Without having to take the 09 motor apart I decided to buy a new oil pump.  This is to find out what pump is in the Newer FWD VQ’s.

Summary

The 2009 Maxima oil pump is $31.17! I was amazed by the price of this oil pump. All of the other VQ pumps range from 180-220. So why is this oil pump so cheap? Well the casting looks cheap with lots of flaws. One thing i noticed is there is a lot of play in the pump you can simply shake it and hear the gears hitting the case. Now this pump is brand new and the others are not. This 09 pump is the only one that has the “looseness” like that.

The weights are as follows:

02 Maxima O- 132 I- 158
09 Maxima O- 126 I- 160
06 ZRevUp O- 134 I- 166

All weights are in Grams.

As you can see the outer gear on the 09 has the biggest difference, this might be why the pump cost so little. The inner gear is not so big of a difference but its still 6g lighter than the rev up

All of the springs look the same, they all have 15 coils. And feel the same but I don’t have any way to test the springs.
