Hey, i got a b18c swap in my 97 ex and the total cost was around $4100. Shipped with install with new water pump, timing belt, timing belt tensioner, wires, plugs, rotor and cap. To retain my ac I had to get a 94 del sol vtec ac bracket from my local honda dealership, and to have my power steering I had to go down to a hydrolic shop and have them modify the cable to work for my car.
For everything else that i needed to complete the install was a 99-00 si rear mount and a 99-00 si left side mount.
My headers matched up perfectly to my oem cat. I got my 1997 b18c from hmotorsonline.com for $3350 shipped. It was then a $550 install. $1,000-$1500 is a bit much for labor.
Good Luck with the swap :thumbup:
