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.

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

      This looks great! Awesome to have the 5 speed with an LSD in this. The Recaro's look like SR2's or SR3's. It's a shame they've been retrimmed as they would have looked sweet in their original colours. I think I'd want my agent to be a little more up front and informative too. I've never imported but I reckon it would make me a little nervous, so the more info the better.

      Thanks for doing that Duncan! Makes you a good person in my books. We don't get kangaroos or wombats here. But we have bats and it's similar. AFAIK it's often the mums with a baby attached that get hit because they drop lower when starting from a tree. If you hit an animal, check on it. https://www.ifaw.org/au/resources/wildlife-rescue-app An app to get the closest wildlife rescue contact.

      Jacks that fit under GTR lips that can reach the subframe?

      My dream is also to have a proper hoist, but I don't think it will ever happen. My quickjack is probably as close as I'll ever get, it really is very good though.

      Yeah we keep on in the dailies, it is pretty poor how many animals get hit and the driver leaves without checking....have saved a couple of little ones over the years. Bit of a gruesome job though, pouches generally need to be cut open because they are so tight and often the joey doesn't realise mum is gone so they are still locked onto the teat. I checked the modules in front of the DS wheel where an oil cooler should go.... There is the radar unit - that can go for race use) One of the 2 HX water pumps, the silver cylinder. That needs to be kept but might be able to be relocated But the bad news, the big computer mounted vertically in front of the wheel (blocking any potential air exit) is the electric steering computer. That is required until/unless i do a hydraulic steering conversion, and in CAD based modern car design it is not like I can just pop a big unit like that somewhere else (plus the loom would be too short anywhere else too). So, the passenger side is OK to clear out (just use a smaller washer reservoir, potentially elsewhere), but the DS no beuno

      Well, all the best with the new camry It was interesting to hear about the UK process, it is generally a lot more streamlined here with a shipping agent looking after all the import side (noting the exact final price can still be a surprise.....) and I've used a few different brokers on the japan (or US) side, and never had any trouble with any of them....luck of the draw I guess. You mentioned you didn't get the auction sheet (understandable since you bought it from a dealer, not auction), but I always try and get hold of that because they are pretty thorough. I've imported 2x R grade vehicles over the years and both were fine, repairs in Japan are pretty thorough compared to here in Oz.
