Vx220 cam chain change norwich

Hi chaps just signed up to the forum and looking at getting my first z22se engined car which is likely to be a vx220. This will be a track car so I will be looking to change the chain as a precaution, few questions:

Anyone recommend a garage around Norfolk And what sort of cost I will be looking at?

Is it recommended to change the water and oil pump at the sametime on these engines?
Courtenays are the best garage in Norfolk for a vx220, but probably not the cheapest.

Water pump is a good idea, but the oil pump is roughly £400 new
