So someone can actually find, on a used car lot somewhere, that exact combination of long"block", intake, induction, fuel injection, and engine management (except as allowed otherwise by the ITCS) as everyone is running in their ITS RX7s?
Remember:
Ergo, if Mazda did not deliver that combo, it's not legal.

In a word, yes. My car and all the ones I have worked on are 89-91 spec all the way and it is the fastest setup and the process weight was set for the high side of the power of that car.
Now I will play your word game. If the rule states that the motor, trans, induction must be updated as a complete assembly then they are different from the later/earlier original so were never delivered from the factory that way. They are specifically different because they may not interchange parts, but were allowed to be changed as entire assemblies. Until the vin rule all of these parts were illegal if we use your assumption because the XYZ motor does not match the vin. But the rules say we can install that longblock. I call that cut and dry that the assemblies could be matched. How do you explain it?
