Nismo Afm Or Z32?

[stunnd]

Hey guys,

Im thinkin about gettin bigger AFM's but dont know which one to go for.....which would you use Nismo or Z32? i was gonna get Nismo because of convenience but a workshop told me to not waste my time an to go for the z32's but then i would have to change the piping that connect to the AFM's.....

Does anyone know how much that will cost or who to recommend in canberra to do the piping?

Cheers guys.

Easy, really.

If you want to run a stock airbox go the Nismo units.

If you are happy with pods (particularly Apexi ones) the Z32 option is probably better. You can get a ready made set up from Nengun. http://www.nengun.com/apexi/super-suction-kit-z32-80mm-afm

You can get the pods to run with the 65mm units, too.

So theres actually a difference between em? hmm... learn something new every day

I thaught the Z32 bosch unit actually is the same fit as standard but just fatter? Maybe only R33's

yeah im running apexi pods at the moment but i dont think its the same ones in that ad....does that kit include the pipe that goes from the pod to AFM and AFM to turbo?i cant really remember what they look like as i have only had the car on the road for about a 2 weeks in the last 10 months.......

It depends what you want to do with your car. If you only want up to 350kw at the wheels then you can use the green label r33 gtst a/f meters. If you want over 350 then go the z32's as they have more resolution, What this means is it takes more air to max out the 5 volt peak that a/f meters use.

I haven't had much to do with the nismo ones but if they are 65mm then the other two options would be a better choice and i dare say a lot cheaper.

Both a/f meters will fit the standard rubber hoses they are just tight going in. The air pod pipe will need to be changed as the four bolt flange is obviously bigger on the 80mm ones.

Also if you have a power fc then you can change the settings in the computer for both gtst and z32 so that you can drive it to get tuned.If its still the standard ecu then it will need a new tune burned for it

Hope this helps

There are a range of pod filters that fit different sized AFM's. So have a look.

The advantage of the Apexi set that matches the Z32 AFM's is that you can bin the rubber hoses - these when old/tired have been known to suck in & restrict flow to the turbo.

AFAIK there is no difference between the range of the Nismo units & the Z32 units, just the size of the housing.

Irrespective of which unit you choose (Z32 or Nismo) you need to recalibrate the ECU. On a Power FC this is easy, but it is still worth checking the AFR's on the dyno once the job is done.

Make sure you get some plugs to got with the Z32's AFM's. You need to splice these into the wiring of the car. Can anyone confirm if the Nismo unit is a straight plug in, it the same as the stock plug?

nice one, thanks for the advice fellas.......

now i think ill go for the z32's but theres another question i need to ask.......

what are your thoughts on 2nd hand ones? i know im beta off goin new but i can get a pair of 2nd hand ones for $500.....but im affraid with the luck ive had that they will f*k out on me, as usual........

but do z32 AFM's have the tendancy to f*k out?

[djr81]

My thoughts on second hand AFM's extend as far as don't buy them. No further.

You can either get proper, new ones or the Bosch equivalent. If you know anyone who works in the parts trade you can probably get the Bosch ones quite a bit cheaper.

By the way, as far as I understand the RB25 AFM doesn't give much additional top end over the RB26 units - this despite it's larger diameter.

There is another thread somewhere on the net - maybe SAU, SDU, SOf*k or Nicoclub, can't remember - where they talk about counterfeit Z32's. Apparently there are new dodgey copies of Z32's out there and its buyer beware. I'd suggest giving eBay the flick, buy from a reputable business like Nengun, Greenline, Just Jap, Kamikaze or other ones that sell on SAU etc instead. At least they will stand by their product.
