I have a 2002 Ford Focus ZX5 with a 2.0L DOHC Zetec engine. It’s currently stock, putting out 130 hp and 135 ft lbs of torque, but I’m looking to change that. I’ve never modified an engine before though, so I need to ask, “How do I get it up around 160 hp and 160 ft lbs of torque without adding nitrous, a turbocharger, a supercharger and without totally emptying my wallet?” Any suggestions would be much appreciated.

A few things you could try are a bigger exaust system like a 2in or 2.5 in some extractors, and a underdrive pulley kit would be the way to go just bear in mind though the fuel injectors are limited to around 175 hp so if you want more think about upgrading them as well also get rid of the air box and grab a cold air intake and a half decent air filter that should get you started. let us know how you go

Zetec

Yep - extractors/headers, 2 1/4 inch exhaust with highflow muffler, cold air intake and run some decent fuel, you'll be laughing. You'd also need an engine chip to lift it to about 160HP.
