But it all depends on what kind of power you want to make I think 250whp is max for n/a engines but 350whp is what most turbos get but can go way past that.
where did you get your information from guy.
the focus will never be able to get 250hp N/A! with a basic bottom end turbo kit youd be lucky to get that. if i were you, id read up on the focus a little bit more, leave the information giving to the elders that actually know what there talking about, and get some more posts under your belt before giving out incorrect information.
