I wanted to do a k-swap to my 2000 civic si, so i wondered how much would it cost me?
most of the prices are from hybrid-racing.com
This is what i found.

mounts= 399
axels = 270
throttle cable = 20
clutch line = 95
clutch = 300
flywheel = 300
ecu = 100
kpro =1000
engine harness= 100
conversion harness = 350
fuel rail = 160
fpr = 180
fuel pump walbro 255 = 119.00
fuel lines = 50
oem injectors 410cc = 200
rsx shifter = 100
clutch line kits= 100
shifter cables = 350
radiator relocation kit = 20
radiator = 120
hose = 20
coolant temp sensor = 32
radiator fan switch =47
intake = 50
intake manifold = 240
intake manifold gasket = 50
throttle body adapter for rbc manifold = 50
throttle body gasket = 15
header = 400
exhaust = 400
total price? $5448 this is before taxes and shipping. 5829.36 after tax. without shipping. You could buy a RSX type-s if you add a little more. This would also be a swap that is done right, and i'm sure i'm missing some misc things. You could probably save a little money on the swap and cut some corners.
this is not including the long block of your choice. just the amount of money to get this stupid motor into your car and running. i think i'll stick with my b-series.
