I am getting a walbro 255. That should be plenty to feed a 6.0 with cam, and 200 shot of nitrous. I don't plan to run more then 100-150 of nitrous till the end of next race season. So if I need to go with a standalone setup to make 200, then, I will or just won't go that high. I am pretty sure I will be fine just want to make sure.

 

It should be fine. I'd hook it to a wideband when you first try it just to be safe.
