So at that point, it would only be modifications which would be illegal correct? If you had a stock SR or RB, and it could pass smog, you would be completely legal. My question is, because as far as I know, only GTR's have been made legal in the US, at least that's all Motorex sells. Does that make the entire RB series legal, or only the RB26DETT because technically they are different motors, just the same block.
