b18 to b20 swap

[b18EGraaaaw]

i have a b18, and im upgrading to a b20z longblock, i was wondering if the b20 longblock bolts right in or i need anything special. im keeping everything like LS tranny, manifold, obd1 harness.. the b20 should replace the b18 with no other adjustments?

it will bolt right on.

I suggest you replace the head gasket and head studs when doing this.

Don't you need some kind of plumbing wires to finish everything up. Like the Tech43 lines to finish the pluming while doing the swap??
If not than...ok

thats for a b20/vtec

simply swapping the bottom ends or a head will not need it
