its a 1992 model ibiza cant get a replacement engine

Hmmmmmmm any engine will fit in any car BUT you may have to change engine mountings, upgrade brakes suspension and possibly other ancilleries. But bet is to ask a dealership and get a scary quote as your worst/best price quide but engines are available you obviously havnt looked enough seems your a wanna be boy racer on a budget with the mechanical intelligence of Mr Bean so I'd really say DONT DO IT check out seat cupra at http://www.seatcupra.net/forums/ The Beannie there will square you out

Now for a PROPER answer for you . In this case I think you are going to be lucky, to the best of my knowledge a Cordoba is very similar to an Ibiza but it has a booted body instead of a hatchback but as far as I am aware all the front end design of the engine compartment is identical. I see no reason therefore why the engine wouldn't fit but this is on a like for like basis eg say your Ibiza has a 1.6 engine then a 1.6 Cordoba engine from a car of the same year should fit, but if the engine capacity or year is different then there may be some difficulties but it may still be possible to overcome these with advice from a competant mechanic.

It should - they are essentially the same car from nose to rear doors.However, make sure they are the same specification of engine, or you'll need to change a bit more than just the engine (engine-mounts, transmission, driveshafts, instruments, ecu, springs and dampers, etc. will be different for different engine specifications).

Yeah, they are the same car just a saloon shell. i,d bet the vw polo or golf engine would go in as long as they are the same size c.c and decade. They are built and created by vw. just built in spain to lower the prodution costs. most components are vw have a look around your car stamped with vw on nearly every part.
