wow i dont know what the helll problems you guys had, its very easy to get a s14 ka into a s13, i did it with no problems at all here are some tips
keep the s13 lower intake mani and bolt it up to the s14 upper, this will delete the secondary butterflys
keep the s13 distributer and install it into the s14 motor
if you are keeping the egr and shit, the plate on the back of the head that holds some vac lines will only be able to be bolted it up to 1 hole i belive.
obviously you will from now on need to get a valve cover gasket for a s14 motor, since the head mounts it in different places.
and thats it its really not that hard its pretty strait forward
