^ I'm not to sure if his motor can handle the power that turbo is capable of but I know for a fact that 750's are to small to take advantage of the 500. I ran DW 750's with my AVO 380 and they where pretty close to maxed on pump and I couldn't even run E85, well atleast It wouldn't have got me much if any of a power gain over pump with thoes injectors, so I went to the DW 850's so I could run E. So in my opinion I would go with the 1000's because now that I no longer have the 380 and am running the 20G my 850's are maxed out on E and I am kicking my self in the ass for not skipping the 850's and going straight to the 1000's because now I'm looking at having to shell out more cash on a third set of injectors. Your 500 is still bigger then my 20 g witch is just slightly bigger then the 380, so don't make my mistake give yourself some breathing room. A good tuner can make thoes 1000's idel just fine I've seen some very smooth running cars that are using 1000's so it can be done.
I don't have to be mad to punch someone in the face!
