I wonder if a k20z3 and all components fit into a 1993 civic, including exhaust and suspension system?
motor and tranny yes, with some modding and some good convertion mounts. Suspension out of a car that has the k20z3 no exhuast no way, exhuast are mandrel bent to fit in the specific cars underframe. Unless honda made a special civic back in 93 with a stock k series motor i highly doubt you will be able to bolt on the exhaust. Just get a new exhuast your already going to spend around 7k to get this set up in your car speend the extra 3-4 hundred and get a decent exhuast.
