Great choice of car mate, these cars never disapoint their owners. As for mods, I'm not too sure who you could go with to get it done over there. sorry the 4 speed auto is good for around 280-300rwkw By average, some can take more, some take less. And these cars are limited when standard, but a custom tune soon takes that away for you.. If you're looking for a 300ish figure which is most blokes on here do. youd be looking at: Injectors,Valve Springs (MAYBE), Bigger Cat/Dump pipe, Stronger auto (Another maybe). Then you could either get an exhaust system or an Intercooler Kit. Put you around the healthy 300's
