Is it best to use the medium sized one as with the Astra?? >> http://cgi.ebay.co.uk/ASTRA-G-GSI-VX...QQcmdZViewItem
Also what pipe work will I need?? I know there's loads of threads on them for the Astra GSi but can't seem to find any solid info for the Zaf..
Any help would be great as I don't have a clue how the best way to do it is??
