Hello all,

Ive spent the last month or so lurking this forum and other 350z forums just so I can (hopefully) write somewhat educated posts. My z is a 2007 Touring Coupe and i abs. love the handling and horsepower. That being said, please critique the following. I want to make sure I have my facts straight thus far

1. Since my Z is an 07, i dont need the plenum spacer nor the MREV2 manifold, being that nissan fixed this in the 2007 and 2008 models.
2. a)Yes, the better intakes like Injen or Stillen Gen 3 will offer more HP gains then the K&N Filters and....
b)Yes, the Borla/Injen exhausts will offer more HP gains then nothing. But....
c)We are still talking at most 20-40 more HP and will cost less then $2000. The only way to seriously add more HP to the 2007 350z (Naturally Aspirated) is to supercharge it. Thats serious money and serious HP, everything else for the NA is just bolt on and will give you positive yet limited results
3. Being new to cars, it would not be a smart or cheap idea to go FI on my daily driver z.
4. You can tell my Z is a 2007-2008 just by looking at the tach. The redline is at 7.5K
5. Stealerships are LOL
6. Assuming you drive normally, the OEM tires will only last about 20,000 miles. Thats how long my OEM ones lasted (i bought the car 18K miles in). My Eagle GTs (WHICH ARE AMAZING) have a wtty to 50,000, but im not sure thats going to happen.
7. 350zmotoring and 350-tech are solid additional sites to go to when doing research.
8. Ok im unsure about this. My roommate just told me that he thought all 2007 350z's were twin turbo'd and turbo kits wouldnt be needed. Truth?
9. Having 225/245 staggered tires is fun (my setup). Having 245/275s means work to your stock suspension. Also means baller.
10. I have a dual air intake. That means i need 2x as many parts. Oh well, more performance.


So, thats what i learned in the past month. I really want to mod, which is why i limited myself to no posts and no purchases. Just read, read, and when u think u know it, read some more. I almost bought that plenum mod the first week thinking i was good . Being that cost is always an issue, there are 3 general paths that I can mod down.

1. Moar HP!!!! Damn the curves, full speed ahead. CAIs, not that popcharger crap. Real dual exhausts. Turbos, S/C, and really mean racing stripes.
2. Real Zs have curves These types just want to make their car all pretty, inside and out. Purely cosmetic.
3. All your turns are belong to me. I think i am in this group here. Basically, dont care about HP or pretty lights, just increased handling, agility, comfort, suspension. Prove that muscle cars can beat you in the turns.

Now ideally we all want all of the above. So assuming Im concentrating for now in group #3, I'm looking at the below mods. Together, and maybe a little individually, the daily driver will notice an appreciable difference over stock and be glad for the time and money spent.

1. K&N Filter. Easy and cheap and from group #1, but better over stock filters
2. New Tires. These eagle GTs have so much more grip, acceleration, comfort over stock its laughable.
3. Hotchkis sway bars. Keep it to under 80% on the front, and the lightest on the back (staggered setup on tires) and people notice an appreciable difference in turns.
4. Short shifter. Stock shift is already short, but making it top heavy will lead to smoother/quicker shifts.

OK, wow thats it. Thanks to all those that read through this and the awesome threads Ive gone through.

 

8. Ok im unsure about this. My roommate just told me that he thought all 2007 350z's were twin turbo'd and turbo kits wouldnt be needed. Truth?

completely false.

 

Welcome and congratulations. Hey I live in the United States also.

 

I could be wrong but I believe the '07 does NOT benefit from a spacer. I'm not even sure there IS a spacer for an '07 Yes to the sways, as far as the settings that is up to you - play around with them. I used to have my fronts set to stiff - recently went to medium and it turns in so much better. Backs are set to stiff though. 245/18 up front, 275/18 rear. I don't have baller money so I go with less expensive tires than Eagles. Short shifter - I don't get that. some have made that mod and then gone back to stock. don't recall reading all that many great things about them.

 

Fixt mod #4 for ya

Just got my 07 a few months ago and that's the first and only mod I've done so far.

Ten bucks for an RDX antenna and it looks so much better.

 

Are you serious? Rev up motors are on 06 6mt's. 07-08 are HR motors and don't need plenum spacers. Please don't give advice if you have no idea what you're talking about

 

spoken like a champ!!!

 

Why thank you soon to be Long Islander haha

 

haha yessss i like it!!

 

Excellent gents, thank you for the confirmations. So people have found that the swaybars are better then stock, but the short shifter is only so-so? Ill do a bit more reading

 

I didn't actually read your whole post the first time so I'll go through it now and make some points about things your brought up:
-You talk about gains with different intakes/exhausts. Generally they will all yield the same results. Certainly nothing you'd feel so get what you think sounds/looks best
-Once you supercharge a car it is no longer NA. I'm assuming you realize that but I was confused by the wording of your sentence.
-Your roommate is a dildohead
-To run 245/275 you aren't really baller lol. I run that and its pretty normal to see (not stretched or fat). You will definitely feel better traction with wider than stock tires though.
-Yes you have dual intakes. You do have to add twice the intakes, but you have to remember you don't have to invest in a spacer which will negate that extra cost at least.
-Hotchkis sway bars are a good choice
-A few people have added a short shifter, not liked it and removed it.

Hopefully this helps you out a little and clears some stuff up

 

Is it just me, or did it actually hurt anyone else to read through that? From what I care to recall...your car isn't twin turbo'd, I seriously hope you're kidding about your "mean racing stripes", and no mod = "baller."

Ditch the short throw shifter idea for now and get a full intake kit. Tires and sways should be ok.

 

if you plan on tracking the car...ikeya formula squential shifter....

 

Yes, the racing stripes was sarcasm, but they do look nice.

I dont plan on tracking the car all that much, but I do like going fast on turns that are near I live. What benefits does that ikeya formula shifter have?

edit: holy crap those are like $2000. Def not needed for this daily driver

 

Funny that he edited his post to remove that bit of information.

Like NissanZ03 stated, with intake and exhaust, you're not going to notice much of a difference. I think your 20-40hp number is far off. No need to go true dual exhaust unless you plan on going FI. Best bang for your buck would be test pipes. Your roommate is an idiot. There's no such thing as a factory turbo'd 350Z or 370Z for that matter.

And no, racing stripes don't look "nice"

What is up with the education system? Proper English and grammar is a lost art.

 

I just sold my 2nd car for about $4500, so im not opposed to spending some money. But i want to make sure i get my moneys worth. The TWM Shortshifter looks nice, but its $300, but the stock is short already so I might not bother.

As for the test pipes, im reading that they and HFCs are illegal for non-track use. Would seem to be a waste of money when the only track (summit) is 90 min away

 

 

 

hahaha well my state funded education has failed me. let the lashings commence.

 

you silly goose
