Hi, I've just bought a 2.0L S111 auto 58 plate and I love it! am completely new to mods and wasn't going to bother but after reading about them I'm hooked and if possible would like some advice on improving the performance. I have £2000 to spend on parts for now and have read about air induction, sports exhausts, 4-2-1 headers and re-mapping etc but would just like some thoughts on the best ones to start with from people that have done it. I will eventually have a supercharger fitted but at the moment am just enjoying my car. Any help would be greatly appreciated.

The best mods for a car engine are as follows.
Internal work yields the biggest gains, head work like porting polishing and 3 angle valve jobs will maximise the airflow and raise the power.
If you want to go to the max then cryo treat the block, get it rebored and look into blueprinting and balancing as well. You'll also need stronger internal parts if you are looking at a big power hike so forged rods etc.. are the order of the day.
Bigger valves are an obvious add on but not all engines are suitable as it depends how close together the OEM valves are.
A fast road cam will yield good power gains, especially in the top end of the rev range. Don't go mad though a profile of up to 270 degrees will give the best gains without the engine becoming cammy (lumpy tickover at low RPM).
The most popular power mods are induction kits (which are questionable as power mods but they can sound nice if that is your sort of thing) and sports exhausts with sports catalysts or decats.
To keep the car legal I'd recommend a sports catalyst rather than a decat.
The last mod should always be a remap as this will allow you to fully realise the power gains on offer from your mods. Turbo cars respond very well to remaps.
It's worth having a read of the articles on www.torquecars.com/tuning/ for more information on these mods and what the terms mean.
