    I think that is a XER engine in that model? Start with making it breath better by fitting a sport's air filter like the K&N panel filter! The restrictive exhaust manifold can be replaced with a sport's 200cell cat manifold or even better a 4/2/1 with no cat then into middle box then straight through to the rear and no box. Might be a bit loud though but it will release power that was being restricted! A remapping of ECU would be needed doing this. My friend has a Corsa with this engine and he has done the 4/2/1 modification and fast road cams and had it remapped on a dyno. Power is now up to 180bhp and does sound good.
