what is the easiest and cheapest way to squeese more power from my focus, i have a mk1 1999 zetec 1.8 standard at the moment.
do i go for exhaust, induction kit (polished pipes not plastic).
cams?

 

When i use to own my 1.8 , It was a little boring as standard..

The day i put a 4-2-1 piper manifold on it really opened her up !, I would stick a manifold, Catback on , Add an airfilter and see what you think then, Really did make a difference

 

haha sounds good, il give it a try but i really dont want a loud stupid boyracer sounding shed lol haha if that makes sense.

 

the biggest difference is removing the standard cat and manifold in favour of a 4-2-1 or 4-1 manifold, you will have to swap back though come mot time unless you have a friendly tester. coupled to something like a milltek exhaust you should see upto 15bhp more.

insuction side don't go for an open cone unless you relocate the battery to the air box and then possition the cone undernieth the batteries original location. then its cams and remap unless going for throttle bodies or forced induction.
