I know it's possible to fit aircon to a UK MY96 - I would like the full climate control thing from a WRX though...

Does anyone have any instructions or a list of the bits I'll need? I know I'll need the pump & compressor, a load of pipes and some controls... What else do I need - is it straight forward behind the dash? Then there's getting it gassed...

Also, how much does it weigh? I don't want to slow the car down too much, but I don't want to cook any more!

I need to get the cambelt done first, so I can wait a bit to collect all the bits.
