Hi all I'm going to be swap shortly and I'm wondering if anyone could give me info on conversion kits.

So far I've found:

There is also the Alpina527 kit but it works out a little expensive for what is supposed to be a cheap mod. But the benefit of it is that its plug and play.

Cant seem to fit any ebay kits or similar?

I know its possible to diy it, is it recommended or is it better to buy a purpose build kit?
