80mm Same size as RB20/RB25 but has higher calibration. Should be good for around 350rwkw. Perfect swap into Rb20/Rb25 as bolt pattern is identical and no change is required. RB30 AFM plug fits which can be had very cheaply from any nissan/holden wrecker
Q45 AFM Nissan Infiniti Q45 V8
Wire 1 (White) - Signal
Wire 2 (Black) - Ground
Wire 3 (White & Black --have seen red and black--) - 12v Power
90mm Higher calibration and larger diameter airflow meter. Has been known to go upto 450rwkw. The physical body of the unit is larger and it wont fit standard pod filte adapters or airboxes. It is just over 3.5" in diameter on the outside. The inside diameter is 3".

Quoted from DocterOkay found some more clarity on this:
The MAF I have for sale is from a RB20DET or VG30DET motor. Part # on the MAF is 22680-16V00-AE36-000-N60. This is not the same as a maxima maf. Hence 350whp.
RB20DE(T)
Part # 22680-16V00
RB20DE(T)
Part # 22680-02U00
RB25DE
Part # 22680-02U00
VH45DE
Part # 22680-61U00
VH45DE
Part # 22680-61U01
VG30DE(T)
Part # 22680-16V00
Here are some further MAF information:

There is also an older 90mm Infinity Q45 maf good for 600whp.
Lastly, for up to 340whp the N60 (16V00) is said to flow more stable than the Z32 N62 MAF.
