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 :)

WHAT THE HELL IS A 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, SteveL Thank you very much for your reply, you seem to be the only person on the net who has come up with a definitive answer for which I am grateful. The "Leak" was more by way of wet bubbles when the pedal was depressed hard by a buddy while trying to gey a decent pedal when bleeding the system having fitted the rebuilt BM50 back in the car, which now makes perfect sense. A bit of a shame having just rebuilt my BM50, I did not touch the proportioning valve side of things, the BM50 was leaking from the primary piston seal and fluid was running down the the Brake booster hence the need to rebuild, I had never noticed any fluid leaking from that hole previously it only started when I refitted it to the car. The brake lines in the photo are "Kunifer" which is a Copper/Nickel alloy brake pipe, but are only the ones I use to bench bleed Master cylinders, they are perfectly legal to use on vehicles here in the UK, however the lines on the car are PVF coated steel. Thanks again for clearing this up for me, a purchase of a new BMC appears to be on the cards, I have been looking at various options in case my BM50 was not repairable and have looked at the HFM BM57 which I understand is manufactured in Australia.  
    • Well the install is officially done. Filled with fluid and bled it today, but didn't get a chance to take it on a test drive. I'll throw some final pics of the lines and whatnot but you can definitely install a DMAX rack in an R33 with pretty minor mods. I think the only other thing I had to do that isn't documented here is grind a bit of the larger banjo fitting to get it to clear since the banjos are grouped much tighter on the DMAX rack. Also the dust boots from a R33 do not fit either fyi, so if you end up doing this install for whatever reason you'll need to grab those too. One caveat with buying the S15 dust boots however is that the clamps are too small to fit on the R33 inner tie rod since they're much thicker so keep the old clamps around. The boots also twist a bit when adjusting toe but it's not a big deal. No issues or leaks so far, steering feels good and it looks like there's a bit more lock now than I had before. Getting an alignment on Saturday so I'll see how it feels then but seems like it'll be good to go       
    • I don't get in here much anymore but I can help you with this.   The hole is a vent (air relief) for the brake proportioning valve, which is built into the master cylinder.    The bad news is that if brake fluid is leaking from that hole then it's getting past the proportioning valve seals.   The really bad news is that no spare parts are available for the proportioning valve either from Nissan or after market.     It's a bit of a PITA getting the proportioning valve out of the master cylinder body anyway but, fortunately, leaks from that area are rare in my experience. BTW, if those are copper (as such) brake lines you should get rid of them.    Bundy (steel) tube is a far better choice (and legal  in Australia - if that's where you are).
