there many reason.. People say S1 is good for stock Turbo.. mostly they have Cossi on Stock turbo and gave good Number hp and power.. so i heard S1 gave good power too.. but all my buddy have cossi and i drove them.. i like cossi. one of my buddy did S1 and swap to cossi.. seem cossi have more power and respond at Rpm low.

Well after reading that, I don't feel so afraid of Cosworths. If you're going to do cams, go big...but not too big I guess. S1s are perfect for the person who plans to always keep the stock turbo, but if you ever did a turbo upgrade, cam upgrade as well.
Cosworth just seems very well rounded. Lots of power without too much lost on the low-end.

Greg said my cams were fine
.... so i dont know. Maybe my car just didnt like them. As i have said before, these cams for a lot of people make good power, they just didnt for me.

thanks very much for the review! i currently have S1'a and i'm making decent power on the stock turbo so i don't feel the need to upgrade however the cosi's look like they would benefit me if i ever went to a larger turbo setup.
