well the rs2k should already have a 36-1 tooth pattern and crank sensor so you won't need that! You'll need a map sensor that can read positive pressure so something like a 3 bar. Then you'll need a coolant temp sensor and an air charge temp sensor. Also a throttle position sensor. Your car already has an air and a coolant sensor as well as a throttle sensor so you'll just need a map sensor. I believe the latest ecu's can run coils directly so no need for edis modules. Thats a start for you.
