As said, a capa supercharger kit at around $7k would be the easiest way to go for around 240-250kw.
At 190000km, your bottom end would probably require a rebuild to cope with any major mods. I have just done a complete rebuild and upgrade to around 250+kw and love the result, although it was not cheap.
IMO, first you want to look at exhaust, extractors, K&N air filter and larger EL XR8 snorkle and then some thermo fans to replace the stock belt driven fan.
Next, look at a bottom end rebuild if possible and get it properly balanced. Then look at some heads, the GT40P's are great value for money especially if you pick up some tickford 220kw modified heads. Edelbrock/GT40/cobra or explorer intake with a 65/70mm TB, roller rockers, good cam, MAF and larger injectors etc..... Just remember before you start, its going to be EXPENSIVE!!!
