Sam,
Are you sure the crank pulleys of the GTV6 and the milano are the same? Somehow I thought they were different. Though, I haven't looked at a GTV6 crank pulley recently...

Jes,
The older ones are different, but the one on my '86 and a friend's '86 are the same as the Milano, they also have the Milano cam covers, but I don't know about the flywheel. I know there are issues between the older GTV6 flywheel and the Milano, I don't know if the '86 GTV6 has the Milano or older GTV6 Flywheel.
This is the pic of my GTV6 engine, not a great shot of the flywheel, but it is the same as the one's earlier in the post.

That is THE question. My understanding is that it won't work.
However, I was thinking that perhaps a pulley of a Motronic 75 would be a straight bolt-on AND fit. Anyone?

Jes,
I am running the 2.5L pulley, AC, alternator and water pump on a 164 3.0L 12V. They all line up perfectly. I intend to use the 3.0L pulley and crank sensor when I add spark to MS on that motor.
Have a look at the 3.0L motor in my 3.0L conversion document in the Technical section. You'll see it all lined up. I don't have power steering but you can see the spare pulley groove. I don't see why the 3.0L pulley won't fit the 2.5.
I have the 3.0L pulley and a couple of spare 2.5's so I'll bolt it on and see how it looks if you think that might help.
I think you will also find the castings are on the 2.5 block ready to drill & tap for the crank sensor, but I'll have to check that to make sure.

David,
Thanks for the info! Note that in my case this is for a 3.0 V6 (US Milano Verde), not a 2.5 GTV6, or a 2.5 V6 Milano. My verde is running GoTech instead of L-Jet, and I was hoping to further upgrade to GoTech Pro (coil packs, no distributor, hence the necessity for the crank angle gear and sensor).

Sam,
Fitting a aftermarket 60-2 ringwheel to the standard crank will have no effect on balance ( as JJ said), I miss understood your post, thinking you wanted to change the entire pulley for an Alfa 60-2 from 75 motronic 1991/2, or early 164.
The counterweights on the inside of the factory 60-2 pulleys WILL BE different, and require re-balancing with the crank and flywheel - the V6 crank uses these external counterweights on the pulley and flywheel to acheive proper balance.
As I said to Jes, you will be making a big headache for yourself just to go to coilpack's on a 12V.
1. trouble with the oil pump drive
2. machining a plug with a rubber seal for the hole left by the dizzy
3. clearance issues with the water pump pulley
4. finding front cover from 75 motronic/Alfa SZ - or tapping and threading the old front cover
5. aligning the crank sensor is critical +/- .25mm out and you will get missfires.
End result will be no gain in power, and will cost quite a bit in monies.
If you are going this way, please take some pics for us all to see whats involved.
Cheers

Andrew,
I fear you are right, but the good thing is that you can run pro with out the coil packs, so I can use the pro and try to get the coil packs working down the road.
We were going to take the advice of the earlier post and machine the 60-2 gear and press onto the pulley. But if someone has a pic of how the sensor mounts to the engine, I would like to see that.
The dizzy can stay where it is, just let it spin, not the best solution, but a simple one. I am not sure about the others, I have not gotten that far yet, first I just need to get the fuel working. Right now I am working on the standard GoTech on my Verde, so once I tackle that, I will move the bar up and try something new....
