I currently have a box 475/83 1.0 t-4 that i ran a little on the truck with less fueling. It was a laggy turd. I also ran a precision 2.6 gt4294 on the truck years ago with big fuel and enjoyed it on the street. I'm looking to just use it as a cruiser, and the brush pull 2-3 times a year hince the 75mm limit. I have been looking at a fleece s475/87, or s471/87. Would it be work keeping the 475/83/1.0 and adding a wheel to it, or is the 87 turbine that much better. Also can get my hands on a garrett based precision 3x3.35 1.12 t-4 that was ran on a very competitive 3.0 common rail truck, I know the power it will support, but unsure how laggy it will be, or if it's over kill. If anyone has experience, or numbers that would be appreciated. I'm also not stuck on those choices, so throw out any and all suggestions

45 lpm injectors - are those DDP or?

I would look into a gt42 or a 472 and get a hold of smokem
