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.
After 150whp you need tall money or machining skills to go higher with a N/A Zetec. Boosting will cost close to the same but, the gains are much better.
