You would have to remove everything from your engine bay in your vr4, front subframe, remove dash, a/c, heater, fan, wiring, steering wheel pedals, clutch master cylinder, brake master cylinder, carpet,and windshield. Then drill out all spot welds on vr4 firewall and the same on jdm clip. Then weld jdm firewall into vr4 and install all jdm firewall stuff and subframe. Would also need jdm front door panels and jdm carpet (its different than usdm) and the body harness for he same year as the front clip. There are guys on here that have done the swap, jc for one, and can give you more tips on what you'd need. I think his screen name is jcgalnt-vr4 244. He's building a blue jdm swapped vr4. Good luck!
