Depends on if there was any major changes between the model years. If the engine code is the same, it is usually doable. However, the big issue is more of if you’re in an emissions testing state who has it in the books the engine MY has to match if it ever fails. If it does, then you can’t legally do it but on the other hand if it has to match emissions, you need to make sure that will not be an issue. Not that they would/should know unless the person who did it opens their mouth ;).

It’s not a concern in nontesting states where the license plate is the certification, but if they actually test it then you may have a problem if it isn’t 100% exact.

It’s not a concern in non-testing states where the license plate is the “certification”, which most are thankfully. But if they do actual tests, you have to see what the books say about it, or just keep a sealed mouth about it.

Compare the 1991 engine to his blown 1993 to make sure. The other gotcha is if the 1991 engine has less power then the 1993, the pre-2002 Toyota ECUs were WORM based (Write Once Read Many) so you may run into an issue if the tune doesn't get along with a 1991 engine. It's not a likely issue, but it's a potential problem that you need to watch out for. If you run into an issue with a 2002-present ECU, one can reprogram it to work with the swapped engine but for one of these the tune you get on it is what you're stuck with.

Compare the 1991 engine to his blown 1993 to make sure. The other gotcha is if the 1991 engine has less power, and the older Toyota ECUs (pre-2002) are WORM so you may need a matched ECU if there’s any changes that matter, especially the tune. It likely doesn’t matter but keep that issue in mind. On the flip side, if you run into an issue with a 2002-present ECU, it can be reprogrammed so those aren’t as bad.
