    Former Maxima owner, and lover here also.

    Negative. Ones a VG30DETT, and the A32 gen Maxima uses a VQ30DE, which was the predecessor for the motor in the 350 and various other Nissan cars today. Same displacement different motor.

    The older, gen pre-1995 Maxima (A31?) shared a the same VG designated motor as the 300zx, but I believe there were some differences between the two.

    True, but also consider this:

    VG30E, not the DE, was used in 84-89 in the 300ZX AS WELL AS 84-94 Maximas. So if the OP has a VG30E block laying around and the 300zx he has is an 84-89, then again the answer would be "yes". Right? Eventhough the 300z moved up to the VG30DE in 90, it still maintained the exact same bore and stroke and displacement of the previous year's VG30E, so therefore it would also possibly be the same block, possibly same heads, just different intake manifold. Again, there are many possible variations like this where a "Maxima" motor is indeed very much like the "300zx" motor so it MAY be the same block too. Follow?

    As explained above, there are some differences in some of the VG's but it may not make a difference in respect to the BLOCK and possibly the heads.

    The chassis code is J30. A31 is a RWD Cefiro chassis code.
