a unichip means nothing in terms of your fueling upgrades.

Along with that, you do not need a fuel pressure regulator.

Your choices in fuel pumps are the Walbro or Denso pumps. If getting the Walbro, make sure it's the 342 and not the 341 model. Although the 341 will work just fine, the 342 is a better drop in physically.

As for Denso pumps, either a RX7 or Toyota Supra TT replacement pump will work. The benefits to getting a denso over a walbro are mainly in quietness and reliabiltiy. You also pay almost double for these over a walbro. The RX7 flows at 210LPH and the supra pump flows at about 255 lph.
