i have an 89 civic that has a carberator and i want to put in a 88-91 sir-1 jspec motor into it and that is fuel injected.

what all would need to be done to switch it over.

 

Do you have a carb or is it a DPFI system?

There were no carb'd usdm 88-91 civics...that I'm aware of, anyway.
There were several different carb'd motors available in other markets.

 

the guy said the fuel cell something was out so i have to pour gas into the carborator to keep it running.

 

It is dpfi unless someone swapped in a carbed motor or modified it to run carbs which is highly unlikely. The car is most likely dpfi.

 

Best to figure out what you have...it'll impact what needs to be done

 

the guy i bought it off of said that to keep it running u need to keep putting gas into the carb cuz the fuel cell or something was bad. but anyways if it is carborated what all will i have to do to change it to a fuel injected?

 

You're not listening...
screw what the guy told you....it's not uncommon for moron mechanics mistake the dpfi assembly for a carb.

For us to tell you what needs to be done, we have to know if its carb'd or DPFI.

Changing from DPFI, which is already a form of fuel injection to the more desireable MPFI is relatively easy.
Converting from a full carb to fuel injection is much more involved.

It would help if you could tell us the trim/model of Civic (DX, LX, EX etc).
Go look under your hood and read what's on the top of the black, circular lid on the intake manifold.

 

go take a picture of the engine bay or something and post it. That way we can easily identify it.
