looking for performance parts b200ft

Hi there,

So i found it rather difficult to find some performance parts for my b200ft.
Finally i found some strong connecting rods, but pistons and bearings i can't find.
I wan't to be able to run a high amount of horsepower (350-450) and i need some strong parts.
Does someone know where to get these?

thanks in advance

Why not start with a B230F instead?

Who says you need stronger pistons? Most people use the stock pistons and only upgrade the conrods.
