I think it's direct bolt in but you have to remove the fuel pump or do a partial bypass to lower the psi to about 5 and change the wiring. Don't forget that you need a whole engine with the intercooler, AC compressor, etc.
If you have done engine swaps, easy. If you don't have any mechanical experience, difficult.
Engine would be direct bolt in but as mentioned, you'll have to transplant the wiring harness, instrument cluster, and pedal cluster. Depending on how bad the body is, I would consider taking it to a body shop or just living with it.
These cars are pretty simple so I'd bet it wouldn't be too hard. No immobilizer or anything like that. I'd rather just buy another car and sell the old one. The price difference isn't too high anymore.
