I just picked up a (as the subject says) cheap but it is from a R32 eccs engine and i have the old nics engine in my r31, what i want to know is will an eccs cyl head work ok on a nics engine and what mods would need to be done to get it to work, if there is no way to get it to work i will just fix up the couple of things that need fixing on it and sell it.
