im posting this up for a friend who has a 1.6 zetec focus (2004). I know this engine is not very tunable, but we are trying to consider which way to go about getting more power. At the minute he has a scoprion cat back exhaust and a viper induction kit. He is considering the van aaken turbo kit, which i assume will fit? has anyone had any experience with these, or would it be better to go down the NA tuning route, cams, headwork etc?

I personally think he should drop a bigger engine in, but due to insurance, this is not possible.

Any advice would be most helpfull

cheeRS!
