First of all, this site is huge. I hope I'm posting in the right area, if not I'm sure I'll hear about it, bear with me till I get more familiar.


So, I have a old history of autox, back in the day we called it Solo1/Solo2. Raced a MGB, Audi and later a Formula 4 Walker. Thought I had it out of my system but the kids are gone and apparently I still have the problem!
Anyway, I started looking for a car to autox (grey beard and all) I had a 06 G35mt and loved it, but a Z always turned my head, so that's the direction I went. I know with classifications it's not the best choice, but who cares, this time I'm racing casually for fun.


Then I found, fell in love with and bought a 06 350Z Grand Touring (showroom condition, not a mark and never seen rain etc. 21,000 miles) for a great - great price, last week. It's a A/T so again, not the best choice for autox, but I couldn't walk away from it. I might autox it once or twice to better learn the car, but honesty, it's just too damn nice to drive the s##t out of. So, that's where I'm at. (rather long intro)


My question is equally long...you guys seem to have the knowledge base of a thousand mechanics/tuners and I value your opinion.
The previous owner did some dealer installed modifications, which I will list (all Nismo). What I would like some opinions on is, do I leave it as is or should I get a tune to exploit the modifications done? (I have searched individual items on this site, but am having some difficulty putting the whole package together).


Here's the list...
-Nismo full suspension
-Nismo sway bars
-Nismo cold air intake
-Nismo headers
-Nismo cat back exhaust
-Nismo 19" alloys with 275/35 zr19 rear and 245/35zr19 front and the big, bold, gold - spotless Brembo's (with Wheel spacers)
-Nismo lower temperature thermostat.


**two things I'm going to do to finish it - grounding kit, motodyne 5/16 spacer.


Again, your opinion on the air/fuel tuning is what I'm questioning?? and I wanted to do some bragging haha - I'll put some pics up when I get a nicer day (Nismo rims are amazing and not a mark)


Thanks for hearing me out.

Hell sounds like the previous owner did it all, put a spacer on, maybe a diff and tune it and that is about all you can do. My buddy autox an auto and for a while he was one of the quickest.

 

Post pics!!

 

Ya funny he did it, old guy that never drove it (21,000 miles)
I don't plan or autoxing more then once or twice.


What diff mod are you referring to?

 

Soon, it's rained everyday since I bought it

 

Swap with a quaife, the stock vlsd sucks

 

Would you mind posting a vid of it running and a few revs? haha
I've been considering the Nismo R-Tune headers, but I can't find a decent reference for how they sound with the exhaust.

 

I can, but i'll tell you first - they're pretty smooth, not much difference over stock exhaust until you get up over 4k rpms and even then they're fairly tame. As far as hp gains ??

 

Sorry man just seen this again and i forgot, dont really have a camera that would do a good job of it.

One thing i would suggest is see if you can fab a heat shield up and wrap before install
