How long is the flat part in the middle? 11" doesn't sound quite right. Most of the ducts I saw were in the 8-9" range if my memory is correct. It may make hose routing a little interesting, but I would think it would work.

Idk I am trying to figure this out before my bumper gets here by the end of this week. Maybe someone with an amuse kit can chime in and measure it for me

Well I purchased the NACA ducts should be here today and will attempt to make this work!

I decided to go with the revotec 4" (102mm) circular air inlets connecting to the Stillen brake cooling kit (like the yellow Nismo pictured in a previous post). The inlets were about $50 and the Stillen kit is approx $235. I'll let you know how it goes as well.

First of all, OP- Great job! I really like what you've done here! We were looking to see what we could do for the Nismos but we do have a lot of customers tell us that they don't want to cut ANYTHING on their car, so we didn't want to have to cut into the undertrays either. With that being said, this is for sure what I would do if I had a Nismo.

This is actually how our kit attaches for the factory fascias. We offer two options, one for the factory fascia (picking up air right where you point to) and the second option is for STILLEN fascias that pick up air from the modular/optional brake cooling ducts. This option can also be used for Nismo's and other fascias.

what do you have the hose attached to at the brake? Is there a bracket you installed? Do you have any pics of that?

ah ok, very nice. Was that purchased from somewhere or did you fab it? If purchased, where at?

Here's mine. :D

Looks like the stillen backing plates.

Wish i could buy just them...

Rusty, is yours the same kit/parts as the OP?

That's the stillen kit. Idk u can always ask them if u can buy just that!

Yea, that's the Stillen kit. ;)

Stillen was a real pain about selling just that portion of the kit to me, but finally did once I got to the right person

Installed my Nismo RC ducts last Friday and will be running the hoses from the ducts to the brakes this weekend. I'm inserting a piece of screen (Lowes hardware dept) between the duct outlet and the 4" to 2" reducer to keep debris away from the rotor.

Pics?

I also used the stillen backing plates to moun the hoes onto at the wheel end.

who'd you talk to over there? i want just the backing plates as well

Just drill a 3" hole on the dust shield: http://www.summitracing.com/parts/aa...2160/overview/

it's all you need and a few rivets!!

Tread back from old'.

@Chops: Kyle sorted everything out for me.

@Martin: We don't really have dust shields from the factory to do that.

Very cool thread... I'll be doing this next year.

The way the OP has his air inlets located. Wonder how much air is getting to the rotors?

Good to know there's a second option out there for nismo owners. Especially if they are boosted too. Just now seeing this after knowing about Rusty's DIY for some time. Has anyone besides the OP done this yet? I'd reach out to him for how it's been working but hasn't been active in 2 years. Wondering how the airflow is as well.

Sorry for the bump..
