12-15k would be doing it cheap too...

Engine + trans = 6-8k
Mounts/axles/harness = 1700
clutch line/fuel setup = 700
all new fluids/some gaskets etc = 200
intake/headers/exhaust = 1500
ECU/Hondata = 1500
misc bits and pieces i cant think of = 200
rad/hoses/fan = 300 - 1k
If your EG isnt EFi = 600
brakes/suspension upgraded = 1-3k
engineers cert/registration/RWC etc = 2k

Adds up real quick. They are some quick estimates for you.. I'm sure theres things i missed.

You could save money buying used parts etc.. But overall, the swap ends up expensive in the end. You will no doubt find things that need replacing along the way aswell.. I just spend close to $100 on 2 new OEM ball joints that needed replacing... All these things add up...
