Air Flow Metre's

[mark morris]

Hi every one,

I am looking to up grade the AFM's on the GTR and I not to keen on getting second hand ones that may give me trouble shortly. But in the same breath, I dont want to cough up the $750+ each that nissan want for the genuine RB25 AFM's.

as im only looking at making about 300-350rwkw the RB25 AFM's would be sufficent, but will go with what is best at the time.

Just wondering if any one could answer a few questions I have?

* Dose any one make after market or equivilent of the RB25 AFM?

* Dose'nt Bosch make the Z32?

* Dose any one have part no.s and/or prices for RB25, Z32, NISMO etc. air flow metres?

Cheers, Mark

I was in the same boat but just bit the bullet and got z32 brand new. Not cheap but new. I even changing the airflow meters don't go rb20/25 meters. Sure they're 80mm but bugger all difference in electrical callibration. Same with Nismo 65's(They are supposed to be rated at 700ps a pair-crap).At 330kw at wheels my GTR maxes air voltage around 3.5v. Plently more left and sill idles good. Gotta chop/replace the plugs though and get 80mm z32 specific gtr filter kit (eg Apexi super suction) Prices each I've checked:

RB20/25-$200 s/h

Z32-$250-$450 s/h or $600-$800 new

nismo-$400 new

My advice is to stick with stockers until you max them out on the PFC then get z32 units, unless you get the rb25 ones for a really good price(they plug straight in). Depends on how much kW you are stopping at.

350kW rb25 afm will be close to max.

As a bit of a side question.. Anyone know where to get a 2into1 airflow meter adapter for putting a big single onto a gtr? I've seen them before, I think GReddy make them?

Where can I get one and what are they worth?

Cheers.

[mark morris]

Sorry robbo cant help you with that one. except that I would probably just get one fabricated?

Any one got a z32 afm they can cross reference that number for me?

Cheers, mark

Z32 P/N: 22680-30P00

This paper came with my Nismo AFM's, it's compares the GT-R, Z32, and Nismo voltage curves.

Thanks sav man! wonder what the one I have here is?

Could it be a Bosch part no. not the nissan number?

The GT-R, and Nismo AFM's have Unisia Jecs on them, dosn't say bosch anywhere. I havn't seen any Z32 ones to see what they have on them.
