nismo exhaust upgrades!!!!!!
 

whats up guys i have a nismo and i would like to know how test pipes would fit on my car being there no flanges? second hows the injen intake because i see that the stiLlen gen 3 does not fit my car because of the nismo bumper.

I would stick with high flow cats, just as good of gains almost.
Are you sure the stillen gen 3 will not fit? The Injen have shown some nice gains and a good upgrade.

test pipes over hfc's will net you a whopping 2 to 3 more hp...stick with hfc's...

Test pipes last like forever, hfc don't
test pipes have a few ponies more
test pipes are cheaper priced compared to hfc

so get the test pipes

He may just want to wait for long tube headers then.

im thinkin test pipes less restrictive plus i dont care about emissions lol the gen3 doesnt fit the nismo so im f*cked there im thinkin get the injen good company i trust there products but fellas will the test pipes or hfc's be a direct bolt on to the nismo exhaust?

Unfortunately you are one of the first/early Nismo owners doing upgrades so you might be doing the testing yourself. :(

Yea it's a direct bolt on and yes a bit less restrictive... A few more hp at most

I was under the impression that the Stillen Gen 3 would fit on the Nismo? If not that definitely blows.... If anyone knows someone who has tried it I'd like some more info.

The other upgrade I had in mind first was some Berks or other HFCs. No thanks for the test pipes, I live in a townhome, so the neighbors will thank me lol.

Long tube headers would be awesome :twocents:

Also, EVERY time I go for a fast accelleration pull getting on the highway or something I want a lightweight flywheel more.

I'm looking into either the Berk or F.I. HFC to go along with my Nismo exhaust as well. Probably December timeframe.

All the CAIs that fit on the regular 370 will fit on the nismo...not sure where this not fitting s**t is coming from - same with all the exhaust btw.

Agreed. I have no reason to swap out the factory cats for high-flow ones. Test-pipes are significantly cheaper, lighter, and will produce more power.

On the Stillen website, it clearly points out in the description of the G3 Intakes that it does not fit the Nismo 370z (same thing for the 350z intake and their nismo). Not sure if this is just a precaution to avoid figment problems or a proven fitment issue with the Nismos.

weak :(

I may call Stillen and ask about this specifically. It seems more of a precautionary thing, because looking at the bumper I can't see where the problem would be.

Would this mean that short ram intakes would fit though? Isn't that significant reduction in hp/torque compared to long tube intakes?

I wonder if there's been any word yet on the Nismo CAI.

I received this after inquiring about the Stillen G3 Intake fitment issue with the Nismo.

"There appears to be a diffuser plate that gets in the way."

The Stillen rep was uncertain whether or not this plate can be removed or modified to allow installation of the intake system.

/sigh

Ill find out this weekend as I already have the stillen here w/ the car.
Ill report back here or in a new thread.

Here goes nothing.

Woo gl :crossesfingers:

I've never been so excited. Gotta wait until the weekend? :(

Good luck man. Let us know!!!

Yep, there are some air flow plates in there that the non-nismo does not have. They can be removed,three rivets and a bolt per side. The Injen CAI does not interfer because it goes down into the bumper area in front of the wheel well. Attachment 6479

Attachment 6480

What's the purpose of the plates? Any cons of removing them?

Looking at the difference in gains/sound reviewed by other members, I'll only go with shorter intakes if the Stillen G3 simply will not work. Plus, not sure if it can be changed, but I like the color of the G3 filters!

Not 100% sure. Probably to keep the airflow a little bit more laminar. The nismo nose is longer and they don't want air curling around the front bumper support. It's not a big deal to remove, if you are putting the g3's on, and if it does cause a problem you can always rivet them back on. I pulled mine off to put on the nismo front brace. Had to cut a slot in them to make it fit and then riveted them right back on.

Well, it can be done, but I gotta go by harbor freight to buy some more tools.

Can't wait to hear more!

Great info. Makes me think I'll just go ahead and get the G3 and do what needs to be done. Maybe do the nismo braces at the same time :D
:pics:

I wonder if putting the Nismo ducts on a non Nismo car will help stock intakes get better air flow?

Well. HalfwY there. If I had another person to help or if I was more confident in my mechanical abilities I would be done by now. Have to wait a couple more weeks now. But It will fit as already stated by others

Sweet keep us inthe loop :tup:

Could you briefly describe any hiccups you've had along the way? What's causing the delay?

Good luck man!

Don't think they would fit. Probably would not need them on a non nismo as I think the bumper is closer to the core support. Not 100% sure. Nobody has let me take there 370z bumper apart yet. :icon18:

Hiccups are that there are a few differences on the nismo bumper than on the fang bumper and there isnt much info that is helpful. That and I am probably being overly cautious. Any how, we got the berk cats, stillen g3 and short shift done yesterday.

Here are some picks and I owe a lot of thanks (and some cash) to my brother in law who happens to have a lift which made doing these mods possible.


A few pics-

You can see the diffuser which I didnt have to do anything to, but is now a little out of alignment to make the g3 fit.

And a few pics of my baby on the lift.
The lift saved us HOURS and was MUCH safer than how I started on my own.

Overall nismo fans, I would highly recomend these mods. The car sounds incredible, feels noticibly torquier (and Im not past break-in so Im not pushing past 4k rpms YET:happydance:) and their are no CELS so far but only 200 miles on it so far. The short shift kit is awesome but a pita to file away for reverse and get just right. lots of filing for 15 seconds, put back together, test, take apart, repeat.

It was a great day and very rewarding but a lot of hard work, laughs, and cursing.

I love it.

Awesome job man. +1 for the info.

Nice choice of mods and glad the G3's fit for you and all Nismos for that matter :tup:

yay they fit! :happydance:

thanks for all the info man
