so my buddy was saying that i can wire a b20b with a d15 i call BS just wondering what you guys have to say about this issue

THC07

hes right, you can.

get both books and youll see how easy it is

Yeah, and since it doesn't need VTEC there's no extra wiring (at least not that I can think of off the top of my head) unless you have an OBD-II B20 going into a chassis that originally had an OBD-I motor in it in which case you'll either have to get an ECU w/ an OBD-I B20 basemap loaded on, get a chipped ECU w/ a OBD-II B20 basemap loaded on but with the extra sensory (2ndary O2 sensor, iono if it has a knock, but that too, etc.), or wire up all the extra sensors (not worth it) - or, obviously, use an OBD-I B20 or LS ECU w/ the stock harness or an OBD-I to OBD-II converter harness (in which case u'll throw a CEL).

****, that came out all garbled and confusing.

In short: Yes, you can do it, no BS.

is it possible some one can give me a link so i can more info

Syndacate

Can you be more specific on what info you're looking for?

It's all plug and play - no wiring required. The harness will work. Everything will plug in and work fine.

As for the OBD thing, don't worry about it.

what do i do if the engine is is obd2 but my car is obd1

b20beast978

if you want to keep the motor odb 1 get a obd2a to obd 1 jumper harness and vise versa if you keep it obd 2

prodigee

i think you can just get a obd1 dizzy and injectors and you're good to go? well that's what we did to the b18b obd2.

yeah will i need to swap the dizzy and injectors even if i do the jumper

Correct. You will need injectors, dizzy, and alternator to do the swap. I just got done doing this to my car a few months ago. The only "wiring" you will need to do is for the knock sensor if you do the obd2 jumper (shitty idea. keep it obd1)

For an ecu, you can run a obd1 p75 (ls) for the time being until you get it tunned. If you do that dont beat the **** out of the car and lean it out as this will cause detination. If you're woried about that you can crush you stock fpr until you get a tune. that will keep you pretty safe.

as for the harness, its all plug and play, nothing to worry about at all. take it off the d15 and slap it on the b20. nothing will change.

You will want to keep the cat from your current setup aswell. you're obd1 so you only have one bung for an o2 sensor which is what you want. ALSO PLEASE READ! when you get the motor in the car, the header will nor line up with the car. you will need to take it to an exhaust shop and have then reweld a flange. not to worry, shouldnt cost anymore then $70.

what are you talking about knock sensor wiring can you elaborate please

kiddcarbuff

b20 doens thave a kncok sensor i dont think, so you dont need to worry about it, i know b18b's dont use one so i doubt a b20 uses one, so therefor you DONT need to wire for one since it doesnt exsist

...how long were you there for the b20 swap? yes there is a knock sensor and if you keep the car obd2 you will have to wire for it otherwise you will get a cel. If plan on ever putting a vtec head on the car (gsr) yyou will have to keep the knock sensor because the p72 uses a knock sensor reguardless of the obd. The only way you can completely void it is with a chipped p28.

BUT if u run the obd1 ls p75 ecu it wont look for a knock sensr, so therefor one isnt needed

HondaPartsHero

if you can get ahold of an 96up LS engine harness or CRV engine harness you won't have any wiring to do just plug and play even with the injectors, alternator and distributor otherwise you will need to rewire the B20 distributor, injector plugs, and alternator plug. You will just have some extra plugs on the B20/LS harness. I've always heard that the D15 injectors are lower flow anyways and the D15 distributor won't line up perfect.

BTW: If you need a P75 I have one I'll sell for very little. If It doesn't sell soon its going in the garbage.

YO I NEED THAT P75!!! PM ME
