What will the k20a or k20z3 engine fit into? Without a lot of problems that is. Would it fit into a 2003 civic? or 92+ civic for that matter? What do you recommend for these years if this engine wont work or is to much trouble? Really would appreciate the input. Just so many options out there! Thank you!

 

K motors will bolt into anything from an EF up, with varying degrees of difficulty. Its a fairly common swap into an EG, but is still much more expensive than a B series swap.
