obd0 to obd1 question
I have a b16a in my crx and i was wondering if switching over to a obd1 ecu would benifit it? I've heard i'd have to change like my spark plugs,wires,cap, and rotor. thanks

Not really... Not unless you want to boost or do nitrous and then need a fuel managment setup... Theres more options for fuel management with OBD1... But otherwise, its not worth the trouble... But even then, theres still plenty of options for OBD0, so even then its probably not worth it... Now a D series VTEC swap into a CRX is a different story... Only worth the trouble if u do convert... But thats only cuz theres no compatible ECU to run those engines in OBD0...

It is pretty much engine management purposes. I was thinking of doing the same thing. All you have to change is, get a OBD0 to OBD1 conversion harness, new injectors plugs and injectors, OBD 1 distributer, OBD0 to OBD1 conversion plugs for the istributer, and a new OBD1 ECU. You will be set.

Yea really dont even NEED injectors from an OBD1... The OBD0 injectors will run fine on an OBD1 ECU if u keep the resistor box... So to keep costs down, you can keep the injectors, clips, and injector box... Which if your converting for fuel management, and are intending to boost, most of the larger injectors (DSMs and such 440cc) need an injector box anyways since they are peak and hold injectors...

Most of the turbo setups Ive seen use DSMs with peak to hold injectors... Mainly because theyre cheap and do the same job as more expensive aftermarket injectors... So I should have said most larger injectors that people upgrade too are peak to hold... Plus they respond faster than saturated... And either way u slice it, most cars do come with saturated injectors, infact most that dont are turbo from the factory... Which we all know is a very small amount of cars on the road...

you'll also need a four wire o2 sensor. from an obd-1 car. (i think an obd-2 one would also work). and you do not need to replace the injectors. unless some one can prove me wrong. i did this swap without changing the injectors, but i have a set of obd-1 injectors laying around. if someone can explain to me any advantages with the obd1 injectors, i might consider doing that.
