Oh great, these weren't there when I started posting, way to make me look stupid bud!

Edit: They're not the right size, I've just scaled a tech drawing of the VspecII and it's vent is ~180x120mm, those are too big.

Edit Edit: I've superimposed the R34 drawing over a R32 drawing. The R34's vent location is right in the middle of the rib on the R32's hood, so I moved it a little to the right. This is pretty much how I want it to be:

oh they were around for ages alright, carbonmodsuk had em stock since 2009...


I wasn't trying to make anyone feel stupid, just throwing something out there for anyone who needs these dimensions. I dunno why you felt my post was specific to you lol.

If you want to find something within the dimensions you require, use a simple search: http://www.google.com/search?q=naca+...&aq=f&oq=&aq=f

Also, wouldn't you want the duct to be slightly closer towards the firewall if you want to emulate how the BNR34 VspecII did it?


Cheers

Don't worry I was being sarcastic lol. Like I said, both tech drawings were super imposed so it's actually ballpark the same distance from the firewall as the R34. It's odd to see so clearly that it's actually not that far back, but it makes sense since it would put in above the TT pipe with the inlet flow freely extending to the firewall. Too close and it would be pointless turbulence.

Edit: Oh and seriously I had checked ebay before my first post in this thread but there weren't regular vents, only deep tube inlets for windows and etc.

Edit: Holy s*** $800 for R35 naca ducts, seriously?!

R35 TAX.

If someone made a mold out of the R34 vent, then replicated it in FRP or CF, he/she would make some good coins.


From what I read, the vent was for the rear turbine which have cooling issues compared to the front one.

[MarusGTR]

It sucks to be a purist! And yeah it was meant to cool the rear turbine.

Thanks to your link (how to you find that shopping tab?!) I did find this one http://roadracemotorsports.com/store...roducts_id=856 but it looks like doo-doo.

Now if Nelson would drop by for a peek I'd be real interested to do business...

froogle on google, then u can find about anything for a good price on there.

Awesome. I was trying to see if it's worth it to get NACA ducts on a BNR32. I still don't think they're as good as vented hoods that allow hot air to escape that's ok. I love the way NACA ducts look as a cosmetic mod.
