I got into an argument with a guy today at work on a 91 stock TPI fuel rail had suffecient inner diameter (volume) to flow (8) 60lb fuel injectors. I'm going to run the Seimens Deka 60# injectors that Lingenfelter sells. He was babbling about turbulent flow or something. I want to know if you run 42# or greater injectors if you have the stock rail, bored it out, or went completely custom.
