Martin, On the GTR's there not ITB's as such just butterfly valves used to equal out the manifold pressure (or something like that trying to remember what my dad told me on the phone now)

Well having looked into this more and after speaking to a well known tuner i can say that ITB's with a decent set of cams should net gains of around +30bhp and +30ft/lbs of torque but at a cost of around £2000 to £2500,

like martin said you get more bang for ya buck with a TT engine, so i dont think i will be going down this route,
