If you are running the Autronic EMS with a MAP sensor, you don't have to worry about piping to the turbo compressor inlet, use a mesh over the inlet or a K&N style filter if there is space. To save some work, you could get the Border piping which will take care of the pipes going to the IC and from the IC to the TB. Then the only pipes you have to fab is the section from the turbo compressor outlet to the border piping. I would recommend you get a box full of cheap mandrel-bent 2.5" steel piping to figure out what you need, and buy the appropriate (expensive) aluminum pipe later...
