See the below pic, anyone have these on their GTR - the bit from the front lower lip to the wheel well...

Are they are factory part, or are they a Nismo part??

I don't have em, and want a pair :D

Please enlighten me

I figured that you could duct them to the brakes...

cheerio :D

I was actually looking at not having such a dramatic change in cross sectional area along the length of th educts...as i thought doing so may cause turbulence at the inlet and hurt flow...albeit it would increase the velocity of air...

No doubt Nissan no more then me. :) But looking at race cars, after having a large throat to capture air, they typically maintain a similar cross sectional area, even if they do go freom rectangular passage to 80mm flex duct.

My undertray also goes to just in front of the steering rack...if you want one should be a bolt on between GTST and GTR once i am sure the ducting works (LOL, bring on Sandown)

I have them on my GTR....well i have one now! The other one ripped off as i had to drive somewhere without a front bar (cooler hose blew off and i was already 1hr late). I dont think the cable ties held it well enough. I was thinking of going proper ducting like V8 supercar style instead of using these. Otherwise i gotta find one more!

My 89 has them.  Looking at FAST suggests they are standard part for JDM spec R32 GTR's

I should add that my car also has a curved rubber 'defelector' attached to each of the tension (castor) rods, which directs air from the ducts onto the back face of the brake disc through a hole in the backing plate. These also appear to be a standard JDM R32 GTR part.

I doubt that it's particularly effective, but better than nothing.

i think the intention here was to have them double as pie coolers. pie too hot? place in front of duct, drive for 2 minutes then remove. perfecto. the reduced cross sectional area stops said pie from entering brake rotor - messy.

My R32 V-Spec II has them, but I have only kept to the tow point of the factory part, cut the rest off, installed a PCV downpipe section to convert the 4"x1.5" duct into a round 3.5" duct and run heat tollerent flexi ducting back to the rotor centre.

The item on my car that isn't in that pic is an extra air guide on the castor rods... again, cut and shut the air guide and its now just a bracket that the ducting is braced to.

    • Pfft. As if I'd ever point a high pressure washer at my car.
    • The nature of my commute has changed. Way back then it was traffic lights all the way, for ~28km. It sucked. When they finally stitched the expressway together I could do a good 15+km of it at a steady 80-100 with no stopping. That alone has gotten me down to flat 10s. Prior to that it was mid-high 10s. I can't remember the delta that I saw when I got the idle down. It was only ~150 rpm, because the idle speed was never terrible, but for the delta in consumption to be noticeable it would have had to have been at least 0.2-0.3 L/100km - which is not to be sneezed at when it comes for absolute free. It's only about 50L per year, but that's ~$100. A few extra pizzas is always welcome. Note that I have a record of every tank of fuel that has ever gone through my car except for a handful put in by someone else, like my mechanic. I can show you the difference between stock RB20 and tuned RB20, stock RB5Neo and tuned, winter and summer fuel blends, winter and summer fuel blends when the ambient temperature is not appropriate for the blend, working O2 sensor, blown O2 sensor, boosting f**k out of it and frightened to boost it because it is pinging, and so on. OK, I probably can't do all that now with 100% clarity - but at the time when any of those things were in event, you could see it in the records. There's 25+ years of simple tank after tank records, so you have to look for landmarks to work out approximately how old any single record is. What's really important is the meta data and that lives in my head.
    • If you're claiming the issues are not skyline specific, then either the USA is living in the 90s / early 2000s, OR you have the issue of "survivor bias". Which is you're mainly hearing and listening to those with terrible experiences, and haven't found the guys who have cars with good decent builds and no problems. It happens in AU too, that plenty of people keep having issues, and they keep going to the workshops that are known to be shit "because I read on the internet". Even worse, are those who keep posting on the internet as though they know for a fact what something is, when they've never touched/looked at said item in their life, and again are making assumptions, based on something they read, or because it's a certain way in other cars. It's even funnier when those same people debate the facts with the people who've lived and breathed this stuff for over 15 years. Example, I've had someone tell me you can't do something with a Skyline, because they read it on the internet, except I can tell they're wrong, as I did that exact thing back in 2008 with my Skyline.
    • The funniest part I saw, was someone would bitch and moan on FB about something, Andy would be the one to respond, asking for more info, if he could contact them, what the engine setup is, what their config file was, and 95% of the responses were people just going "der! It doesn't work" and Andy going "What doesn't work?" And then going "The firmware!" And they'd go around in circles as no one could ever give information, and Haltech couldn't fault things on the bench, (especially when people wouldn't give any specifics).   Many moons ago, when Andy was back at e420c stage, he reached out to me, and asked me to test different plug and play looms for him (already had an e420c in the car on his V1 PNP loom). And he kept asking me, as I was competent enough to be able to give him some specific feedback on what was/wasn't working, how to replicate the faults etc, and work through things with him. Most people are terrible at answering the questions they're asked, or being able to provide quality feedback other than "it doesn't work".
    • I say it often, none of this stuff is really Skyline-specific per se. But in general there's not a lot of people who actually know what they're doing. A lot of people charging like they do. Agile software development probably isn't the greatest idea for an engine controller.
