This should give you up around 180rwkw with a healthy engine. Using decent quality roadworthy standard size tyres (225/50/16) you should be able to do consistent 13.5-14.0 sec with a 1.9-2.0sec 60ft at around 100-103mph, the rest just comes down to driver ability and how long your clutch will last.
Edit: You won't need an Apexi PowerFC, but it certainly would help and you certainly won't need a Z32 AFM (until you change turbo's atleast but by then you will also need a new fuel pump and injectors).
