Rover owners: [Help] '06 Mg ZS swap

Hi guys,

I guess I need some help with my MG ZS.

Got it brand new in 01/2006.. actually has around 40k miles, already replaced one head gasket and currently the BCU is collapsing. The 1st speed of the windscreen cleaners stopped working last year (but I could live without it).. the horn failed aswell a few months ago..and let's imagine what it will fail next..

So I decided to do something different.. after a lot of hard thinking and maths aswell (£££).. I decided to try swapping my 1.4litre engine..for the 2.0 T series.

I'm looking foward to buy a Rover 820 Ti (aka Vitesse) and swap them.

I will buy the whole car while it's fine to drive and then will sell it for spares..keeping everything that I will need.

My question is.. so far, after a long research here, I know that I will need:

-Rover 420 mounts;

-Rover 420 drive shafts

-The whole Vitesse loom, keyfob, ECU and "BCU" (I don't remember the name given to older models)

But.. why from the 420? If I'm going to buy the whole 820, shouldn't it be enough?

And if it's not, could any one please give me a little help to buy those spares? Here in Portugal we don't have the 420 model.. and luckly I found 3 Rover 820's for selling.. 2 of them.. at a very reasonable price.. but if it's not enough.. I can't buy all the rest.

If you know people that are selling those spares, please tell me.

Ebay links from the guys you know that have spares will help me a lot too!!!

If for some reason, the person will only do business in the uk, that's not a problem, I have family living in the UK and lots of friends all over.

Many thanks,

btw.. this is my ZS..
