Be interesting to see how you go Waldo. I have a similar set up on my R32 GTS-t and i find it has the best of both worlds.
Like Roy's car mine is a daily driver as well and is very comfortable on the open road and is never harsh in traffic at all (all be it from the clutch )
and on the track i couldn't think of a better turbo that suits my needs (club/track days, motokarnha's and hill climbs and drift) as i dont change a single thing with set up except for tyres and some fuel.
The car is about to have a bit of a face lift due to some dodgy fuel that was acquired last week but hope to have it back on the road soon and will post up the new dyno sheets.
Look forward to seeing the numbers you get out of it and i dont htink you will be disappionted with the turbo at all, but like Roy has already mentioned i would do away with in the internal gate set up and go external. You will probably find in the long run with initional set up costs and if anything goes wrong or for modifications later on it will be a cheaper option???
