You have an real experience with EFI? What exactly will reduce reliability?
I can be done for under $1000. And done well.
Instead of using the kit this
may be cheaper and easier to use. It will even autotune E85 with a sensor. If you look around the 'net there is tons of good info on homebuilt EFI.
