sup i just got a 1998 Ls b18b what do i need to convert it to obd0? or should i convert to obd 1? cause i dont obd2 to much to mess with all right hit me with sum information....

 

get an obd0 to 1 conversion harness.. someone on this board makes em for about 160. then just plug in your obd ecu... you have to run 3 wires to the engine but thats not a biggie.

I converted my harness by hand... every wire.... I was broke. thats the ONLY reason i didnt buy the harness adapter.


-x m d

 

any more input to convert it to obd0? any info will help

 

I have a 91 CRX with a 96 B18B1 and I used all OBD0 parts, it's very simple. You will need a 90-91 Integra PR4 ECU, 90-91 Integra distributor, 90-95 Integra alternator (for plug n' play) then reuse your Si injectors and resistor box. Just reuse your Si wiring harness on the motor, you will have to extend a few wires and rewire the coolant temp sensor which is no w on the thermostat housing as opposed to the back of the block. Other than that it's pretty much straight forward and plug n' play.

You'll need to extend your map sensor wires which is a plus anyways. Ive always liked top mounted Map sensors better for readings and no fish tank check valves for turbos

 

Why he can still use his map...

 

Because the wires arent long enough to reach the top mounted TB sensor .

 

I know that but he can still use his Map.. You dont have to plug the one on the TB in

 

I know I was just saying if he chose too . I would recomend it over the firewall mounted one also .

 

I guess There all the same

 

Not if you plan to boost the car ..Its alot eaiser to use a missing link than check valves . Normally the top mounted map reads better also.

 

I guess this is just apples and oranges both ways work so its up to the owner

 

so i just need to extend my map wire? all the plugs from my Si harness will match up? use my si injectors rite? what about the 98 axles? i search but search doesnt come up with much... im lil lost still getting there tho keep tha info comin

 

you have to put new axles in for that swap.....i am not too familiar with the B18B swap. thanks. Oh, and how much did you pay for the motor and parts....pics?

Actually the stock MAP wiring will reach the MAP on the B18B throttle body. I installed mine without extending it, the wiring is tight but fine. It's been like that for about 3 years now, no problems.

You need to rewire the coolant temp sensor. It has moved from the back of the block where it is on your Si motor, to the thermostat housing on the LS. You'll need to change the plug to a normal 2 prong sensor plug. Other than that, you might need to untape a few sensor plugs and unloom them a little for them to reach the sensor, but that's about it.

As long as you are going OBD0, then all you need to do is reuse the stock Si injectors and resistor box.

You can reuse the 98 axles even if you don't use the hydro LS tranny. If you are using a B series cable tranny, all you need to do is change the driver's side tranny seal to a 94-01 Integra seal. If you are using the hydro tranny with the HASport EF hydro kit then no modifications are needed.
