Ok, I didnt want to hijack the turbo thread. (not that i think anyone would let me.) But I know i cant be the only sucker er i mean guy who doesn't understand how the fuel injection system works. Can someone post a link or explain, how an EFI or direct inject fuel system works, specifically what ever is on the rxp/rxt? I am at a complete loss on how a 50lb injector in conjuction with a 60lb fuel pressure regulator equals or is about the same as 55lb injecotrs with a 50lb regulator ( or something like that, fyi, Im basing my info off of what was said in the constructive turbo talk thread.) All guidance or info is much appreciated, about as much as this scotch and soda. thanks gusy
