Q45 or Z32?

[GTR 94]

as the tittle states i was just wondering what AFM are prefered and recommended. i am looking for somthing that is straight swap or least difficult to adapt with standard GTR AFM and i am tossing up between the Z32 and the Q45. so far i have found that they are booth pretty much on par.

any suggestions? thanks

the Nismo AFM's are a direct fit Lee

get new ones, saves having one ppossible pack it in and cause dramas

The Z32 is an 80mm & the Q45 is 90mm they both pretty much do the same job.

Or option 3 as Nismoid mentioned.

cam, it was more.. which will just swap over with stock gtr afm's... my guess is as nismoid said.. dunno wat the plugs on standard gtr afm's are like but yer... z32's tend to be a common upgrade on gtr's from wat i have heard

Warrick,

What was more? what will swap with what? :confused:

The plug on a Z32 is 5 pin

the question was more 'which will swap straight over' and ****ed if i know wat gtr afm plugs are standard... *shrugs*

[R31Nismoid]

do Z32's fir the GTR plug?

i know the nismo ones do

Hi GTR94, if you had done a search you would have found out that GTR AFM's are 65 mm. A search would have told you that Z32 AFM's are 80 mm (same as RB20/25) and Q45's are 90 mm. By doing a search you would have noted that NONE of them are a straight swap over. They won't fit the airfilter box or POD's for a start, as quick search would have shown. The ECU will also need retuning, as per the search results.

PS; did I mention that you should do a search?

Hey guys, I thought the VG30DETT Z32 6pin orange AFM's were 76mm?

That's ID, they are 80 mm OD. It is Nissan's convention to measure AFM's by their OD.

it all depends on your rwhp level you want to run

my first

first choice

good up to 540rwhp and around $150ea second hand

rb20/25 are straight fit (same plug ) but will requires sum piping mods and tuning adjustment

second choice

good to around ~700rwhp and around $300 second hand + $30 plug

Z32 require a different plug solider in and the same piping as rb20/25 and a larger tuning adjustment

Q45 i have only seen on one car that was a 1100rwhp drag car(apexi's car)

all are relative easy to fit when running APEXI PFC as you can select afm at the touch of a button

cheers

i was under the impression that the nismo items are a direct fit... am i wrong?

time to make a phone call

[Alf]

The difference is........... sticker or no sticker, my new Q45 maf was $450 fron Nissan japan, I believe Nismo charge more to put a sticker on :bs!:

[GTR 94]

well guys thank you for all the feed back greatly appriciated

and Ash did you get a response on those nismo ones?

[Sydneykid]

There are 2 issues with AFM's, one is the restriction caused by the small diameter. The second problem is the one you hear about most often and that is the calibration of the hot wire sensor for higher airflows.

The Nismo GTR replacement AFM's I have seen are the standard GTR diameter (65 mm) with what look like Z32 sensors inserted into them (replacing the standard sensor). This fixes the calibration problem, but does nothing for the diameter based restriction.

[R31Nismoid]

there are a large number of cars running upwards of 330rwkw here in Vic now with the Nismo items.

They have no problem and results arent too dis-similar to others with say Z32's.

every car is different though.

Lee - will find out Wed
