[Insane horse power?]

Hi all,

I’ve got a series 2 td5 2.5 diesel with a few bits done to it already but I’m after more. It will do 100mph+ and is fantastic at sliding all fours wheels around off road. It’s got a 6”lift kit, massive wheels. sequential box (fitting it Monday), competition props, it’s stage two mapped, snorkel +K&N, uprated injectors, uprated fuel pump, decat, EGR delete etc. Really I’m looking for bigger turbo ideas and what kind of crazy HP I can push this thing too. Has anyone tried nitrous or water/meth injection?

Any advice is much welcomed.
