well,If i am using the entire cl motor,cl engine and cabin harness and ecu,obd I won't matter,the car will now be obd II. The biggest problem is by the time I get the motor up off the ground,I'll need a cowl hood and have to definately make custom wishbone's to let the higher set axels through,which means shorter struts. I'm looking at the idea of... buying an entire front clip from a salvaged car and welding the frame rails forward to my eg chassis. that would make to engine and chassis bolt right in but, since its wider,the front wheels will stick out further in the front than the back and that would look like hammered shit. The more I look into this it aint worth it. I also own a 2000 accord coupe and keep forgeting how much smaller my civic is. I still would like to do something different maybe look into a k-series swap.
