You're in over your head. At the very least, you would need custom-made engine and transmission mounts, custom driveshaft, some sort of ECU, and the ability to mesh the existing wiring harness with the new engine harness. Assuming that the transmission fits into our transmission tunnel and lines up with the shifter hole without modification, and that the engine will sit low enough to clear the hood without affecting the steering rack or underbody clearance.
You had better be an excellent fabricator and have deep enough pockets to buy your engine several times over, because that's about what it will cost.

See this is part of what I was looking to get out of this thread. The engine comes with an ECU and a wiring harness, but you're right I would need to get the existing harness to mesh with the one the engine comes with. As I mentioned in the thread, I have little experience with mechanics, especially engine swaps. I do know several people who do have the experience and even the tools necessary to do so. It would definitely be a learning experience, and I've got to learn some time!

Why!? The engine in your twin is fantastic. It's reliable and entertaining. Stock the SR20DET only makes 202hp....yah with a boost controller you can up the boost 4lbs and get more but all that work for maybe 30 extra hp!? No thanks.
Also, i'm not trying to troll, in the first post when listing off the parts you may need, you haven't even scratched the surface of swapping an SR20DET into a S13 240sx! If the 240 is auto you need a new trans mount and drive shaft. If it was originally a SOHC you need a longer throttle cable, radiator, a DOHC power steering pump and longer PS lines. You also need to cut holes for an inter-cooler and route the piping. These are just the things I can remember! Again...this is a few things to consider if you were swapping an SR20DET into a 240sx...a car that was DESIGNED to have that engine.
Check out NicoClub.com for more information. Most of the users on Nico are trolls but there is some good info on there.

The main reason I want to do a swap is to be able to hold more power. A friend of mine told a story of a guy he knew who turbo'd his BRZ, had Dynosty tune it to around 400whp and very shortly after cracked his casing. He said that the moral of the story to him was that the FA20 simply cannot hold that kind of power (there's still room for other explanations, the biggest being a bad tune).
As for the comparison of a 240 swap v.s. my FRS swap, most of those considerations are legitimate, if you're swapping it into a 240. But I'm not. While I will still have to take most of that into account, those are questions that can be answered rather quickly for my car.
Thanks for all the suggestions and considerations so far!
