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.
Bigger valves are an obvious addon 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.
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.
