EDIT: I was under the impression that the maximas didn't switch to the VQ35 untill 03'. Sorry about that. I'll leave this up for the VQ30'ers out there.

The VQ30 is an excelent motor but it has little aftermarket suport. The rods are good to about 450hp(it's rare but it has been done) and it's shitty high-comp pistons make tuning a nightmare. Your on your own for forged the rods, I've yet to find a dealer for them. For the pistons you can go to BRC they can get you out the door with low comp pistons for about $850. Here is a copy of the e-mail I got from them about this subject

It would seem that you are planning to run a turbo because you are lowering
the compression ratio.
Is this correct?
With all of that out of the way, the price for the pistons would be $536.00
in any compression ratio.
The price for pistons, pins, and rings for a naturally aspirated engine will
be $735.00.
The price for pistons, pins, and rings for a turbo charged engine will be
$835.00.
The build time is approximately 2.5 weeks from receipt of payment.
The piston to cylinder wall clearance is 0.004", which means that you may
hear piston slap on start-up.
If this happens, do not rev the engine to put heat in it. Just let it idle
to temperture.
If hearing the noise of the pistons will annoy you, then I suggest you stay
with stock type pistons.
My last statement is only due to past experience with customers.
There is always one out there that wants tons of power, but must be kept
quiet for daily driving.
If this is your concern, I ask you to think hard about your decisions.
If you have any other questions, please feel free to ask me.

Just some things to think about. Happy tunning.
