Tuning & Modifications
 

Hey everyone,

Well short story is I spun out my 2011 5.0 and it was declared a total loss vehicle so I took it as a opportunity to jump into a new 370Z. Loved these cars for some time now and I'm very excited about my new wheels. I have just one main question that I would appreciate help with.

How would one go about tuning these cars (parameters such as fuel, air and timing) once modifications are installed. For example with my 5.0 I installed a intake manifold, throttle body, cold air, long tube headers, high flow cats, performance mufflers and rear end gears. Once all this was installed all I had to do was plug in a SCT tuner to the ODBII port and load a custom email tune that was sent to me from my tuner and I was good to go

Is this similar for the 370's, are there tuners out there that send a tune based on your mods and you just plug a flash device into the port and load the new tables? If so what is the flash tool most commonly used?

I need some clarification on this as soon as possible please. I would also appreciate any recommended tuners and or suppliers for aftermarket parts. I also dont care if people feel that certain mods dont need tuning. I'm very picky and will tune no matter what mods are installed. Any help is greatly appreciated. I want to start my build ASAP but need some direction first.

Thanks

Here's a good start. It's probably where you should have posted this in the first place. Search is your friend, too :tup:

Tuning - Nissan 370Z Forum

woah, someone coming from mustang to 370Z! :eek:


like a saltwater salmon swimming up a river.

take it to an uprev tuner and have them dial it in perfectly

Well, first of all welcome to the forum. Second, there is a lot of info regarding tuning on here to help get you up to speed. Basically as of right now, only Uprev is supporting the Z. Cobb only supports 2009. Uprev offers mail tunes as you are already familiar with. Also offered are tunes from Uprev tuners, but you have to go back to them for adjustments. Lastly, there is a tuner version that allows you to pay $50 for a mail tune, or take it to any competent tuner and have it done. You must download the software from uprev onto a laptop and plug the cable into your OBDII port and usb in you laptop. You can do diagnostics, read & clear codes as well as tune on the fly. I recommend checking out their site to get up to snuff on it.

What is the world coming to...?

Thanks for the information. Whats the deal about coming from a Mustang to a 370Z. Both are beautiful cars in their own specific ways. With my Mustang I dealt with American Muscle for parts. Is there an aftermarket dealer for the 370 that would be on par with American Muscle in terms of great reputaion and customer service?

Thanks again

Plenty of forum vendors that support the community. There is a section for them too. Also if you check new posts, you will see them bumping their products.

Lol, because 70% of us go from 370Z to 5.0

We have great vendors, but expect to pay more for 370Z parts

Well I've been in the Mustang world for a while now. I've owned 6 in the last 10 years and have modified the majority of them. The handling of the 370 is much better than the 5.0 IMHO and as with any car TQ and HP is only a few bills away. Essentially by the time May rolls around I will be driving a 370 that will chew my 5.0 and handle much nicer. So can you list some of these great vendors?

Jeez thought coming to the 370 world would come with some pride, not people confused on why I made the choice lol

Cheers

Welcome to the forum. Perhaps see you around this summer

Thanks for your reply. Got me heading in the right direction. Cheers!

Thanks. Question for you, did you do any aftermarket ordering for your 370? If so can you point me in the direction of which vendors you used.

Thanks again

what kinda parts u looking for? basic bolt on stuff or like forced induction or what?

I've used Z1 performance, Corner3garage, b2autodesign, GTM, and a few others. Not everyone has everything, so you might have to develop a few go to spots to get what you want/need

To be honest I have about 20k to start with and I'm currently interested in doing complete exhaust work (headers, highflow cats and catback), break upgrades (rotors, pads and lines), cooling components if available (ie high flow rad, oil cooler, break coolers) flywheel, clutch, shifter, driveshaft and some suspension (swaybars, control arms, shocks, springs etc). If funds allow either a turbo or a blower setup but I have a funny feeling I'll have to hold off until the following summer because most of the installs will be done by a speed shop.

In the past this tends to run my bill up rather quick (example my 2006 Mustang with roughly 26k in parts cost me a little over 9k just for the installs). Ideally in the end if I can have my 370 putting down at least 400 RWHP (either N/A build or F/I build) I would be satisfied. I haven't looked yet but another member said parts are pricey, so hopefully I can get as much as possible done with the funds I have available to start this project.

