Yup, it was used on rabbits ( like I said, VW, Porshce, Audo, Mercedes, Volvo, Saab, BMW.)parts are available, cheap, and easy to deal with.
what I'm planning on building is a manifold system like the mercedes used, with the injectors, warm up regulator, throttle plates, fast idle air bypass, and air flap meter all attached to the manifold - makes for a neat, tidy install. all wiring predone, just mount the fuel pump in-line as per instructions, add a 12V switched source, and voila, instant multi point FI. I DONT plan on using the stock intake, as I specifically want to mount everythig to the manifold - thaty way the wiring can all be pre-done, and there wont be any issue swith 'where to mount' assorted components. I'll also be playing with the injector sizes for best efficiency on, and modifying the intake to a 2 1/2" round port, suitable for an oiled cotton filter, snorkle, or both.(still working out all the details in my head here)
$300-$500 is what I figured as a reasonable cost for rounding up the parts, building a custom manifold, and doing all the wiring to turn it into a bolt-on kit. I dont think I could do it and make any profit for less than that.
