Geordie56 - turbo comes with manifold but a normal k04 does not fit, it needs a bit of modification, you'll also need all the dv relocation stuff.
Your car has already got good enough injectors and the hpfp is up to the job too
If you were going down standard k04 route internals are up to it but wouldn't fancy going down hybrid k04 route on standard internals.
My mates k04 mk6 gti pulls away from my 360bhp mk5
