NA nfinished builds question
 

I have searched for NA builds and found a few is there a place where they are all listed with their numbers like in the FI finished build section?

Most likey not. Not many people go that route. If your building a motor most go FI on top of that.

What I meant was built motors but also just stock motors with intakes /exhaust ,tune etc giving all their info so we (noobs ) can get a better of what to expect out of just a stock car with bolt on's a a tune or uprev etc . perhaps we can come up with a best possible combo for power and tourq , sound vs style . handling which coilovers etc etc I would have to say my biggest disappointment with the Z is the lack of power tuning options and the cost involved .I was hoping to stay NA and get 350 hp -400 to the wheels with a tune . How much can you get without going FI? 310hp ? anyway just an idea.

Current top end NA power is around 330whp, that is intake/exhaust/hfc/pulleys/tune and I might be missing something.
There is a 350z that just hit 370whp, but that was heads/cams/ITB/exhaust/pulleys/tune and more, was on a 100% track ready car.

Now, can a 370z hit that same whp? Probably, but it will be a heavy investment of first run parts to one off parts to push the limit of your car.

Noobs, always ranting about how you want more POOOOOWWWEERRR! First I'll answer your question. If you want power while staying n/a get long tube headers, full exhaust, intakes and a tune, it'll net you 330-340whp.

With that said, those of us with extensive time behind the wheel of a Z know that power is half the Z's allure. The car is well balanced and unlike many other more powerful cars, it actually lets the driver put all the power down on the road while maintaining a comfortable level of control. If you want big power get a Mustang, I for one can't get past the looks and size of the new Mustangs.

As I love to say. Let me see what you can do on the track. Fast driver is better than a fast car.

Never said I wanted big power just wanted to be able to reach a modest goal with out spending a crazy amount of money to get it . I actually am not power focused . that being said I think the ceiling of power (staying NA ) that the Z has is disappointing. and the FI options are quite expensive . I also dont like the stangs either but if there was an option to have a VK56VD powered 370z I would get one and I am sure the Z would be more popular

Well, remember you are dealing with a V6 motor so NA is limited when compared to a V8, you are not going to get 450whp. I will say 400whp is probably doable in the 370z, but you are going to put up big money to achieve this. Now if you want modest goals, then intake/LTH/exhaust/pulleys/tune will probably give you what you want.

Throw in some balancing, coilovers/sways/weight adjustments and you will have a solid car.

^ Yea that's another thing. Stripping weight helps a lot too.

Yeah, my car is all out of whack.
Rear hatch is gutted, but added a SC to the front. :facepalm:

Maybe one day nissan will move the tranny to the rear type setup to balance this all out.

Well, I still need to move the battery and possibly migrate a few other things in the front which will help.

That's what I've been researching today. The battery is a big boy. My new seats made a huge improvement. When my new steering wheel gets here I'm going to bolt my seats to the bracing and get rid of the sliders.

Yeah, seats are probably a fairly large reduction and center of the car also which helps. Only issue for me is I need seats that lower me, being 6'5" is tough. :shakes head:

That's actually the main reason I'm doing this. When I mounted my Recaros tht actually sat higher. I hate that.

I'm NA. I have Stillen G3s, Berk HFCs and CBE. With the UpRev tune I'm getting right around 310 to the rear wheels.

OP if you want to wake up the Z while staying N/A get some gears. For what its worth, the Z is surprisingly fast in stock form. I'm waiting for the new Hyndai Genesis fans to argue that with the bump in horsepower its faster. The new Genesis is said to do 0-60 in the low 5 second range.

With the mods in my sig I'm now at 334 at the wheels.

ya but on what dyno

baselines help.... but hey, those are just details!

It was a Dynapack dyno at Xact Dyno here in Tempe, AZ. For reference, my buddy from work got his 2010 370Z with Stillen G3s, FI LTH and HKS exhaust tuned there on the same day and got 316 whp.

Also, I had my '09 370Z tuned there last year with Stillen G3s, Berk HFCs and Invidia exhaust which also yielded 316 whp.

not a fan of hub dyno's, doesn't take into account wheel weights.

prepare to spend a ton a $$$ to get big NA power !

My baseline on the same dyno SG used with their 350z was 256whp and I ended up to 324whp (330whp STD), He still have 48whp more than me !

with conventionnal mods CAI/tp/exhaust/pulley , they (370z 6mt) were about 310whp on that same dyno.

what I have more than those others 370z 6MT?

first my 7At which eat some power
2=bigger throttle body
3=bigger maf tube & CAI (custom)
4= step long tube header (PPE)

I had the HR intake manifold , im sure I would have gained a little more whp on the top end (intake runner length) with the OEM VHR intake manifold.

with some more tweaking on the intake part and possibly my exhaust , im positive to find another 5-10whp
but after that it will get expensive
I heard yesterday about a Japan company making an exhaust cam for the VHR !! :)
+ JWT are making an adjustable cam gear that is compatible with the VHR !!

Very interested to hear more about this..

yeah me too ,, if I had some experience in that kind of job ,, I would install them but Im gonna wait like everybody else , for someone to actualy do it.
Im curious if they changed the pistons because of valve clearance

What part of canada are you in. If your in the toronto area bring your car to TAG motor sports and dyno it. Mine with all bolt ons made 304 to 309 sae rwhp on his dynojet. ( 322 std rwhp).
You should bring your car to the drag strip and see what it runs.
You dynoed in 4th gear ?
Mine is also a 7 AT.

Z

Im near of Ottawa (CFB Petawawa).
yeah I asked you previously where you dynoed your Z before but I never received any PM reply about it ..
I would try your place but the weather wont probably be close to what it was when you went there , so a big change could be seen in the power.

the 321whp SAE dynojet at DaSilva was done on the 5th gear. with my 3.9 final drive .
I think you did yours with the 4.xx final gear ?
from the test I did on the dynojet is if the car has a higher gearing ratio it will show less power

on the 4th gear I got about 310 sae whp
on the 5th gear I got 321 sae whp

on the dynapack it was completly the opposite. 4th gear gave me 345 sae whp & 5th gear = 324 sae whp

Easiest mod ever: if you want more power step 1.) Get a baseline dyno on a MUSTANG dyno. Step 2.) get a second number on a DYNO JET or DYNAPACK dyno. \Either choice in the second option will show more power than the first!!11!1!1

But in all seriousness: intake/FULL exhaust/pulley/tune/lightweight flywheel/motordyne plenum (maybe) are about all you gonna get. --330whp. As far as i know, no one has done a built motor and stayed NA (there really is no reason to)

I'll pass on the pullies

:rofl2:

@ O&G, haha you know its true!

Couldn't have said it better myself! lol

yea i went from 285 to 334 and i dont think ill be able to do much better then that... mods in sig

I'm wanting to eventually do an N/A build, but you are looking at spending more money for less power on an all out N/A build than you would with just a mild TT setup.
