Turbo is more cost effective than all motors on our cars. Sure you can squeze more power out of our cars all motor vs. stock but what car can you not do that? Zetecs are pretty well suited for FI, it'd be pretty stupid and a waste of money to try to go all motor on a zetec. Of course getting a good head, valves, and cams is gonna add power, all motor or FI.
The fact is, most zetec contour owners don't have lots of money. Hence why they own a car that can be had in good condition for $1k. They're not looking to spend $4k+ for a 70hp gain.
The best thing to do for a moderately quick zetec contour is what sleeperz did. He's ran the fastest verifiable zetec contour 1/4 mile times and probably put less money into his car than I did into my rice-mobile.
Now if you got the money for a modified head, cams, pistons, etc., go for it.
