Hello all. Im in the midst of putting an S-trim on my 92 GT. It has a DSS 308 w/ ported Edelbrock Perfomers (2.02 / 1.60) , extrude honed Cobra intake, Wolverine 1087 cam w/ 1.7 rockers, BBK longtubes, 75mm TB, Pro-m 80mm, UPR Powerpipe, and a 255 in-tank pump. I had planned on installing the T-rex, but I read somewhere that it was not a good idea to put a T-rex in front of a 255 pump. I am going to be running 42lb injectors and hopefully no FMU. Is the 255 enough by itself? What about the high pressure 255? I'm hoping to make around 450 rwhp after a good tune, and I need a fuel system that is up to the task.
