TR6 123Ignition for TR6

Share this page

Alec,

I suppose I had two big reasons for changing out the dizzy... The biggest, as I've said before was just because of my frustration with my other dizzies and the quality of the aftermarket parts for them (rotors: great example). The other reason weighing in almost as heavy as the first is performance. I'm running a pretty stout engine with 10:1 compression ratio, so in my case the extra umph from the ignition system is warranted. The car seems to run pretty well with the factory Mallory advance curve (24 degrees at 3100rpm).

As for the tach, some might see the conversion process as a big negative.. and yes it ain't cheap (I had my conversion done by APT). However there are a couple of big upsides: My tach is rock solid now and dead accurate. No longer does my tach bounce around when I shift hard and under hard acceleration the tach doesn't drag. A typical mechanical tach can show 500-1000 rpms less than the engine is actually running under hard acceleration.

I don't want everyone to think that this stuff is the end all be all. It isn't for everyone. A stock motor really doesn't need this stuff to run extremely well. But IMO, a modified engine has lots to gain.
 
OKay, well, I have been looking for the Mallory set-up on the web to find our more about it, but can't find a web site. I'll keep looking. My mechanic sets up Brit cars for racing, and I haven't asked him about ithe Mallory specifically. I need to stop bothering him for awhile. I wrote to him about this, and he told me the car was running like a new one at this point, and he wants to wait until I come back to the U.S. and drive it for awhile before he does anything more to it. He has been using it as his daily driver so he could get it just right. I need to listen to the man.

...but it never hurts to do a little researh...ha!
 
If it is for a TR6 i have one. Get it at Performance Parts something or other. I think it the one for the Jag??
 
Dannagy,

This is from a previous post of mine. I would never buy something like this from one of the big Brit parts supplier.

Here's what I did: I got the distributor at https://www.centuryperformance.com. I was referred to them by some fellows at 6-pack.org. I ordered Mallory part number 4567801 for $320.00, which is the Mallory Unilite without vacuum advance. The next day the guy from Century Perf. called me and told me that the dizzy was on nation-wide back order for weeks. However, he did have the dual-point model in stock (part number: 2367801) which is externally the exact same distributor as 4567801. He also sells the Unilite conversion kit which then makes the dual points model identical to the Unilite version. He even converted the dizzy for me. Grand total: $240.00. Not bad considering Moss sells the Unilite for $523.00.

The Mallory does not come with a dog drive, you need to take the one off your old dizzy and have the shaft drilled for it. The Mallory comes with nice instructions, so I dropped it off at a local machine shop to be precision drilled, I had them orient the dog drive (in relation to the rotor) the same exact way the old Lucas was. The charge was $40.00.

The only charge I wasn't expecting came when I read that the Mallory requires a ballast resistor. Since I wanted a new coil anyway, I ordered a Mallory coil, part number: 29450 which has an integrated resistor. I mounted it on the flat spot on the fender well right underneath the master cylinder.

All those thinking about converting to 123ignition and who do NOT want to convert their tach to electronic and who want the real original look under the hood but all the advantages of the 123ignition, have a look at this website.

Best regards
 
Thanks for sending your setup, Shannon. That really lays out what to do.

I saw a fuel injected TR6 on YouTube. I want to check that out, too.

So far, I like Eric's post about the 123 modification. I guess whatever I do, I'll plan on a thousand bucks.

Right now, the car is a bit torn apart so Ihave time to consider all the options. -d
 
I know this is an old thread. But remember the 123 Ignition manages the advance curve electronically. Gives four sets of four advance curves for a total of 16 selectable curves and has no springs or weights to wear out or stick. Additionally they have added a new fully programable version for those that wish to plot their own advance curves.
