[Guide] 2T, 3T-c & 18R-c Electronic Dizzy's. "How To"

[Suavemechanic]

Hi spotted that last night and wondered the same thing !
any one tried one ?

[blanky]

the blue ring is made from truck air line really obvious in this photo

Is there too much mechanical advance without the blue tube?

Is there too much mechanical advance without the blue tube?

Hmmm.. "Yes & No"

the clear fish tank tube is the same size as what Toyota used back in the day..
hence why i stated it back on the 1st page..

it is a dampener for mechanical advance, & when missing, you will find exsesive mechanical advance..

if you need more advance there are a few different "rotor cam's" that can be found or you ca use a file to open up the gap..
but remember that the softer fish tank tube is a dampner ..

Thanks for clearing that up I have the gizzards of two 3T dizzys and they are slightly different - one has reluctor vanes twice as thick as the other and one has 8.5 stamped on the rotor whilst the other has 10.5, I'm guessing this stamping is to indicate the degree of mechanical advance. Although, one has the rotor cam soldered up and filed so it seems someone was playing with advance curves.

Also, does anyone know if the VR sensor??.. err magnetic bearing plate thingy inside the dizzy.. are available new? I had a quick search online last night and didn't come up with the goods.

Cheers, Jess

"yep" you can find 4 x different advance deg' i've found 8.5 , 10 , 12 & 14 .. "yes" this stamping is to indicate the degree of mechanical advance ..

Q:- magnetic bearing plate thingy inside the dizzy .?
A:- never seen one new & may of gone the same way as the clear tube thing we now use the fish tank tube, just no longer made..
now to the bearing plate thingy.. "Rotator plate" ..
just wash it out with a tin of degeaser, blow out with air, wash out again with degreaser, (you may need to do this many times) now it should spin freely, so pack it with Hi-Temp' grease & remove excess..
this is all i've done on the over 100 units i've converted..

im wondering, is it worth going to all this trouble making this electronic dizzy then buying the little modules that replace the points that "convert its to electornic ignition"?

"YES" just find the RA60/65 21R or 22R parts .. it's easy ..
the electronic set up is the best stock part you can find, & you will not get "Point Bounce" at high rev's & no more Burnt Points ..
all the info is on the 1st page & what/were to find each part in what model of car .. pick & pull are fun ..

Hey guys, this is my electronic ignition conversion on a 2TG/3T hybrid:



Car broke down *again* and it's still not going. Replaced all the dizzy innards from a 21RC RA60 dizzy. Rotor cam had 11 stamped in it, and I used the little blue plastic end from the crimp on electrical spade terminals. Nice tight fit and you don't even need to cut it, just press on

Rest of the ignition is a new coil, new BIM024 module (HEI brand), dizzy cap & rotor button. Leads test about 1000ohms/30cm. Tried a spare set and it seemed to make no difference.

So I've put it all in as per above pic, and set the timing by removing the plugs, putting one into no. 1 lead and earthing it with jumper leads to the block. Timing light reads ~16 deg advance at ~200-250rpm crank speed, so I'm pretty sure the timing is accurate enough to at least get a cough, splutter or two, but all I'm getting is occasional f**king loud backfires through the exhaust, not even a little murmur of life. Spark from the coil is strong - it jumps a blue spark a good 10-12 mm from earth.

Started sussing out the fuel delivery after going over the ignition. I have a mechanical pump and a push dial low pressure fuel reg and it sorta "dribbles" fuel from the fuel line while cranking. Checked the fuel bowls of the DellOrtos and they were just over half full. Still not certain it's getting enough fuel, so I cleaned up a spare 3T mechanical pump to try, but I'm not sure if the lobe on the 2TG auxiliary shaft is compatible with the 3T pump. Short of that it will be in the shed for a couple weeks until I can afford an electric fuel pump, new reg & a fuel pressure gauge.

Anyone got any bright ideas to why she no start up?

Cheers, Jess

you may have your timing is 180degress out, it sounds like you had my problem just recently, take out no 1 spark plug and put your palm over it an wait until your feel air trying to escape, which mean its on the comp stroke of no.1, then put a long screwdriver down the whole and rotate it until it get to TDC (or near TDC) then take out the dizzy and line up the rotor with the no.1 on the dizzy cap or near no.1 one and slide it in, it will move slight as the helical gears mesh with the cam, then pop the cap on, also double check your firing order 1-3-4-2 Clockwise, and make sure your not running a ballast resistor as those gt40 coil dont need one (gt40R does), unplug the vacuum advance so you can turn the dizzy more.

then get someone to crank the motor while you turn the dizzy until it fires, if it doesnt fire then you've got bigger problems, also do those electronic ignitions need a condensor?

cheers,

Q:- also do those electronic ignitions need a condensor?

you will find the answer as "YES" & is on the 1st page 1st post & in the wire diagram i supplied

noise suppresor + plug & 8inch of wire. ST141, SV11, these have a single plug ( Blue )
noise suppresor or as you have called it "condensor"

Don't know how many times I've done it I should've learnt already.. haha it was 180 out, so fixed that and was still a bit dodgy, so I swapped the new generic $20 BIM024 module for an old genuine bosch one and it went okay. Still has a miss up the top end under load though, so I may try the 21R ignitor with my GT40 coil and see if it clears up.

Hey everyone, A quick few questions. I recently got a 21R dizzy, Coil, igniter and noise suppressor thing from an RA60. The car I want to put it on is my 18RG RA40 coupe which already has an electronic dizzy made from modified 4K parts (Thats what I have been told, not what I have done) but it's still using an old coil and a resistor? I have taken the cap off and it is definitely electronic. I tried installing the RA60 coil and igniter and the car wouldn't start, The tacho didn't even budge. I'm about 80% sure I got all the wires correct, Could it possibly be that the coil or igniter themselves are buggered? If the coil or igniter is buggered, Is it normal for the tacho to not budge when the engine is turning over?

Another question, Does swapping the coil and resistor from an 18RC for a coil and igniter from a 21R improve the spark any more or should I not bother as I don't have to worry about points anyways?

Hi, i was wondering, which vacuum advance unit people have used?
The original 18r vacuum doesn't fit on the 21r electronic part, but then the 21r vacuum has 2 outlets?
Thanks in advance.

"Yes" it does ....!!!!!!

you need to file / linish or grind the back of the "Y" to get it to fit under the 21R parts..
Hmmmm... i should do a pic' for this..
Soon if i remember..
but should be very soon as i have a dizzy to build for a toymoder .. so soon..
