Its just way of differentiating between trims by VIN. The chassis code is still SW20. The JDM MR2 non-turbo is still regarded as SW20 btw. The "20" doesn't correlate to the engine size, take the AW11 for example. Some later models has the VIN say SW22 am I right?

In the case of MR2s:

AW11: A denotes the engine family (4AGE). W denotes the model (in this case W = MR2), and 11 is the generation of the MR2.

SW20: S (3SFE, 5SFE, 3SGE, 3SGTE). W (for MR2), and 20 is the second generation.

ZZW30 : ZZ (1ZZFE). W...etc.

I am pretty sure that is right.

SW21 was actually the chassis code for the 5S NA MR2. They had a completely different run of chassis numbers from the turbos and 3S NAs. Technically, a North American NA car is NOT an SW20...but people lump all MKIIs into SW20 for simplicity.

SW22 IS just a VIN designation for an SW20, but SW21 is not just a VIN designation for SW20 - it's the chassis code.
