Safcii Or Z32afm?

[johnblack33]

just a quick question... am i right in saying that if u have an safcII u no longer need an afm??? or am i completely wrong.. as i tihnk i have read this somehwere... as the safcII will control all ur air flow readings thus no longer needing the afm... if so wat would i be better off purchasing.. an safcII or a z32 afm??? cheers JT

What are you planning on getting out of it?

You only need a bigger AFM when you are pushing more and more power (1 of the other guys will clarify when you will need the Z32)

yeh alot more power... just reseearching now but eventually... btw greg.. im in need of another cooler off ya man are u able to post them out or pick up only?

[paulr33]

to use a z32 afm you need safc or aftermarket ecu or remapped ecu.

z32 is only required for 250rwkw and this is due to voltage restriction and not "size" restriction as the z32 is the same opening diameter as the stock rb25 unit.

your car will not run as a good and wont be as driveable with a map sensor setup if thats what you are thinking of. you need an aftermarket ecu that supports map sensor to get rid of the afm, such as motec, powerfc djetro, microtech

I'd go with the Z32 and get the stocky ECU chipped or get Power FC.

$175 for a cooler delivered within Vic.

PM me or email me.

cheers,

[GKTECH]

wolf3d is the same as powerfc and others. no timing cut on gear change

car sounds stock to me

safc, based that its the cheapest and will do the job as good for a stocker car

Do both mate! Grab a 2ndhand Z32afm from these forums for $200 or so, and a new SAFC II, and have them tuned at the same time.

I found at 141awkw my rb25 afm was reading near max volatges on the safce, so having it retuned today for a Z32 afm.

There is no way an RB25 AFM is maxed @ 140rwkw.

Everyone does 190rwkw which is the limit of the turbo (give or take)... there is still more in the AFM

Dont get a 2nd hand AFM anyway, not worth the hassle if it starts playing up.

Which, after 10 years is highly likely

R31, after the tune at 141 All-Wheel kw the voltage on the stock rb25 afm is 4.95Volts, I was told 5.06 (or 5.16 by memory?) was max.

The tuners said if I want more power, then with the next mods a Z32 afm was needed, so I found a good condition 2ndhand unit and its being retuned right now along with other parts.

I just hope it works!!!

[R31Nismoid]

what motor is this on?

[Tangles]

Ive got a March 1997 Nissan Stagea RS Four V, automatic, with 4wd attessa system. RB25DET has done 82000kms and replaced timing belts etc, at 80000kms along with major service and mods.

All parts have been installed now, just the SAFC needs a tune, tomorrow. Ashley at Graham West Workshops (Marion, Sth Australia) has cleaned the Z32 AFM with contact cleaner, and said it works just fine and is in good condition (luckily!! I was worried after your post about not buying 2ndhand Z32's afm's due to wear / tear).

Here's a list if you're intrested R31Nismoid (Ash?):

Dayz special edition Stagea RS V Four

Clarion stereo tape unit with 6-stack cd player

Clarion amp

Clarion subwoofer

Pioneer 260w front door speakers

Eclipse 80w rear door speakers

New Oxygen sensor

Bosch 040 fuel pump with direct battery feed at 13.8volts

New high pressure fuel lines

Nismo adjustable fuel pressure regulator

Nissan Z32 Air Flow Meter

3inch JustJap stainless steel single dump pipe system

3inch Catco high flow catalytic converter

3inch Dayz edition cat-back exhaust system with quiet muffler, all in aluminium coated mild steel

K&N pod filter in custom enclosure, replacing soon with BMC panel airfilter and standard airbox

Apexi 'hybrid' front mount intercooler with custom pipe kit

Hybrid dual stage Electronic Boost Controller, set to 10 & 12psi (after this current tune)

Apexi boost gauge

Apexi SAFC Super Air Fuel Computer

Apexi SITC Super Ignition Timing Computer

Future mods: Hiflow RB25 turbocharger, Front DBA slotted rotors, Front braided brake lines, and lastly a Full suspension kit with most parts from the Group Buy

Cheers, Brendan (see SA section for details on my REAL beast, the Fireblade!)

AFM's are funny things sometimes, when for $200 (or less) more you can get a brand newie... thats what i would do personally.

Sometimes you can get great 2nd hand gear is you know where it comes from

Hmm... 140 still seems waay low for an RB25 AFM to max out at without a though. Interesting!

[Tangles]

Cheers mate, I thought newbies (Z32 afm's) were around $400? I couldnt find a 2ndhand one for less than $150US (on ebay, I know you dont like it!). Where are they for $200? Id buy one new for that price for sure!

Yeah, I was very surprised at the dyno report, AFM near maxed out, injectors at 76% duty cycle, good a/f map at 12.0:1, 141.3 AWKW.

So, Ive done the Z32 and doing the FPR / fuel pump / fuel lines to help out the injector flow (hopefully)..... getting it all ready anyways for the high flow turbo (got a 2ndhand one sitting at home, was meant to be a Neo but it isnt.... )

Looking for around 200awkw+ with the hiflow, eventually.

Brendan

[R31Nismoid]

$200 on top of what ya pay for a 2nd handie, sorry wasnt very clear

[Tangles]

Cheers..... yah, eventually, just on a 'tight' budget at this stage(a). (sorry, bad joke)

This time next year when the hiflow happens, might look into a new Z32 AFM, depends on how the current one is holding up.

Looking forward to picking up the Stagea from the shop tommorrow to see how the tune affects the car. Cant wait....
