There is no such thing as a B20B/Z full swap. It only came in the CRV and that tranny won't work and I believe the CRV intake is too high and won't clear a Civic's hood. The price you are getting for the B20 is probably just for the long block compared to the LS's full swap price which would include most everything for your Civic swap.

 

does the "swap" come with the wiring harness, all the accessories (power steering pump, alternator, etc) or at least the mounting brackets, exaust manifold, CV axels, ecu. If not, to peice that together will cost you lot of money.

 

b20Z is from 2000 on right?

Anyways these guys have a 2k b20 longblock for $880

So you are saying someone has allready pieced this swap together and installed into another civic and you are buying his complete swap that includes a B20 motor with OBD1 LS intake, distr, harness, ECU, a GSR tranny with axels, shift linkage and all mounts? If you can get all that for 2K I would say go for it. It won't be the quickest car but you could probably tow a big boat with all the torque. Later add a VTEC head and new pistons and some tuning and it should be reasonably fast. The B20/VTEC is what I want to build.

 

Isn't the P28 a SOHC VTEC ECU? The B20 is not VTEC (unless heads were swaped), even chipped that ECU may not be compatible.
