What is the diffrences in these two engines? I want a zc engine bad for my crx but there is a d16a1 with lower comp pistons and some head work for 600 bucks for sale localy. Whats the diffrence in swaping them. I know a zc bolts in but does a d16a1? Its from a 88-89 teg. I have the stuff to turbo it to. I just dont want to have to remake engine mounts and get a new tranny. Thanks. Oh and there are some tunertoy rods for cheap to 175 are these good for 15 lbs of boost of so?
