OK first off since you have mentioned that your Celica is a 1991 model we can assume you mean it is an ST184 (5th gen Celica) model. That being said I'm a little mystified that it has a 3SFE in it, as these were sold in Aus with the 5SFE (2.2L) in the first place. Perhaps yours is an import of some kind (ST182?), in any case I'll take your word for it that there is currently a 3SFE (2.0L) in there that was factory fitted.

The 3SFE and 5SFE are virtually the same engine, the difference (and hence the '5' instead of the '3') being the capacity - 3SFE is 2.0 litres and 5SFE is 2.2 litres. I believe the extra 0.2L was acheived by lengthening the stroke, the bore may have been enlarged as well but I'm not sure. So the 5S will have a slight low down torque advantage over the 3S, but that's about it.

If you were to fit a 3SGE as has been suggested, you would need the loom and ECU that comes with it as well, as the current 3SFE ones you have now will not suit. This will in turn require the car's wiring to be adapted as well. For ANY engine you install, it will need to be from a 1991 model or later, as the engine is not allowed to be older then the car. So if considering a 3SGE, you could only go for a Gen 2 one onwards. A Gen 1 3SGE from an ST162 ('85-'89) Celica will be illegal.

I doubt you would need to get it engineered (because of the different engine code it is a completely different engine as far as the authorities are concerend) as ST184's were fitted with that engine here anyway. Check with your state regs or ask an engineer to be sure. Other than that it should be a very striaghtforward swap and if your main reason for doing it is just to do an easy swap and get some spanner experience, I say go for it.

Hope that helps,
Matt
