Thanks for the advice so far.
I've just gotten a quote for Pacemaker extractors, cat and system for $820, and i've been told the stock cat is fine to leave on (with only a 4kw gain by replacing it). Which shaves $250 off for a total of $570. (Mate of a mate is the manager)
I'll check my accelerator cable for any stretching as well, just in case
I actually have a Simota racing pod at home, which i had on in place of the stock air filter (piece of 3" exhaust pipe joining it to the stock intake hose) a while ago, but put the stock one back on for the warranty service
I'm yet to put it back in place, but probably won't yet as it didn't have a heatshield and probably wasn't helping. This time around, though I'll probably get a custom heatshield made up and rig up some kind of cold air induction (and have to check out this air intake behind the headlights). After I check my warranty to make sure I don't void it.
I'll probably, after that, fix up some minor defects present in the body styling; cracked the front spoiler where it joins in front of the LH wheel arch when entering a steep driveway :/ (hopefull i can get that fixed, otherwise anyone know where a replacement or alternative can be found?) and the rear "wing/spoiler" has become "unstuck" in the centre probably from lifting the boot with it or people leaning on it.
Other than that I'd like a set of 17s (not chrome, too much of that in this town) and then altered suspension.
Might look into replacing the cam too.
I can see my budget being blown away
