today a friend of mine asked me which engine would be better in his 98 ex the d16y8 or the b18 non vtec from his ls. I told him that I thought the ls would be better. He made me an offer to do the swap for him what all do I need from the ls to do this swap? engine tranny I know what else though?

 

this has probably been covered about 500x but I'm bored at work.

To make everything 100% bolt in and go easy, you will need:

motor
trans
shift linkage
mounts
axles
wiring harness
throttle cable
fuel filter to ful rail hose
ecu
any lines attaches to evap canister
radiator hoses

When you do the swap, the exhaust manifold on the ls motor will not bolt onto the civic exhaust, so you will need to have the exhaust modified.
