BMW MINI alterator

[crankedup5]

The alternator on our BMW mini cooper 2009 model is giving up and needs to be replaced soon.
I have looked at Europarts for the replacement and they offer two differing amp outputs.
150amp at a cost of £450
120amp at cost of £260.

Both alternators are RTX brand. My question is can I get by on the 120amp output?
Our car is standard as factory with A/C.
Thanks.

I would fit whatever size you have currently. I think those may be exchange units anyway.
(P.s. don’t forget the ECP discount code as prices are actually lower than you quote).

Thanks scrump, and I had overlooked the discount code.

I’d fit anything but rtx as they generally don’t last long. I’ve seen rtx rotating electrical part not last a day a few times
Just a heads up.
And the mini can be a bit of a pain to do due to lack of access I’d only want to be doing it once.

^^^^^^^^
Thanks, last thing I would want to do is a alternator swop more then once on a mini!!

I bought a used (genuine) one for £25 delivered. It was 120amp one as that's what it has. Standard Mini Cooper with Stop Start.
