weekend project?! naw, we've pulled them in under 2 hours (no cutting!) and installed in 2 hours...making sure you have the right mounts is the main problem. Wiring is simple, if it's a SI anyways...just need to run 2 wires for the O2 sensors and 1 for the coolant switch...if its a DX or HF then you'll have to convert the entire harness to SI first then add the above. Of course that's using a hydraulic lift :-)
