   need some even bigger injectors for the VTR as the GTi6 ones will not be enough , looking at VXR injectors at the moment they look to have the right injector plug shape but unsure if they are the right length ie longer picco style and not short picco style

   mmm gti6 injectors supposedly 283cc @3bar so 3.5bar should see them over 300cc quite happily

   Might be worth a shot. What's the current duty at max rpm?
