Nismo Intake Air Ducts

[funnyman850]

Anyone have any insight on air routing for the intake son the Nismo? Wondering if it would benefit from some sort of ram Air intake. Ducting or a cutout.

It's fairly inconsequential as the car uses intercoolers to cool the charge air. While cooler air is always better, it's just the compression from the turbos is going to superheat it anyway and the intercoolers will bring it back down. Engineering some sort of a solution prior to the air being compressed in the turbo is going to have marginal effects.

yup that is the correct answer its not the same effect as like the ram air on a WSR trans am back in the day.


with that said HKS made something for stock air boxes. its more for car show bling

And with a turbo car, as long as you have good flow and relatively little restriction the turbos are going to suck in all the air they need. Just tooling along your turbos are still spinning and sucking even not under boost. If you’re cruising and pedaling the gas to maintain speed you’re almost running at 0 psi (little to no vacuum). If a ram air or larger fresh air ducting makes any difference it wouldn’t make remotely enough difference to tell.

My eyeball test is telling me these are at least +10hp.

That's not entirely true, cooler air into the turbos means cooler air out. I do agree that because the magnitude is smaller than the heat differential the turbos already produce it's not AS consequential as on a NA car but it still matters.,

For example, a 30 degrees temp differential between a CAI versus a HAI you might have 30 degrees cooler temps at turbo exit, but only 20 degrees after the intercoolers (because the intercoolers are more effective the higher the differential), but 20 degrees cooler is 20 degrees and I'd rather have 100 degree after intercooler temps than 120, even though the % difference is only a 17% decrease and not 30%(for 70° vs 100°) like an NA car would see with CAI

Good conversation.

I was planning on opting for the ams cai vs their 80mm intake for lower intake temps.

are we saying their 80mm intake will be nearly as good with the insert and better without insert?

to me the stock and aftermarket cold air intakes seem like they would be marginal with the small inlet opening and the sub par location..

I wonder how long it's going to take until someone cuts holes in the bumpers like the 350z aftermarket community.

Or the hood + K&N. lol

Anyone can and should do anything they want to their property......so no judging....

But I gasped at "Dremel + front bumper"

a guy in japan swapped the GTR DRLs into his Z NISMO turned out good for a custom cut up job

Boosted6 makes these: B6A Nissan Z Ram Air Intake Conversion – Boosted 6 Autowerks

I haven't seen anyone on this forum try them yet though.

That looks pretty dang cool. I'm sure my shock is more knowing my own lack of skills at such things and thinking about the mess I'd make of it. I can wrench pretty good but I cannot engineer to save my life.
