very nice build. i'm using the same turbo, but on a built 7m. i went with 1000cc injectors, and they mite still be too small. i'm hoping for 6-700hp with this turbo. i'm told it flows enough for 850, but we'll see.
also, as far as pumps go, i have an aem 320. i know it's going to be too small, so i might do 2 in tank or a big external pump. i have some 1600 cc injectors waiting in the wings if i decide to go e85.
