yo guys my buddys older brother totalled his 2000 LS integra w/ GSR Tranny and is now selling me the whole front clip of his car which should be the complete swap..

i was wondering what do i need to complete this swap into my 1995 EG hatch CX?

i hear alot of things about OBD1 to OBD2 difficulties and im really new to this so please give me some light..

im from California and i would want this engine to be BARed so no short cuts...

You'll need an OBD1 ECU, thats about it. Use the OBD2 integra engine harness, its a direct plug in at the shock tower plugs. Then simply run an OBD1 PR4/P75. Below is a couple of diagrams to help you out.

This should be fun swap, especially having the cx which is super light. I had a cx with b16a boosted and that **** kills. Just got a dx and trying to make it lighter to cx weight. Please post a build thread when you are going to drop this bad boy in.

you will need to run a jumper harness to run the OBD2 p-75

Don't install a jumper harness, simply install an OBD1 LS ECU and be done with it.

so all i need is the OBD1 LS ECU? and just take everything from the LS to my hatch?..

and shouldnt i retain the original ECU that came with the car or i dont need to? i plan on BARing this vehicle. i do have all the smog components from the integra and will be swapping it into the hatch also. just worried since the car came from a ODB2 and i will be making it OBD1 blahh im confused lol.

If you're planning on BARing it, you won't be able to pass if you have a conversion harness or anything - I think.

I have always wondered this. Where he is going from new to old can't he just use a obd1 intake mani(complete) obd1 p75 ecu elimante the crank sensor and voila???? done...It would be a direct plug and play no f*ing around but will obd2's run without the crank sensor?? just a question...

You never mentioned the whole California thing. I think it depends on the ref. I have heard reports that you have to convert the car to OBD2 before, I've also heard that its permissible to run an OBD1 ECU. I'd talk to a ref and see what he/she tells you.

yeah sorry i am from the Gay Honda state of California.. uhhh i talked with a ref this morning and he said its better to have the the newer engines ECU so i would have to stick with OBD2...

Its better or its legally required? Cause running an OBD2 LS ECU (unless you get one from a '96 - '97 'teg) looks for a fuel pressure sensor the civic doesn't have, requiring you to swap in a fuel tank from an EX civic or Integra with a FTP sensor, along with a bunch of other evap stuff, secondary O2 sensor, CKF sensor and potentially some other stuff i'm forgetting.

im getting a basically an integra with no exterior parts or interior parts just the engine and stuff that makes it run lol.. so anything that came with the 2000 integra LS im getting..
