Which engine to get for damaged 5SFE? Options

[FlyingBoat]

I think I have a hydro-locked engine from my son running it through some high water. It is 95 GT Conv, manual 5SFE with about 70K on the engine and 120K on the car.

I see some rebuilt 5FSE's on ebay for $1200 shipped including return of core. That seems a better deal than a 60K engine for $800 or so, correct?

I guy here in town has a used 5SFE from a 3SGTE swap for $500 with auto transmission, but doesn't know the miles, lol.

I am more interested in economy than performance on this car, so I don't think I want to go the 3SGTE route.

I was thinking maybe someone else out there might have a low mileage 5SFE they might want to swap out.

I found out for sure today that the engine is toast.

I see a nice 5SFE for sale that is rebuilt from a 91 MR2.

Anyone know how much extra work there is to get this to work in the Celica? I saw someone said on this thread that the Celica takes a different oil pan. Any other issues?
