I have a 99 Civic EX automatic and I'm looking to swap the 200hp prelude engine in there! I cant wait. But i need some info first. Maybe you guys could help me out? I found a engine on ebay for $1200 with tranny,ecu and everything. What do I need for everything to do this swap?? Im going to get it done at a shop. How much total, no bullshit do you think it will cost to do this swap estimating? Do you guys know anyone who has done this? If so what have they said about the handling and everything? Thanks. Oh, and will i have to get rid of the Greddy Evo exhuast system i have on my civic now or will I be able to keep it?
