Mods - Well, hard to beat the classic Intake/Header/Exhaust combination for starters. Before I'd do much more than that, I'd focus on suspension. At 80,000 km the suspension is likely OEM, original.
Doesn't matter how much power your engine has if you cannot effectively get it to the road - that's my Rule #1 - Suspension to use what you already have before you try to add a lot more.
