ok so i just bought the walbro 255lph from summit and then I was reading on another website that its not reccomended for nitrous. It said the high pressure pump is recommended for nitrous and superchargers and turbos. Does anyone think this really matters? If I decide to throw a shot of nitrous on the car later will this really make any difference?

i bought the high pressure one from JD and installed it on a stock 86 5.0L not a single problem installing on a stock or N/A car but my plans include boost

I probably should have went with the high pressure pump but Im sure there are tons of people out running nitrous, just fine, with a regular 255lph. I wonder if it really makes much difference.

you can run the 255 without issue, even on a stock 5.0
