What model is your dsm, Fwd, Awd, Auto, Manual? I have a non e-prom fwd 5-speed for a 90. Eprom is only worthly if you plan on going dsmlink or use another type of chip.
What elbow are you looking for 2nd gen?
With a larger turbo you will definitly need larger injectors plus something to tune with ex. safc or link.
What size intercooler are you looking for? With piping or without?
I maybe be able to help you out but will need more info, feel free to pm me.
