I would get her breathing before you do any many engine mods.
a set of pacemakers, lukeys etc etc extractors will do wonders, a cold air intake, different air filter too (you get a really nice induction noise from the pod air filters)
then MAF and TB...
I just did Yella Terra roller rockers (ST 2027), Crane Cam (Comp Cam 2031) and a few other things and got an extra 21kw at the wheels.. Its heaps more fun now :D
If you are planning on doing anything like that (or even stroking it) you should invest in a reprogrammable chip first... Without it the car will run s#*t house.
