ign in my 4k :( .

 

i was able to use a ignitor off a bosch dizzy (like the ones that are on 4ac's) hooked up the feed from the pickup in the dizzy and ran the wire to the inner guard to the ignitor, i just had to put a ign realy to the coil to make sure there was 12volts to the coil.

 

so there is a much cheaper way to get them goin, and they throw a huge spark,

Incorrect. I'm using a ballast resistor still with an electronic dizzy as a pickup for an ECU. That goes back into a M&W ignitor to fire the coil.

 

Most older cars run 12v to the coil when cranking, and 6v while its running. The ballast resister does this drop in voltage.

Only real important thing is using an appropriate coil for weather you have a BR or not. GT40 for example don't need one. the GT40R however does.
