So I'm planning on swapping a b16 into my 2000 civic. It has a d16y7 in it. I know I'll need a different ecu, engine harness, axles, but what else would I need? Would also be wonderful if you could specify where to get it from also.

 

Check guides, stickies, google ek swaps....plethora of guides out there.

 

if you go to hybrid section, it has all the information you need.

quick crash list.

engine
transmission
flywheel/clutch/pressure plate
3 new axels ( driver, passenger and half shaft )
exhaust manifold / header
b series shift linkage
driver side 2 bolt post ( from 99/00 civic si) ( you can keep the engine mounts )
rear transmission mount from 99/00 civic si
ecu to match engine
probably a conversion harness
rewire distributor
rewire iacv
add vtec wiring ( if going vtec b series , if going b18b or b20 , not needed )
radiator hoses to work with the skinnie stock rad, or upgrade to alu rad

added things you might need aswell

coolant
oil
oil filter
transmission fluid
ball joints ( if you wreck them during swap, or if they are old )

 

Don't even have to go to the hybrid section. We have an FAQ sticky here that literally covers ALL of your questions.
