i see people running the afm in there intercooler piping and it works fine, but can i do this with my rb26? since it has two mafs? can i just put one infront of the other? will that work. im converting to single turbo so i would have to get the greddy y-pipe to adapt the two to one feed to the turbo. so is there away to run both mafs inline or am i stuck using the greddy y-pipe or stand alone to remove the mafs all together? is there away to run one maf? thanks

No, if you put them one in front of the other, they will each reas all the air, instead of half. If you want to modify onoe and put the internals into a 90,, pipe after the intercooler, them all you have to do is bridge the output of the afm and reprogram the ecu to suit.

You have to run twin AFM'S (MAF), cant run 1 because the ECU wont know wtf is going on.

Just get the Y-pipe to save issues, alternatively upgrade to a ECU that runs a MAP sensor (MICROTECH, WOLF etc..), that will enable you to get rid of the AFM's.

You cant run them in line, I reckon it will run like shit.

Whats the issue wth the Y-pipe? Price $?

Edited by abu

you should be able to run 1 AFM shouldnt you if you splice the wires together so the same signal goes down both line, or will that tell the ecu that there is twice the amount of air than there actualy is?

Just thought about this, say you have X amount of air coming into the car. The AFM is the standard position infront of each turbo will see 1/2X each. The computer then adds these together to see X. Now if you were to put one AFM in the cooler pipe (as there is only one pipe) it will see X amount of air. So running the 2 wires to the single afm would see double the air flow. I recon thats correct?

    • Yeah i found that alot of parts can be wrong or "very" hard to get the real right one. I already bought some brakes years ago on me "old" GT calipers and they were wrong too 😄  I told them too. Even send them pictures...but they said "EBC catalogue has them on my car... So i dont know what their answer will be. I call monday them and let them know that they are really not on my car. If they were they would be already on a car...
    • Welcome to Skyline ownership. Yes, it is entirely possible parts websites get things wrong. There's a whole world of inaccuracies out there when it comes to R34 stuff (and probably 33 and 32). Lots of things that are 'just bolt on, entirely interchangable' aren't. Even between S1 and S2 R34's. Yes they have a GTT item supposedly being 296mm. This is incorrect. I would call whoever you got them from and return them and let them know the GTT actually uses 310mm rotors. Depending on where you got them from your experience and success will obviously vary.
    • Hi...a bit a "development" on the brakes. I spoke to the guys where i get brakes from...and they are saying that 296mm EBC are for R34 GT-T. I then went to their site: https://www.ebcbrakes.com/vehicle/uk-row/NISSAN/Skyline (R34)/ and search for my car(R34 GT 1998 - it has GTT brakes) and it show me this USR1229 number and they are rly 296mm rotors... So now iam rly confused... The rotors i have now on the car are 310mm asi shown... So where is the problem? Does the whole EBC got it wrong or my calipers are just...idk know what?  
    • Oh What the hell, I used to get a "are you sure you want to reply, this thread is XX months old" message. Maybe a software update remove that. My bad.
    • This is a recipe for disaster* Note: Disaster is relative. The thing that often gets lost in threads like this is what is considered acceptable poke and compromise between what one person considers 'good' looks and what someone else does. The quoted specs would sit absurdly outside the guards with the spacers mentioned and need  REALLY thin tyres and a LOT of camber AND rolling the guards to fit. Some people love this. Some people consider this a ruined car. One thing is for certain though, rolling the guards is pretty much mandatory for any 'good' fitment (of either variety). It is often the difference between any fitment remotely close to the guards. "Not to mention the rears were like a mm from hitting the coilovers." I have a question though - This spec is VERY close to what I was planning to buy relative to the inboard suspension - I have an offset measuring tool on the way to confirm it. When you say "like a mm" do you mean literally 1mm? Or 2mm? Cause that's enough clearance for me in the rear :p I actually found the more limiting factor ISNT the coilover but the actual suspension arms. Did you take a look at how close those were?
