with you wolf you will only need the bigger turbo. standard injectors are good for just over 400rwhp. my car has a rb25 with a wolf and 040 and its making 390rwhp, my friend has a r33 gts that was 420rwhp with a wolf and standard injectors. Only thing is with wire in it only has 4 ignition out put so you have to batch fire the coils, the plug in has 6 out out unless you have the wolf v4 plus.
