which rb25? series 1 or 2 or neo?

won't work with series 2 or neo for sure

i vaguely remember that it'll work with r33 series 1 rb25.. not 100% sure, someone else might be able to shed some light on that

have you tried cleaning your afm and the plug connecters?

afms rarely break so you might wanna give that a go first, usually it's the oil from wet pod filters that go on the afm, or dirty afm causing car to not run properly

should be fine if you give it a clean

yeah im going to clean the afm tommoro when i change the plugs, will prob be dirty cos the old pod was very oily!

ill give it a shot,

also, would a dirty afm or dirty plugs cause the turbo not to hit its normal boost level? usually runs 12.5, but since this prob started, it barely hits 7 pound

what kind of problems are you having at the moment? misfiring?

anything that causes your engine to not run smoothly will effect your turbo from spooling properly..

might still reach full boost however, just won't get there the way it should

if there's problems with your afm your car's most likely to stall, or won't idle properly

rb20, rb25 s1 and rb25 s2 are the same phyiscal AFM

the difference is colour label and rb25 S2 has 1 less wire (shared ground).

to use rb20 or rb25 S1 in S2 you need to duplicate up the ground signal.

the rest is the same.

rb20 - 4 wire - ground, power, signal ground, signal

rb25 S1 - 4 wire - ground, power, signal ground, signal

rb25 S2 - 3 wire - ground, power, signal

check my site for pinouts etc

check howto section for a thread cubes did on wiring and changing them

rb20 - 4 wire - ground, power, signal ground, signal

rb25 S1 - 4 wire - ground, power, signal ground, signal

rb25 S2 - 3 wire - ground, power, signal

Thanks Paul for confirming, so ya the rb20 afm is plug and play on the rb25 s1..

ur car's s1 by the looks of it, so try on the rb20 afm and see how you go

    • The 296mm rotors are the R33 turbo brakes. The 310mm rotors are the R34 turbo brakes. The calipers are nearly the same, but not. They're the same caliper but the R34 caliper has longer legs so that it sits out far enough to go over the rotor. The pads are the same for both. When you say, "I bough tsome EBC"....did you just mean pads? Or rotors? 310mm rotors fit under 17" wheels. There may be some wheels without enough clearance though. I can't fit my fingers between the barrel of my wheel and the "corners" of my R34 calipers, but there is plenty of room behind the spokes. This is on Enkei RPF1. You can fit 324mm rotors inside a 17" wheel, but I'd be willing to bet that it would be close to impossible with the Nissan/Sumitomo caliper (using an adapter, of course), because the Sumitomo caliper is fatter than the Brembo caliper that is supposed to go on the 324mm rotors.
    • Hi. Can someone tell me what brakes(and mainly WHERE) can i buy brakes on R34 GTT? I bought some EBC which SHOULD go on my car(i have GT but it has GTT brakes) but it does not fit, Brakes are "too" small(296mm) Are 310mm be good or? I have 17 inch wheel so no "big boys" but for me driving i just need one that fits and i can get here in EU/Czech.
    • Since winter isn't that harsh anymore in Poland, i will definetely drive it 365 days a year 😉. But if the snow hits i will try it for sure and let U know. Only swap i am planning to do is of course R34 GTR front 😍.
    • Hey. Very valuable information about pitwork, I will pay attention when buying any consumable parts 🙏 As for the carpets - I got a handful of information from nengun, from which it appears that indeed the carpets for the driver's side are OEM. They are not able to show me any pictures due to the long chain of different sales entities but after I place the order, as soon as the goods arrive at the nengun warehouse from which they will send the shipment to me they can send me photos and if my purchase differs from OEM I can immediately return it / cancel the purchase. I think I will give it a try 😉. Of course i'll let you know what's what as soon as i get them P.s. I know the topic is not relevant to the thread, but both nengun and amayama have these SICK 😍 trunk room lamps available. Do you know anyone who ordered them? I need to have one in my car
