Default Questions about stock fuel pump..
Im going to be running a rhb5 trubo from a probe with the afc hack, and im wondering if i really need to install the walbro. is a 4th gen civic Si (EF chassis) good enough to handle the stock 8lbs of boost that turbo puts out (and the fuel it needs)?

Your stock fuel pump will support 280 whp at stock fuel pressure. I'd say you'll be okay.
