Mark. My mate has a 4G63 non turbo front wheel drive engine turned to rear wheel drive in a onld Mitsubishi Galant station wagon. This was very early 1990's when he built it, every one said it could not be done. Haa haa he showd them, bolted almost straight in, custom extractors was the only problem.
To run his puter he had to add a lamber probe to the exhaust dump pipe, at the same time as he had the threads welded in, he had a extra thread added so he could use another lamber probe, attached to the flashing light style kit you can buy, and build through autonics. When he isn't tuning the car, he removes the extra lamber probe, and bolts in a bolt to take the place of the extra probe. He seemed to get it running as well as any one else could. Mind you he spent lots and lots of hours with the laptop on the passenger seat. He was running a Link, computer setup. Later.
