i just purchased the Nismo intake, headers and exhaust and i was wondering what kind of gain i am looking at? any feedback would be appreciated. thanks

 

good choice on all of the above by the way!

Through all of my reading on here, it seems Nismo underrates the gain on its parts by a small degree to stay honest. You will very likey see the gains claimed on these parts.

I would guesstimate about a 10hp gain from 2500-6000 and you might see 10-13hp near redline. Im just guessing but you have to realize that bolt-on mods dont add up linearly.

 

u agree with around 10ish...
maybe a bit more...
get test pipes and u gain more from exhaust

 

yeah either high flow cats or test pipes would be really good. HFC will give a more mellow sound with less "rasp" which is that hollow coffee can sound when the throttle isnt 100%

 

I am doing some research for the best performance/quality HFC's to compliment my Nismo mods. A friend of mine at my local dealership has a good friend at Stillen where they test and dyno all sorts of mods. Right now they are testing 3 different Hi Flow Cats and which ever comes up with the best results will be the winner to be added as the next mod for my Z. Even though Nismo gains do not compare with FI, I am still very happy with my car's performance. After the Cats, the next mod for me will be the Nismo Cams (once I hit 7,500 miles).

 

Get some resonated test pipes!

 

Im running UTR stainless headers with my Nismo exhaust and my Crawford high flow cats compliment the note of the Nismo exhaust perfectly.

 

thanks for all the input. hopefully this will get installed this weekend.
