B-Series Engine Swap Basic Info

Basic run down and price estimates of what you need to acquire:
B-Series Swap Engine Brackets ~$800
Engine Wiring Harness ~$550
Basic Axles ~$225
Shifter rods and shifter ~$150
Shifter rods lengthening service ~$190
Non-VTEC (B18b) Complete Change Over ~$2200 or VTEC (B18c) Complete Change Over ~$3200
Incidentals ~$500

Non-VTEC Total Cost ~$4500 or VTEC Total Cost~$5600

Of course those are just typical prices, you can save quite a bit by deal hunting. Probably the cheapest way to go is a JDM B20b ($600 shipped) mated to a USDM 94-91 Integra transmissoin. You will have an engine with equivalent power to the B20a/B21a but far better aftermarket and upgrade options, like a VTEC head swap.
You can have working accessories as well, power steering, air conditioning, cruise control. However those will add extra cost as the P/S and A/C require custom lines and modified chassis wiring to work.



Here is a detailed write-up for this swap:
Sorry, currently there isn't a detailed write-up but it is in the works.


Here is a video showing a B20b swap in action:

Pros & Cons:
Pro:
Non-VTEC B-series engines are very cheap to acquire
Massive aftermarket support
Doesn't require traction bar
Compatible with stock rubber mounts (Low vibration option)

Con:
Reduced ground clearance (But far better than H-series swaps)
VTEC swaps and parts seem to be more expensive than H-series counterparts

Swapping an F-series from an Accord is the same procedure as an H-series swap. See this thread for more info on it: viewtopic.php?f=9&t=28
You can't rationalize cars like these. They're not something you buy with your head. You buy them with your heart because you love them, and who can explain love?
