Does anyone know if the stock fuel pump will be sufficient for the ID1050 injectors?

I think the stock fuel pump will work if you use 91+ octane gas. The only problem is you will need a custom tune in your car for those injectors. Hondata only has tunes available for up to 800cc injectors. I would ask your tuner what your fuel needs will be for your build. Do you have anything else done to your RDX?

I have the ets intercooler upgrade, rv6 downpipe with high flow cat and a flashpro. Looking to do the injectors upgrade and add a intake. How much HP roughly do you think I’d be able to squeeze with this setup? I would consider the turbo upgrade as well but this is my daily driver and can’t afford to have it road for too long.

Without the turbo upgrade your looking at 254+ to the wheels. For the turbo upgrade you could order a spare turbo and have that one redone. Then when it’s ready you just swap them out. That’s what I’m looking to do soon.
