i want to do a b16b swap in my 93 eg but i wanted to know how to convert it from obd2 to obd1?

I think all you need to do is put on an OBD-1 distributor, OBD-1 injectors, and get an OBD-1 ECU. I put an OBD-2 B20 in my 94 hatch, and to use that OBD-2 motor, all I did was got an OBD-1 distributor, injectors, and an ECU. Everything bolted up and plugged in. Anyone else got anything to add? Im not sure if this works the same way with a B16.

if you get an OBD2 gsr or type r harness or an LS harness and add wires to, it will plug right into the eg at the shock towers then you can use all the obd2 componets(ie injectors and dizzy), then just get a chipped P28 with civic typer base map or get a CTR ecu and a jumper harness

I always use the stock engine harness and attatch to it. injector clips ect... is your eg an si model? if it is it should be prewired for vtec and knock no? should be easy peazy to hook it up. wire in the obd2 injector clips and try using your stock dizzy

egsleepercivic

the car is not prewired for knock, it will be wired for vtec only if it was an ex or si

so to make it obd1 i would HAVE to change the injectors and distributor i know about the ecu. but lets say im getting a compete swap would i still have to change those things?

Yeah, but the knock's useless as **** on a bull - if you plan on running a chipped OBD-I ECU or an OBD-I CTR ECU - run it on a conversion harness and worry none about the knock sensor hookup.

VTECdohcter

would i be able to use the stock ctr computer and make it obd 1 and whats the knocked sensor.

Bump!!!

Thats exactily what I did, just keep in mind that Type R Injectors are different from non Type R (RS, LS, GS, GS-R all the same)

VTECdohcter

so all i need is the conversion harness

Slyfox_racer

just get a jumper thats the easiest way

VTECdohcter

but is it going to run right i dont want to have any problems?

VTECdohcter

Bump!!! need to know tonight

keep everything OBDII from the engine bay, its the same exact thing as OBDI with additional plugs(the plugs themselves are different as well). just plug in your OBDI ECU of choice and voila....

I'm running a OBDII harness from the shock tower foward with a OBDI ECU.

as long as dizzy, injectors, alternator etc...are obd 2 everything shall be plug and play. all you will need is a obd2 to obd 1 jumper harness

The alternator plug is different from OBD-I to OBD-II?

VTECdohcter

so i would need to change the alternator plug or what?

DOHCtorTHRUST

if you have both OBDI and OBDII altenator, just open it up and use the corresponding housing to match the plug.
