Ej1 B20B Swap Info??? Need Help Please
Hi. i am new to honda tech... but anyways i have a 95 civic with a stock d15b7 in it... but i want to go b series. My brother has a b20b in his da and it would be pretty quick in my civic. A big step up from a little d series. I know that it isn't vtec or anything but eventually i will probably put a gsr head on it or something. And this engine is pretty cheap on tiger jdm. only $490.00 and i need to know everything i need to get this engine into my car and running. I would really appreciate it if someone could make me a list of every single part i would need....here is the site i would buy it from:

Re: Ej1 B20B Swap Info??? Need Help Please
I will start you off.
*Note, You can probably use some parts off other year cars than what I list but I am just typing it the easy way*
-94-01 Integra Axles
-94-01 Integra Rear tranny Bracket(L Bracket)
-I assume you are going to want to run the B20B on OBD1 so get an LS(B18B1 Distributor, OBD1 LS Alternator(Or from what I hear you can swap the guts of the OBD2 Alternator into the OBD1 Alt. and do it that way although I have never done this)
-OBD1 LS P75 ECU
-94-01 Integra LS Shift Linkage
-94-01 Integra Intermediate Shaft
-94-01 Integra Throttle Cable
-And of course a B-Series Tranny. IMO shoot for a GSR,etc. The LS tranny has longer gears..I have a GSR mated to my LS and really like it.
-B-Series Engine mounts(I think you can use some from the D-Series, But get new mounts..then you know there new.
-94-01 Integra LS Radiator Hoses
-99-00 EM1(Civic Si)Radiator(or use hose clamps and tighten the bigger B series Hoses on the D-Series radiator..I did it this way and have had no problems at all..But use your best judgement here)
-94-01 Integra LS/GSR Clutch and Flywheel.
-You should be able to use your D-Seires OBD1 Engine Harness. Should be plug and play but you might have to extend some wires. I know the B20B is OBD2 so it utilizes 2 02 sensors..so I don't know if any other conversions are neccessary or if you just plug one of the 02 Sensor ports and only use 1..hopefully some others will chime in.
I swapped in my LS but everything was already OBD1.
Hoped this help get you started.
