In case you meant engine codes, it works like this.

2JZ-GTE

2 - Revision # (2nd revision)

JZ - Engine Family (JZ Series)

G - Head Design (G = true DOHC setup tuned for higher HP. F = scissor gear-type DOHC setup tuned for more torque/economy.)

T - Aspiration (Z = Supercharger. T = Turbo. Absent in case of n/a engines.)

E - Induction (E = Fuel injection. If there is no E, then its carb'd)

3S-GE = 3rd revision, S-series engine, DOHC, fuel injected.

4A-GZE = 4th revision, A-series, DOHC, supercharged, fuel injected.

It would have been nicer if they followed Nissan (or basically any other japanese manufacturer) with their nomanclature which designates series, displacement, valvetrain, fuel injection and number of turbos RB26DETT, VG30DETT, SR20DE, etc.

1JZ = 2.5

Block size... measured from where to where...?
I've always read it was the engineering revision number

Correct. The perfect example is the VZ block v6's. 2vz-fe 2.5L 3vz-e/3vz-fe 3.0L, 5vz-fe 3.4L

The block numbers come from changes to bore and stroke. Normally the lower numbers are the smaller motors, just because its easy to start small and work your way up. The block often slightly changes when going up in number, but its generally the same. (the 3s and 5s blocks are almost the same on the outside)
