Pertronix Ignitor for a Marelli distro

Hi gang. I'm not sure if this was brought up, but it looks like Pertronix now has an Ignitor for some more Alfa's with Marelli distributors. The part number is MR-LS1. It lists it as a lobe sensor module.

I was just wondering if this would work for my '74 GTV with a Marelli distributor. The online adobe.pdf parts sheet lists a S166B for a 69-73 GTV, but aren't S166B's dual point distributors? I could've sworn I only saw one on my Marelli unit.

Thank you in advance.

Hey Ham! I found out something for you. I called up Pertronix just now and for your car, you're going to need part # MR-LS2 for a s-103b distributor.

Good luck!

Sorry that you had to answer your own question, but I appreciate the info. When I went to their website it only had the catalog for 2005. With this new part number I may save myself the expense of a new distributor.

How much? You gonna try it? Let us know how it goes, I suspect that the advance plate will complicate installation somewhat. Sure would be nice to have a Marelli distributor that you don't have to remove from the engine to adjust the points (what a terrible design). Maybe I won't just toss them in the trash now.

I'm calling around for prices and I will let you guys know.

Update: I tried ordering a unit from Summit Racing. No luck. Gonna investigate some more.

Update: I placed a special order through Summit. It took a couple of phone calls back and forth from Pertronix. Pricing was about $74 plus shipping, which ain't too shabby. About a 3-4 week wait. I'll play guinea pig and let you all know how it goes. If you have any trouble ordering, give me a holler and I'll give you an extension to someone at Summit and he should be able to take care of you, as we straightened out the knot today.

In the early seventies I put a Piranha ignition in my 71 Spider with Marelli. This was one of the early solid state systems with optical trigger. The shutter wheel was in two pieces and wasn't too difficult to install. Did it with the distributor in the car. Longevity of the system wasn't that great though.

73gtv,
I did the same on my GTV and at the same time and it's still going strong. What failed on yours?

The thing to check when installing an electronic "kit" on a Marelli distributor is whether the distributor body itself is worn. If the bushings in your distributor are worn out, even the best electronic conversion will not give you an accurate spark.

Thanks Joe for the tip. I'll make sure to give it a good look over once the distributor is out.

Very interesting.

I have a Marelli S145C distributor in my spider and now I know that there is a pertronix ignitor for it (at last. Two years ago pertronix said me that they didn´t have in mind to make a kit for this distributor).

The answer is: Where can by this kit?

I am in Spain, so I need a company that admits international orders.

You can try the bigger companies such as Summit Racing, which is where I placed my order. They still haven't shipped it yet, but I knew that these Ignitor kits are new to production so it'll take a while to get them out in the market. I don't know what Summit's policy is regarding Int'l orders, but it doesn't hurt to ask. If you have a MasterCard, AMEX, or any of the other worldly accepted credit cards, they should be able to place an order for you.

If you absolutely cannot find a place that'll ship it to you, give me a buzz. I'll do it for you, however you would have to pay for shipping to my place AND overseas. Let me know.
