turbo sizes

im going turbo and well i am not to familiar with what i should be looking for. my benchmark is 325-350 on a s5 t2 engine. i am going to build this engine for track only so other mods will be done. i was just wondering what some of you guys think i should run for a turbo size. and what sort of things i should look for when buying a turbo. t3/t4 is just compressor size or is that the main size of what im looking for. i am really lost here so would like some advice thanks in advance.

there is a ton of info on this type of stuff in the single turbo section.

Im not sure about the s5 turbo setups but I would look into a BNR turbo if you are only looking for 325-350 whp. They allow you to use a stock length downpipe, and a stock exhaust manifold plus it has an internal wastegate so you dont really need to worry about that either.

Obviously you will need other supporting mods, mostly in the fuel department.
