No. Do you plan to use your EFI on the Carbed motor or adapt your current car for the carbed motor. Either way it will be a nightmare. What year and model is the carbed motor from.
It 1991 but would i need to change the crank shaft on them

Ok so '91 to a '91 maybe. I assumed you would be trying to install an older motor not one from the same year, my bad. Do you know the exact model numbers of the motors or what the carbed motor is from. There are multiple cam part numbers for these and I just need to see what the difference is. Since the dist on the carb and efi cars are both ran off the cam in the same spot I would not think that they would have changed the placement or cut of the gears on the cam.
yetilikesbeer is spot on. The 1.6 4A F DOHC narrow angle valve engines in Corollas in 1991 have 'bucket' tappets, or lifters... and if the cam is worn or wrong you (or your mechanic) can use shims or grind the cam to get the tolerances back where they belong, it would be an 'iffy' job that you may well end up spending a lot of money and still be right back where you were.

I just saw your second question, asking about having to change crankshafts. The answer is yes, the crank will have to be swapped or if not that the piston rods will...the 4A FE ans 4A F have a different stroke, jeeez, dude, I'm all for going the most inexpensive way too...but get a crate motor or a good used one, from a car that was crunched from the rear. Then your 1991 will take you another 150,000 miles and not have a frankenmotor built from "iffy' parts...and the time and money spent would get you in to a 2000 CE for $150 a month.
