no, it will just add power.
You have to remove the engine and gearbox. you will need a engine crane. Once you have the engine and box out, remove gearbox from engine and replace clutch, Refit gearbox to engine, put engine and gearbox back in car. Easy job if you have access to a engine crane.
The gearbox will physically fit, you need to change the clutch to a push type clutch however. If we are talking 5 speed gearboxes.
The basic engine itself is the same L-series used in the 600, however you will need to use the 600's gearbox (because of different ratios) and diesel pump and injectors. Other than that, it should be a straight swap.
The mountings on the top will differ. It should fit the engine ok, but you will need to fabricate a new cradle to match the car's gearbox mounting position.
No is the simple answer. You need to change fuel tanks, fuel lines, the engine, gearbox, driveshafts, engine/dash wiring loom, ecu's etc etc. Definitely no.
You need to remove the transmission oil pan. Use an oil pan to catch the old fluid that will come out. Replace the filter while the pan is off and replace the pan gasket.
Yes, albeit new engine and gearbox mounting need to be fabricated.
There are hose repair kits available, but you are much better off by replacing the hose. Don't forget to top up with antifreeze after replacement. The Rover may need bleeding afterwards, the bleed screw (8mm) is located on the water rail going over the gearbox. attached to the engine block
it will fit fine, though you might need to swap the clutch release bearing and the cover plate.
Only if it has a completely different gearbox (with overdrive) fitted. You would then have to find an engine to fit the gearbox. You may have problems fitting this into the bodyshell, so I suggest you source a secondhand body from a car that will fit the engine and gearbox. Maybe you could fit the body from the car you took the engine and gearbox out of? Then all you need is an interior, driveshafts, brakes, wheels etc. and the job is done!
With considerable difficulty. You need to split the engine from the gearbox and remove the clutch to get to it. This'll mean getting the engine out of the car.
YOU NEED TO HAVE BELL HOUSING FROM CORTINA IF IT FITS GEARBOX IT WILL FIT IN TO CORTINA IM ASSUMING THAT THE CORTINA IS A MK11 IT ALSO HAS TO BE OF SAME YEAR. ALSO CHECK RATIO OF GEARBOX YOU WILL HAVE TO USE THE GEAR STICK FROM GEARBOX AS THEY ARE DIFFERANT THREADS HOPE THIS IS OF HELP KIFF which model of escort? which model of cortina? If the engine is the kent crossflow type in both vehicles then the gearbox will fit either engine
