Dont worry about upgrading your ignition its really pointless the stock external coil works just fine. It really depends on what your goals are with the car as always. If you want to tune it I would definitely get it converted to OBDI. Im sure if you did a search you could find all the info you need on doing that. Look into getting the BPI Flowstack
BPi - Performance Velocity Stack to go with your V2 intake. If it isnt a daily driver you could get rid of the A/C, power steering, cruise control, and ABS system to clean up the engine bay.
