ye're better sticking to the f17 in the zaf, you're gonna have issues with the c20xe as well because the engine in the zaf is mounted at the bottom to a x-member, and the red top is mounted at the top, so you're gonna have to weld in a new engine mounting. rather you than me mate, but i'll say this you've got balls for attempting it, so respect from me lad, Lol!!
