Z32 Afm

[R32 Zilla]

What should i pay for z32 air flow meter ????

UAS have one for $400 , are they worth that much ?

I have called JMS and they dont have any and if they did it would cost $450.

is this for a GTR? if so i have also been told you can use the AFM's from GTST's

can anyone else confirm?

i was looking for Z32 AFM's a couple of months ago and they were very hard to find..

Why Do You need a Z32 AFM?

The Std. Ones with the ECU re-Mapped by Tilbrooks will make up to and over 220rwkw, as they alter the ceiling height of the afm's signal in the ecu.

But why not change it any way, i'm sure it will be limited some where especially with a gt2535. Fullboost around ?!?! 4200-4500.

My understanding is they are bigger (flow more air) and they have better resolution for tuning.... times that by 2 for a GTR and i think it would make a lot more of a difference than the standard AFM's would after tuning

so i shouldnt need a z32 one to make around 220 at the wheels?

Are you serious Joel ? 2535 -- full boost -- 4200-4500 !????! That surprises me i thought it would be sooner than that.

I had allways thought the std afm was maxed out at around 210 or 220 rwkw and iam after if possible 230rwkw as i have all the other gear to do this including nismo injectors. The only thing limiting me with this setup should be the standard internals.

Basically the Z32 and the R32/R33 is the same size etc appart from the signal that is sent from the afm.

I.e at 220rwkw the afm will send a 5.5v for example where as the Z32 will send maybe 4v.

I'm not really sure but tilbrooks said the AFM isn't a drama as long as the ecu has been re-mapped properly. I imagine that they alter the ECU to read the higher voltages or something..

I'm not 100% sure but I do know that Tilbrooks have made 220rwkw with an rb20det. Std Inj. Std Afm.

z32 afm's are between 250 and 350.

they are worth while joel .

my rb20 got to 92%usage on the rb25 afm I have using the vg30 turbo and I know a few others hitting simialr amout get oine 230rwkw whatsisname had to change the stock afm after 210rwkw or so.

The standard RB25 afm will hit maximum voltage at around the 180-190rwkw limit.

You can still tune a car, but it's a bit of guesswork, because the maps have to be fudged...

The Z32 will give you a better end result, with a smoother power curve, and better mixtures.

Thanks for the info everyone !

Meggala, where do u get z32 afm for $250 to $350 ?
