1976 mazda 121

Electronic ignition is the best thing since sliced bread. My old 626s used to burn condensors and points
at regular intervals. Changed to electronic and never looked back!

To perform an electronic dissy swap - class 101:
1. Find a Mazda electronic dissy :twisted:

, and buy an electronic ignition coil.
2. Make up a wiring adapter(2 wires with female spade terminals on either end - if you don't have a 2 pin plug handy for the igniter end) to connect the coil to the igniter on the dissy.
3. Line up timing mark on crank pulley, making sure the rotor button is pointing
at No 1 cylinder position in the distributor. (also makes sure you're not 180 degrees out)
4. Remove the old points dissy and throw to the sh*thouse!!!!!!!
5. Line up the timing marks at the gear end of the new dissy - there is a drill mark on the gear and a slot on the casing. Rotor button will automatically line up with No 1 cylinder. Re-install and leave locking nut loose.
6. Install new coil and connect wiring from coil to igniter - the igniter has very small + & - on the side.
7. Start car, set timing and enjoy "point and shoot" timing adjustment.

Total time to convert, when prepared - 15 mins

I think there are two types of GT40 coil as well, so make sure you get the right one! (I think one is the GT40R from memory).

the R stands for resistor which would be the wrong one. He needs to remove the ballast resistor and run it at a full 12V.
a plain GT40 or an SU12 will do it in oil filled or you can swap to smaller transformer type like a HEC715
They will run with the ballast in place but will only be getting around 9V instead of 12.

So I won't tell you I found another MA electronic dissy at another Victorian country wrecker today
- 15 mins of ratting around in the old model distributors section, and bingo, GOLD!!!!! :tu:

There are times when a job that requires you to travel all over the countryside pays off.

Been a while since I checked on this thing, good to see you found a dizzy after all that

Any updates?

jimjams · **Posted:** Wed Dec 07, 2011 8:14 am

yeah i have been working like mad and haven't had any days off but the electric dizzy is in and the car is running super smooth. it was such a good upgrade and anybody with one of these should do it.
outer then that the body is starting to look ratty with rust and so on

got a quote to have the body completely restored ( $25,000 )
so thats not going to happen haha

For $25k you can buy a new one whith all things already done to it im sure thay way overcharge you. In another hand you can spend around $1000 and do most of the stuff yourself in our time it plenty of info how to do things on the net and youtube so do the research and then do what you need to do and you save your car and you save your money. Then you can try to find ppl who can help you with oneoff jobs which too complicated for you to do on your own. So dont gave up on your car coz some one wants to make some money out of you.

$25,000 was a nice way of saying "go away please, we don't want to touch it".

If you're serious about restoring it correctly, then speak with Restoremaz.
I am on a long waiting list to get my 626 done, and am very happy to wait for him
to perform his magic on her!

This also gives me time to accumulate the cash I know I am going to need! :tu:

jimjams · **Posted:** Fri Dec 16, 2011 12:26 am

dont worry not giving up yet haha.
just have to wait and see as everything in my life is changing at the moment.

jimjams · **Posted:** Mon Jan 30, 2012 9:14 pm

ok so i have had the front struts replaced new brake lines and pads and wheel alignment. o and rego.
well my girlfriend and i found out last week that she will have to have open hart surgery before she turns 30 about 5 years from now.
after this surgery she will be unable to have children. sooooo it looks like we need to do some growing up and unless i get a new job that means selling my beloved 121.
now i will have to get a new job within the next few years but that is easier to say then do.
i guess what I'm getting at is what would you guys consider the old girl to be worth.
it is worth saying that jess ( my girlfriend ) does not wont me to sell the car.

Man oh Man I feel for you man. I hope you keep your 121 man but if all else fails God speed to you and your family.

UtahSleeper · **Posted:** Tue Jan 31, 2012 12:20 pm

That sucks aand I hope all goes well.

Why would you need to sell the car though? Usually the trade loss in selling compared to invested isn't normally worth it. Plus, if you own outright, you can park her till money allows.

jimjams · **Posted:** Tue Jan 31, 2012 11:48 pm

there is no doubt that i would be losing money if i was to sell her.
i could keep it but i have no where to store it.
i guess it comes back to money issues if i can find myself a new career that pays well in the next little while then i can keep her and afford to do everything els but i don't like my chances.
and its not like I'm being greedy i would only need 50 grand a year to do the family thing and the car thing but as it stands i make half that.

driving home from work on sunday night at about 4 am the engine developed a metallic tapping noise i pulled over nothing was wrong but the noise was still there so i got off the free way and limped her slowly home.
got home and the noise had gotten a little louder but not by much.
woke up in the morning and first thing started it to take it to my mechanic.
the noise was dramatically louder and it had a really bad miss got to the shop witch is to blocks from my house.
he called me yesterday to tell me he thinks one or two of the rockers may have died and there is no compression in 2 of the cylinders.
needles to say this shouldn't have happened as the engine was rebuilt not long ago.
so he is contacting the guy who did the engine to see what the hell is going on.
not happy!!!!!!
