It will all fit in fine, you will need the engine, loom, ecu, etc... basicly a whole half cut. The transmissions are compatible as well. IMO you will be wasting your time doing it, a 3SGE beams is a very expensive engine, and then there is the cost of the swap, etc. also, in QLD at lest you cant do engine swaps that require a mod plate on your p's. the 3SGE is a good engine, if you did some pretty basic mods to it you would be able easily get more performance from it. Save your cash and once you are off your p's do a 3sgte swap. Blacktop BEAMS is RWD remember, so there may be a bit more work required - redtop BEAMS might be a better option as it is transverse layout in both the ST202 and SW20. yeah that is a good point, the blacktop may require a east-west sump, oil pickup, etc... maybe different mounts and stuff too.. the redtop would be a better option if you were going to do it. regardless though, it would be an expensive swap (moreso than a 3sgte swap) and you would not net that much of a power gain from it. yeah, after pricing more MR2s its looking more like an engine swap will be a no go till i get off my Ps. but in that case, what would be some decent upgrades to do to the stock 3sge?
