Um by the way...we still havn't established what the car actually already has???he may have half the stuff that paul 33 has listed so in that case...where could his extra money be better spent? a better turbo perhaps or maybe a bit more tlc to drivetrian or suspension in order to put this "250 - 300kw's" to the ground

He said the car is completely stock, so it will have none of it.

Did you read the first post?

I think it was clearly established what he does, and does not have

The car is completly stock and i'm wanting to use it on the road as well as one the track.

utilizing an air flow meter is going to offer a safer tune every time, and at those power levels the right type of afm isn't really going to lose you massive amounts of power, so personally i know what i would be using. check your facts and your "reliable source".

If GTR injectors aren't the straight drop in then what is?

so s15 injectors are? any others that are higher than 480cc?

You are better off going for some Nismo ones. Will cost about $900 all up and fit straight in. Cams will also be required for a safe 250rwkw and I would be budgeting $15k for the whole lot including labour

ahh guys, where is the love? i think some people are getting a bit hot under the collar.. let's examine the facts:

FACT 1: An afm is a better option for the kind of setup this guy is after

FACT 2: After a careful read of FSTR32, both he and his "reliable source" don't have a clue what they're talking about and FSTR32 refuses to admit this even though he/she has been presented with credible evidence to which he/she has replied to as being "WEAK"

so, the solution? FSTR32 either shuts up or pulls his/her head in and we can all go back to being happy forum users.

I would love to get nismo ones, but I can get them s15 injectors very cheap.

Well actually basically anything coming off a japanese car.

Just wanted to know my alternatives

nismo 550 or 740 injectors are straight swap, or you can go the sards which require an injector collar to fit.

I have the sard 850cc on mine, which is overkill until the engine is rebuilt and I can get the most out of the gt3540r

Just because an engine produces 369rwkw with an AFM doesnt mean the AFM isnt causing a restriction and that there is nothing wrong with the AFM as you say. Your logic is to look at the end result without a proper control (ie no AFM) which is nothing but inviable.

Honda and certain toyotas run MAP. Have you driven a vtec-powered car?

Youre always the first to say if its not needed than dont buy it. Well what about this case? The afm isnt needed and unless youre a track racer where a split second counts the AFM isnt needed at all. He can save himself money on not buying an AFM.

Better yet, you can even see the video and look at the nice telly screen of it. :)

How good is that eh? Stuff having a sheet, live video recording is a joy.

That also includes a backup run of 358rwkw with a bit less timing.

Safe to say there is nothing wrong with an AFM based car at all.

WHAT THE HELL IS A AFM??????????????????????????????????????????????????????????????????????????????????????????????????????????????????????????????????????

My tuner has expirience with both MAF and MAP applications for the RB's.

If he tells me in his expertise that the AFM is not a restriction, then i'll believe him based on his testing and applications.

I trusted his judgement and made more power than anyone else said was possible at the time.

When a PowerFC is $900, and the AFM $250-$300 thats $1200.

Would i be right in saying a MAP based ECU is a little more expensive in most cases?

The closest that comes to mind is $1400 at the very least. I think more decent are wire-in at a $2000+ cost

So cost for cost, the AFM + PowerFC Combo will works out cheaper.

As stated he is in Vic, and *most* tuners will prefer to use a PowerFC down here as opposed to anything else.

Well not actually because a decent ECU that utilises the MAP sensor will set you back around a minimum of $2000 installed. Then the tune on top. So he would, in fact, be outlaying more money for it. There is nothing wrong with an AFM, there is also nothing wrong with a MAP sensor. Both have their pros and both have their cons. You can make more HP from a MAP setup but his aim is only for 250-300rwkw so the Afm would do just fine.

airflow meter.

the cost of saving on an afm and gaining possibly 0 rwkw or even 2rwkw and dealing with the crapness of map sensor driven tune is not worth the $300 saved

Air Flow Meter (AFM)

If you look near your airbox, there is a sensor in the pipe going to the turbo with a wire/plug on it.

That is the AFM :)

AFM stands for Air Flow Meter. Which is technically incorrect in this case as the Nissan unit uses a hot wire setup which should be referred to as Mass Air Flow Meter or MAF meter.

    • Hi, i’m making a rb25det coil loom for Vag short coil. Can anybody tell me which Ecu signal wire belong to coil number 1 and 2,3,4,5,6? The connecting switch in above pic is 8 wire i think white is for +12v and black for earth.
    • Was there ever a model of the Stagea m35 that didnt have a badge on the grill? I thought I saw that somewhere, some aero edition or something? I cant find it again? davemoto
    • Its a 2002 vr-x four VQ25DET, silver. Coil overs, lowered, polished alloys and sport exhaust. Bit of a project, was sitting in a shed for a while but runs and drives great.
    • I wasn’t able to replicate the sound anymore. It was a one time sound so maybe it was just coincidence but it was like small pebbles being dropped in a coke can.   should I try cleaning the MAF? It could be it’s functioning but dirty? I don’t know.
    • Update 4: Hi all. The car drives again! Haven't driven for long, only to store it in the garage again, but the test drive was successful. The coolant and oil leaks seem to be fixed for now. Temps on the engine were also very good, while moving I never even saw 80C water during the approx. 30 minute drive. Ate up all the coolant in the reservoir though so will have to fill that even more when I go to the car next time. One thing that pisses me off is that the RPM gauge is still f**ked, I even resoldered the board twice and used copper paste on the silly screws that are used as connections. Next time I take it out I'll take apart the board and fit new components, I'll see if I can get a replacement IC for it.  I have an appointment set for 22nd of September for the engine tune to 370hp. Alignment also still needs to be done. My hope is that I can get all the legal stuff over with by the end of this season. Anyone of you have advice regarding intercoolers? Currently there is an APEXI core fitted, one of those weird hybrid ones, 600x270x76. I don't think it's bad but it's not new and now I still have the chance to change it now to legally include it in the paperwork. Only issue is that the only options that would arrive in time are a HKS Type R intercooler or generic Ebay spec intercoolers comparable to a JustJap one. Ideally I'd order a Plazmaman but it takes over a month to receive which would mean making the car legal has to wait until next season. Would love to hear some input on this. Same story for my injectors, the previous owner was a nunce and put ID 1050x on the engine. They work but are obviously not ideal at "normal" power levels. But I don't see a reason to change them unless the tuner says it's necessary. I read online before buying a different exhaust that the top secret style rear diffusers won't fit due to the size of the rear resonators. My buddy and I made it work by slightly "adjusting the shape" of the mounting bracket and making some spacers out of 3d print for the mounting bolts. Fits like a charm. Just putting this here in case someone has this problem. Even the hefty HKS Silent Hi Power rear can fits without hitting anything.
