You dont necessarily need aftermarket injectors. I was using stock injectors all the way through. And he stated that he already has the Walbro. Thats enough for stock IX turbo. But if he did go with injectors, he could use 1000cc with the right scaling.
Edit: I know I said that I made 380hp with stock injectors and NO alky, but I also had cams, full 3in exhaust, test pipe, o2 housing, intake, and was also using ECU controlled boost.
