I run an 02 3door focus 1.6 se, it has highly modified suspension and brakes but i want the block, head and box to remain standard. i'm looking for ideas on bolt on mods, such as filters, ecu, plugs etc to add. any ideas? I'm looking to track it, but want to drive it there and back.

 

The Zetec SE isn't to bad but it's not cheap to tune for the return, 135-140HP is achievable with aftermarket cams a remap and a decent exhaust manifold. Then things get more expensive when you start going down the throttle body route.
