Newly picked up project. Bought this from auction in MD. One owner vehicle. Well taken care of and original (except wheels) except then sat for many years. Only rust is on driver's side rear wheel well. All the body parts are original w/ vin.  

177k miles 5 spd GS model.

I got  this to have a project to do with my 15y son.
The plan is to clean her up, do basic maintenance, teach him how to drive a stick and potentially do some autox.

We are new to the wonderful world of Honda. So any pointers would be appreciated. I heard about obd0 - to obd1, mpfi swap, but my head is spinning.

Great looking car! Honda-tech.com was a good wealth of knowledge when I was more into honda's. It looks like the forum is still semi active and most of the old information is still available. OBD 1 conversion is good when you want to start tuning and adding performance parts past the basic Intake/Header/Exhaust. I have heard that many people are moving on to stand alone ecus instead of going obd1 though. Even the "newest" obd1 ecu's are turning 30 this year, and all of them will eventually need repair after the original capacitors fail. MPFI (multi point fuel injection) swapping should be unneccessary on your car. I believe all of the integras came with mpfi stock. It is easy enough to look and see if you have 4 fuel injectors or not.

In reply to Mrfurzzy1 :

Thanks for the info! Yes there are 4 injectors. I was thinking the stand alone was a better alternative.

     That fuel injection might be about the same as the 1985 Honda CRX that I have.   From what I understand, the main signal is the vacuum sensor (and RPM), all the other sensors then get to make smaller adjustments.  I replaced the old vacuum sensor with the next version.  I also adjusted the signal for the vacuum sensor, first with a variable resister, then replaced that with a regular resistor.  The vacuum signal was off due to the up-rated cam.  With a digital volt meter you can read the signal from the sensor.

    It's a old injection system, anything newer would be better, and easier to program or adjust.  But if you are creative you can adjust this system.

    You will want to add a air/fuel ratio gauge.

    Should be a great project.
