i want some power for this summer but am probably going turbo next summer....what parts (performance wise) can i put on now then use on my turbo engine?

the list starts
short shifter?
pulleys?
electric fan?
s-afc?

 

all of those you have will work. A cat-back is universal. also a midpipe to replace that cat is universal as long as it only replaces the main cat. the airbox/AFM is mounted in the same place, so you could make an intake. you could buy a CDI module for better ignition like MSD 6A or Crane Cams HI-6 with better spark plug wires to compliment that.
