I think you should just pick out a medium size torroid and just start winding and see what happens. If you have any sort of design goals I could give a more specific answer.

any good reccomended cores? i want to be able to put in about 1 - 3 Kw and
Look at TSC international and others, choose a core with an area you want for the following formula below. Choose the winding breadth and volume too, based on what you plan to do.

....how could i go about working out turns per volt?
Use the following websites and a calculator.
(Use this for conversion) (Use this for solving Volts per turn)

Im looking for somthing simler to Uzzors2k's Big Mofo HV Transformer EDIT: also should i run it ZVS or Full bridge?
Use a Push-Pull, Half Bridge, or Full Bridge, when your over 1-2kVA. In my oppinion Push-Pull is easiest but has limitations, Full Bridge is best, but expensive and the most difficult of the 3 to get working right. Half Bridge is in the middle.
It appears Uzzors is using a Half Bridge for his big MoFo transformer.
Build a driver that is reliable, then you can swap out transformers as you see fit or burn/explode them.

Then youll have to learn the math, Precalculus should be suffcient for this task. (if you want to know what is really happening, else you can just guess. Though at 2+kVA, guessing seems dangerous.)
