as a straight up performance upgrade, the installation of a quaife ATB limited slip differential in your PG1 seems to be held in high regard by some. Apparently makes the most of the power the Z already has (I don't have one of these fitted, but am very familiar with wheelspin on damp / wet days - one of these ATB's should sort this out - perhaps someone with more knowledge can enlighten us all)
The down side of this is it'll eat up most of your £980 leaving little left for anything else.
