Anyone have finally made this modification ? I want to replace it to save weight, and I'm looking for a ref that I can mount.

Yes

Not difficult at all. Cheap 40 amp off ebay. A 5 rib pulley. A 5PK870 belt worked fine together with the original crank pulley. Compare old and new alternator on a flat surface to find out how many washers are needed to make the pulley align with the crank pulley. Add an additional wire.

Tssk, more like 100 Kg in my case!

 

I once had Nipper down to 895 Kg, now he is 970 Kg (with full fuel).

I wouldn't bother doing this mod if the original alternator on my car was OK, but since it started to behave funny and I wanted to replace it with a new one I thought why not go for this one instead

If you want a lightweight car, every little bit count, and this one is a huge saving !

My VXT is 775kg (dry weight) I hope to go to 750, it seems possible. (my car don't go on the road)

 

I have bought an mini alternator, I will post comment on it here later...

[harboged]

Of course you should do it! That's what you want and in your case it makes more sense since you have such a light car. I was just referring to my case with a 'heavy' car and my thoughts about it.

I don´t care super much about the total weght, I´m more interested in removing weight of the rear. I´m having a 59/41 weight distribution now

I want to come closer to 55/45.

 

So maybe I can make this fit my K24?  where to buy them from?

So the 50A zlet alt is a 3kg weight saving. Check

How does 50A behave on a roadcar? Any issues compared to the use of 120/100A ?

The seller I bought it from is not active anymore, but when searching on the model number shown on my alternator in the pictures you get some hits. Remember that you have to buy a 5V ribbed pulley as well.

There are also some Denso copies, such as the one below, which comes with the 5V pulley.

I haven't had any issues that I'm aware of.

I'm not an expert in electrics but as far as I understand it takes longer time to charge the battery and if you use too much power from your electrical consumers, then it won't keep up with charging the battery. I guess

Not sure but I guess the fuses give a good indication:
