Hey Scotty! Big fan.

I have 2000 honda accord lx 4 cylinder, my mom had a 2000 Honda accord lx V6 engine but recently got into a front end collision. My question is before i scrap the car, what parts should i take and save for my car or sell on the side for a better profit? Also if i swap engines and put a V6 into my 4 cylinder car, would i have to swap out the transmission as well?

you would have to do tons of stuff to swap that, I would never try it. Unless you are opening up a junk yard, best to just say goodbye to that 26 year old wreck
