bryan, on the stock turbo you dont need bigger injectors... if you have a flashed or chipped ecu, you may consider a walbro 255lph fuel pump. but until you go with a bigger turbo you will not need injectors... 300cc is plenty for up to 17psi on the stock vj14 or a vj14/11 hybrid turbo..
Fred (icurunnin) is running the injectors to basically get that out of the way, for when he gets his big turbo...
a walbro 255lph low pressure will be your next logical step after you get a rocketchip, and a vj11 hybrid turbo, for making more power...
there about 100.00 shipped off ebay, or most aftermarket online stores...
then, if you want more, talk to fred about his 390cc injectors and talk to rocket or someone else on here about the t-bird hybrid turbo
or do like me and fred and cory (coco customs) and think about moving into mitsubishi turbo land... be good ...Joe ...RCI...
