2.5L TBI vs MFI

Ive got an 87 comanche with the original 2.5L TBI engine. About 4 years ago I lost a cylinder and its been parked since. The other day I picked up a 2.5L MFI out of a 92 YJ Wrangler to go in it. My question is, how bad would it be to convert the 92 engine to throttle body injection, or how bad would it be to upgrade the truck to match up to the multi port injection. It had been so long since I looked at my truck I didnt even think about the fuel injection differences when I got the engine out of the YJ.
