My SP6265 is getting 1000 cc injectors (ID, Injector Dynamics), but I am also using a standalone (HKS Fcon Vpro 3.3). The ID injectors are a bit more expensive, but they have the ability to cycle down so you don't have to worry about overfeeding. I have the Denso MKIV fuel pump in my tank, so I will see if it feeds enough. (no wire modifications)
Mind you.. im running 7M, but still don't expect anything to fit as you think it will. I keep forgetting that installing a modification is just that... a modification. It means adjustments to accommodate.
