hey guys looking at upgrading my fuel system for e85 and getting a retune, just wondering will 550cc injectors cope with my hks2510 turbos?
550cc injectors on E85 are good for a safe 280kw at the rear wheels. Or 300 with a slightly higher fuel pressure. So I would say they are not ideal. Secondly, depending on the make of the injector, they may not be suitable to run E85 anyhow. S1 Nismo are no good if thats what you've got. Sards are ok, so are doucheworx, basically anything of pintle-less design is ok. You are also going to want to change your +ve to the injector loom to ensure it switches off with the ignition, stock has a +ve feed to the injectors while the engine is off.
