Im trying to find information on the duratec engines, ive only just learned that some of them have VVT but cant find out if the 2.0 ones do, i know that only some of the 2.3 ones do but im wondering if anyone knows a site (ive tried wikipedia but its quite confusing) where i can get information on the specs, modding it and conversions etc. also anyone know where i can buy one?

Thanks in advance, Dave
