I have a ls/vtec in my 91 integra. And i have a p28 ecu on the way to run it hopefully. well since i have to use a jumper from obd0 to obd1, i heard that there are alot of things i have to change and here they are:

****Depending on the type of engine transplant you are performing (B or D-series), you must get these respective B or D-series parts in order to complete the OBD1 conversion which in turn, will satisfy the OBD1 ecu's programming.

- Obviously you need an OBD1 ecu..
- An OBD1 distributor
(B or D-series depending on the type of engine transplant you're doing, if any)
- OBD1 distributor male plugs
(they're all the same style for civics and integras)
- A 92+ civic/integra 4-wire 02 sensor.
- A 92+ civic or 94+ integra Vehicle Speed Sensor aka VSS.
- Lastly, an OBD1 thermostat housing w/integrated thermo-switch sensor.

... these parts are all needed in order to complete the OBD1 conversion along with rewiring and implemenation of OBD1 distributor plug(s).****


I GOT THIS FROM JDMHONDAPARTS.COM CAN SOMEONE TELL ME IF ALL THIS IS CORRECT.

 

BUMP

 

bump please

I did not do these two and mine is alright.

 

yep..those 2 items are optional.

 

how do you convert my stock 1 wire o2 sensor to a 4 wire o2 sensor? i know it's probably a tough question to ask with seeing it but, please try to explain this to me. thanks

I don't think you can... The 4-wire sensors have a built-in heating element which gets the sensor hot & working faster when you start up. You need to get a heated O2 sensor.

 

You cant convert an obd0 ecu to use a 4-wire O2. You will need to get an obd1 ecu first.
