Question Forester Upgrades

Hey,

I just got a 2001 Forester but because i live in Australia....well we didnt get the 2.5l till 2003 so i have a 2.0l problem is i miss out on about 20kW and a fair bit of torque! i know thats not to much to gain but what does everyone think? how should i increase power and torque without engine swapping or induction? I'm thinking headers, exhaust blah blah but am unsure, anything else?

Any help would be great

Thanks guys

Apex-i Super Air fuel controller. Gets wired inline between your MAF/MAP and alters the signal causing the ECU to change the duty cycle of your injectors. This allows you to lean or enrich the mixture appropriately to produce maximum power. Its more effective on the MAF based cars, as the MAP cars tend to learn around the s-AFC.
