just wondering how much power rb20/25 afm's will support on a R32 gtr? I see most people use the z32 afm's but they are quite alot more expensive. Was reading an old zoom mag and they said to use the rb20/25 afm's. Im aiming for about 300 - 320awk. Will thse do the job? Also do the wires for the plugs need to be changed around or are they straight plug in?

Cheers

plugs are the same but the flex hose will fit if you try really hards LOL. you will need a re map thought as i did this to find it was very lean on the air fuel ratio.

Cheers mate. looking at that then 2 rb20/25 is plenty for what im after. You know if the plug or wirring needs to be modified to fit to a rb26?

Interesting people have not steered ytou on the straight line!!!

You'll be able to get away without changing the AFM's

Ferni did using GT-SS i believe, and im also gonna give it a whirl on my very similar setup :P

Munna's "rule of thumb" is totally wrong in its power readings.

Z32's/Q45's read a fark load more than 250/300rwkw respectively

Although its more about airflow than power anyway

well maybe i should keep the cash and go for the tune straight away with the standard afm's. im running hks 2530's pfc and have a set of sard 700cc injectors to through in. Think i should invest in a pump then instead of afm's.

Is it possible to put an external 044 inline with the standard pump without using a surge tank?

Hi, I have R32 GTR with standard afm's and 375 kw at the rears on 18psi. Havent tried to push them any further yet though. Hope this helps. :thumbsup:

Do you have a Power FC?

What is the max voltage you see, as i regularly see 5.1volts with 310hp(230kw?) at the wheels.

Anyone else maxing there AFM at similar power level?

So you say you standard 26 afm's a maxing out at only 230rwk? something cant be right there. They both read that?

Hi, yes I do have power FC. Im not sure about the volts, I dont realy play with my FC, But Ill try to find out for you next time I drive it.

Yeah mate I know, I"ve read the tables too,with 400hp atw apparently the limit on std AFM(or Scoop may prove us wrong)

But they both read roughly the same,using the sw check they seem to fluctuate within a few millivolts of each other.

Could also be due to the cold weather as I never noticed them sitting that high in the summer.

It would be interesting to see other peoples power and peak voltage..

Hi guy's, first up Im not a tuner and I dont claim to know much about tuning. Im trying to learn but its all beond me, give me a chev with a holly carb and I can tinker with that just fine. Anyway my AFM are maxed out [no tuneing resolution] but they still flow the air to support the power. That is the way it has been explained to me, and that is all I can go on. What power would I need to run 10.9 @ 127.4 mph? Fair bit of wheelspin through first gear. This was my first time out with the car as we'll. :(

You ran a 10.9? or your asking how much power you would need? What turbos are you running?

    • GTSboy, thank you again. i’ve been reading all the other SAU RB25 vacuum line threads and you have the utmost patience for people asking “where do my vacuum lines go”. it’s appreciated. i did also enlist a few other RB guys local to me.  i would like to run 5 to 4. turbo pressure side to wastegate actuator. i would like to run 3 to 1. power steering air valve line to intercooler outlet. (this is how it was previously). i was told 2 is the bleed port for the boost solenoid - which i’m not running - so should be capped.   anyone see any problems with that?    
    • So yes. All of them. Something like 98% of all fuel in the USA has 10% ethanol: https://afdc.energy.gov/fuels/ethanol-fuel-basics It's labelled as like, AKI, 87, 91, 93 with an E10 or E5 or E15 label on the pump. At a certain point, it's not just "E10" instead of 91. It is 91, 95, 98, and all of them have 10% Ethanol in them. You can also get E85 and E30 which is why you do see some people rolling around with E30 tunes in them.
    • Thanks for the response. This is an 04 EP3 Type R. JDM spec. Fairly certain they're just basic BC racing coils. I do plan to keep as the ride quality on stock I've been told is pretty meh given Sydney roads. If I were to go down that avenue, does NSW require them to be a certain spec (close to original) etc?
    • Should have asked what is the car?
    • I've had two super conflicting experiences with blue slips. My 30 year old E39 waltzed through with no issues but my brother in law was knocked back on 12 y/o 3 series due to wiper blades and some cracking in a control arm bush.  What kind of coil overs? Do you want to keep them after?  If it was me I'd get some dirt cheap shocks and springs from eBay or scumtree. Not ideal but will get you over the line and might even be less than $1k.
