i have a 94 ex and was wondering what was necessary to drop a b20b? they bolt up to any b-series tranny right? are they obd-1? all harnesses plug and play? My car is stock if that means anything to ya.

searched and still can't find what i need to kno. my car is obd-1 and i believe that the b20b comes out of a 96-98 crv which should be obd2 right? how will i get it to work in my 94 civic ex?

man...

you gonna need to get OBD1 harness but i believe yours will work fine...you gonna need OBD1 Injectors, dizzy, ECU...i think you gonna need to run a OBD1 P72 LS ECU but not 100% sure on it...maybe someone can confirm/correct me on that..if you get the OBD2 harness , ECU, Dizzy, injectors...you can use them but you gonna have to use a OBD1-OBD2a ECU Jumper harness if the motor is 96-98...if its 99-01,you gonna need OBD1-OBD2b Jumper..

oh yea...you cant use CRV axles on your car...you gonna need to get other axles..

b-series motor mounts and bracket, b- series shift linkage, b-series axles, LS obd1 ecu, dizzy, alternator... u can still use ur stock civic ex harness.. u might wanna switch out intake manifold to the LS one too.. dats about it

so.... the 96-98 b20b is obd1? i knew about the axles and what not. umm... so my harness will work? and the stock injectors and fuel rail should be fine then. my main concern is the obd. if it's all obd-1 then i should be good to go

your b20 is NOT obd1

you CAN use your harness, it'll be ok, but you will need to get other parts....read above, all the info should be here allready...

any more questions??

o ok, i got ya now. i didn't read right. sorry. so the engine is obd-2 and i'll need to swap the dizzy,ecu, injectors and stuff back to obd-1. which would mean just use some other b-series obd-1 components. thx a lot man. any links to completed swaps with pics? all the one's i've found have dead links for the pics.
