Hi i've just been looking for a cold air intake kit for my r33 RB25DET as i want my car to sound really loud and nice when taking off. I've heard some pretty nice r33's when they take off, some sound like jets taking off and i was wondering if this kit would give me that sound?

Has anyone actually got this kit on their car and knows what it sounds like and if it gives good performance as well?

Is the difference noticable compared to just an apexi POD?

I think this one is for a 70mm AFM so does that mean it'll just bolt on to a stock AFM?

The stock AFM is 80mm Dia. for an R33 same as the Z32 AFM

I think the steel intake would give a better induction note, but thats not the main reason for using one, they are used so that the stock rubber intake pipe doesnt suck itself closed when running high boost or a larger turbo.

are you sure the z32 is the same dia as stock r33????????????????????

rb26 76mm

rb20 80mm

rb25 80mm

vg30 z32 80mm

vh41 q45 90mm

so if the z32 has the same diamiter tube(and im not saying it doesnt as i honestly dont know i was under the impression it was larger so would allow more airfow for the same voltage output) but still reads up to 5 volts same as stock r33gtst how does it allow more airfow for the same voltage output??... i hope i made sence as having them the same size doesnt make sence to me

it has different calibration to the rb20 and rb25 afms

so at 4.1v its flowing more air than an rb25 unit at 4.1volts

i think its around 1.5v offset ie an rb25 at 4.0v its about 3.0v on a z32

      R33 GTR running -9 with no tune

      By joshuaho96 · Posted

      Yeah I suspect even if you hold airmass per cycle/cylinder constant if you get too far away from stock you're still going to have problems running the factory tune within the bounds of the factory load scale. Cams, different displacement/rod ratio, etc. I'm just lucky that the GTIII-SS with wastegate boost + CA compliance cats is pretty much equivalent to stock turbos. When I have actual space I can finally get it tuned and modify the fuel system for flex fuel to 100% handle any detonation concerns when cranking the boost to whatever those dinky turbos can put out.

      I would say no, why, because my daughter, who also lives in Goulburn, hasn't recommended us going there Pity, as we miss all the German joints around in Sydney, actually, the restaurants are the only thing I really miss about Sydney, and a special mention to Ishibanboshi at Bondi Junction, their Kara-age Don is heart cloggingly deliciousness (always added a special boiled egg...or 2) 😋

      Does that German restaurant still exist in the old place out the NW end of Goulburn? When I say "out the NW end of"...I am really being vague. It was 1997 when I was last there, and the only point of reference I can recall is that it was on the opposite side of the main drag from the big merino. And when I say "opposite side of the main drag", I don't mean "on the main drag". It was either a couple of streets back from there, or might have even been out in the sticks a bit further. Was an old farm building or mill or somesuch. And when I say "the big merino" I might actually be thinking of a completely different part of town, because I just looked on maps and the big bugger is not where I remembered him to be! The food was good, consisting largely of various German mystery-meat sausage/loaf things and kartofflen.

      So while the second sentence is completely correct and the whole point of the conversation, the first sentence bears consideration. If this bloke is just hoping to throw big turbos on and drive it around, because there are no helpful facilities at all in his tropical paradise** then he likely has zero chance of even knowing what the TP is on the last column in the stock maps, let alone know whether the ECU is operating anywhere near it or past it. So the point is very very moot. And, per what I said before, at stock boost on those turbos, you may well be off the end of the map. **I'm just back from Vanuatu, so I know exactly what small Pacific nations can be like wrt paradise without requisite facilities. But it's not even that simple. I put a high flow on my car and had to drive it around without a proper tune because of the lack of opportunity*** to put the bigger AFM and injectors into it to allow it to be tuned. I had to turn the boost down to less than I had before, and back off the boost controller's ramp, because it was exploring parts of the map that it didn't drive in before, and really couldn't access for tuning on the dyno either, and so was pinging. It was still well within the last column, because when I first**** set up the Nistune on the Neo I rescaled all axes of the maps to give some more space to explore. ***Family dyno was broken ****This was 13 years ago, and the TIM thing wasn't a thing then and so TP would definitely grow when pushing past the stock tune's limits.

      Squeaking clutch/throw out bearing

      By joshuaho96 · Posted

      Yep, this bit another local owner. I caught it before putting the transmission back into the car, what I noticed was the pressure plate fingers weren't flat and even. It's more obvious with the pull style clutch because the throwout bearing ring was visibly not flat once everything is put together. Nismo should really update their instructions to call out this specific detail. I'm not even sure the clutch as-shipped orients everything properly.
