When I showed my car at AROC in 2008 I got a deduct for not having the blue coil and I have had several people tell me that my Marelli distributor and coil are original. Can anyone shed some light on this for me. Thanks.

A picture of what is on your car would help. A 74 USA GTV should have a Marelli coil and distributor. A Bosch blue coil is not correct. No Alfa came with a Bosch blue coil stock. Earlier 105s came with a Bosch coil, but not the Blue one.

You have a MarelliPlex ignition system. Much better but not Concours correct. You have an electronic system now. Original had points distributor and different Marelli coil. I will send you a picture of a correct coil and dist. later today.
Carbs are not correct either. At least not for a 74 USA Alfa. I would not change it to make it correct. Better car with the mods.
P.S. Beautiful GTV.

Spica

Yes I know that is the last thing that I will do after I install the center muffler, stock sway bar, correct ignition and a couple of other incorrect items other than that the car is very correct they told me at the 2008 to never sell it. It is a true USA 1975 not titled 1975 model also per marco.fazio at Alfa Romeo in Italy.

Spiffing the engine compartment and interior up and other things and hoping to to get a good rating at Lexington, OH this July.

I agree with what hotlegs32 has written - your '74 GTV would have come with a Marelli coil with an external resistor, and a Marelli points-and-condensor distributor.

However, what is shown in the underhood photo you posted is a MarelliPlex electronic ignition system. So the judges had a point - that is not the ignition system that was installed by the factory.

I hope you didn't lose too many points for the MarelliPlex - it is period correct and was built by Marelli. Substituting Webers for Spica injection probably cost you a lot more.

where do I get the correct marelli dist & coil?

I found all of the Marelli times two for my Giulietta Spider Veloce but do not know too many sources for non racing or performance parts for 115 autos.

You may need to go to a used Alfa parts source for a Marelli coil with external ballast resistor. If you need a source, PM me. If you need a picture posted of a stock engine compartment from my '73 GTV, let me know.

Also, if you want to be concours correct, you have a Bertone badge on the driver's side of the car. 2000 GTVs only came with that badge on the passenger side. And I'm sure you're aware your car is side marker deleted... an upgrade considered by many due to the huge DOT markers required at that time.

Nice color GTV:)

picture and source

I would love to see a picture of a correct engine compartment and anything else and a source for 115 parts. I have about every source imaginable for Giulietta Spiders both normale and veloce in Denmark, Germany, Italy, several in Great Britian and a bunch here in the states but really green on 115's concourse parts. I race a GTV 2000 and have a street rod GTV so very familiar with those kind of parts but not correct concours stuff.

what is pm me mean?

thanks I have one of those on the shelf the coil

but my guys said it did not work with my distributor do you think with the right distributor it will work or should I send to Motorkraft (marelli specialist) and have redone and then find the rest?

Thanks a lot very nice engine bay

Your Mariplex is an electronic ignition with a matching distributor. My GTV is set up with the original distributor, points and condensor... LMAO! It runs fine, period correct, but probably not as smooth and easy starting as an upgraded car with Petronix (or similar) electronic ignition.

So yes, your distributor probalby won't work with a Marelli coil/external ballast. But if you want it concours correct, then just get a regular distributor. Something like the RML Performance Points Distributor might work... an OEM replacement from Alfa Parts ... or get a good used OEM one when you get the Marelli coil...

I agree with bellagt, but I would have phrased it as: "So no, your distributor certainly won't work with a Marelli coil/external ballast"

Well, an RML (or a 123) would work functionally. But it won't pass muster with the concours police any better than the MarelliPlex did. The RML is built into a Bosch distributor - the Marelli that came on tstahly's car is larger in diameter than a Bosch.

or get a good used OEM one when you get the Marelli coil...
Right, now you're on the right track. APE probably has a pallet load of points-style Marelli distributors, coils, and resistors.

Very nice car, is the aircon compressor/mount off a later one? I've got that one going on a 74 and it's so much better than the junk they put on them originally especially the york piston comprssors. Also is yours the factory with the shortened consol? i've been looking seriously at the classic air package tray mount in the rear for the unit itself. I just want one that works going less than 80 miles an hour.
