genuine ford spark plugs only, gapped right for the set up
your turbo rebuilt too stage 2/3 spec as the stage one is no better than standard
decent actuator (this should be done on rebuild)
bailey or autospecialists breather kit, (second hand is cheaper)
full front mount intercooler kit (get this second hand in good condition) saves £100+
newman phase 4 cam with double valve springs and solid lifters (genuine ford is also good)?
chipped ecu (unlimited boost)

clutch?....... standard will need changing, i like the ap 4 paddle with uprated pedal mod....... best set up that works in my view

and a set up from one of the following companys
jamsport
norris motorsport
oddkidd creations
motorsport developments


on another note, i would look into a full service and remember too change the oil straight after changing the cam.

and if you went for a decent hybrid turbo you could get away with the standard cam kit if its a genuine ford in good condition and not a cheap pattern part, if it has a genuine ford one then i would leave the cam as its the most reliable for a cvh.

so on top of what you have get
stage 2 or 3 hybrid turbo
front mount intercooler
genuine ford plugs
breather system/ kit

limit for stock internals is around 240bhp on mfi, more on a mappable management due to having alot more control over ignition and fueling......
