firstly sort the breathing, a Carbon closed induction kit with a direct air feed will do wonders on that side with the Rolla mani Then I would uprate the exhaust system starting off by getting a cat back system and eventually decatting it and a 4-2-1 manifold for a nice gain in torque Should be close to the three figure mark with these mods, then you can advance the timing a little bit to open it up a bit more Then fueling is the issue, Rich has just put bigger injectors in his n/a Starlet, pretty sure they made a nice gain, then you could get a Fuel pressure regulator or an Apexi SAFC II TO control the amount of fuel Hope this helps a little
