Go for an induction kit first up.
Id say GruppeM or Tegiwa replica.
Then get a 2.5" b pipe and a new manifold! Dont worry about the backbox as this is good for up to 300BHP.
Next Kpro and a remap and also FRSU.
This totaly depends on your budget really and how far you want to go, The first two things i would advise is get a decent set of tyres fitted, then go for brakes, a set of drilled and grooved discs with some decent pads, braided brake lines and a tegiwa brake stopper can all be found online for good prices, these are both an excellent starting point.
hope this helps mate
