I was thinking about buying a 1992-1995 Honda Civic Si (hatch) shell and buying a k20z3 and putting it in. The motor is like $2000-$3000(includes mount and everything to do swap) and the shell should be no more then $1000. How much is the swap if I take it to a shop? Is it hard to do the swap? Also is there anyway for me to keep the power steering and ac. I want ps and ac because it makes life more easy.