I started this thread because this will be my own little reference point. Like I said I've been in the Mustang world for a while now and know very little about imports, specific builds and aftermarket part vendors. Essentially all responses on this thread will help me build my project and I appreciate any info.

Cheers!

No need for driveshaft, it's already carbon. HFC's and Long tubes can only be done with Fast Intentions or Motordyne's exhaust systems. Or you can buy a mid pipe back of anything and just buy a Motordyne Y pipe and HFC. Both excellent companies. Most who run long tubes, don't use a cat.

If you are trying to reach 400whp, I say go for a GTM supercharger kit and breather mods. Don't worry about the headers. The car has a decent set of equal length shorties anyways. Get an oil cooler asap, 25 row minimum. Replace the brake lines and pads, get some good fluid for your brakes. If you are trying to buy all that, expect to pay over $20k regardless of who you buy from, we have to pay the Z tax.

400+ whp is going to take boost of some type. 20k isn't a bad budget for a good FI build.

I was just about to say that!! seriouly guys get off the mustangs ball sack!! I'm not suprised... i picked a my z over a 07 GT500 that was paid for. just couldnt do it. once i got into my 350Z?370z i didnt go back to american. Z pride.

You guys need to post more often then :p There're several longtime forum members that have moved on to Mustangs from their 370Zs and they are quite vocal about it :icon17: We need guys like you to step up on behalf of the Z haha. But seriously, it's all in good humor. Real car guys respect car guys :tup:

I was unaware the driveshaft was carbon and that the exhaust manifold is a equal length shorty, good to know.

Thanks

I'm looking at this site with all Stillen made parts. Does anyone have any pos/neg feed to share? I'm only asking because its looks close to a one stop shop which I prefer instead of shopping from multiple vendors. Any thoughts on the SC as well?

http://www.stillen.com/

Stillen isn't bad, but there are better products. Their CAI is pretty stellar on the other hand. Most agree that GTM has the better supercharger kit. Some however have had success with the Stillen unit. Again, I recommend reading all the feedback on the forum, there is a $hit ton of information and opinions.

Pretty surprised that the usual "mustang defense force" hasn't shown up to spread the sweet gospel.

Anywho, looks like you have enough to either completely pimp out the Z with a NA build which would put you around ~340whp, or start a FI build.

Z1 and GTM were used alot for my build. Keep reading on this site and
there is tons of information and interaction. Basic start is exhaust then
new intakes. But if you want to go further look at GTM kits they seem
to be some of the best on the market.

Cheers

Welcome... Hey I came from a Porsche 996TT to my ZR and I really enjoy it. I will also go for the power in the near future. This is a great group of people that will give you great advise and or tell you to use the search button lol! I personally want to try the NA mods first CBE, HFC, CAI & Tune then after a while if I want more power go for the FI build!!

This isn't a bad plan, but you may be spending a lot of money on parts you have no use for if you go FI.

Boosted performance turbo kit, FI Exhaust, tune. $13k give or take a grand or so. 5kish left over to go towards suspensions and brakes. More stopping power. Better handling. 500ish whp. Done. :tiphat:

True enough. Maybe I'll start this build a little bit different than originally planned.

We've had so many people call us fan-boys for loving our cars and trying to push the mustang agenda, that one-third of our members fell into subjective brainwashing and became self loathers for owning a Z.

So this is a Z forum that glorifies, 5.0's, the C7 before it's reviewed and used porsche cayman S's. Lastly if you believe your Z may be able to win at a track against anything American or German? Be prepared to argue all day.:eek:

Enjoy your Z.:tup:

Would it only be the CAI that you cant carry over and the CBE & Cats stay with the FI ? None the less I still want to explore the NA mods because all mods are fun :tup:

I came from an 06 stang GT and I gotta say youre gonna love the Z 10x better! However, your first post is almost the exact same as mine was when I made the switch, and I have unfortunately found that the Z world is not fortunate enough to have an americanmuscle.com style source that offers parts and free tunes for life on the good ol sct :( Basically, after you finish all your breather mods (CAI,Exhaust,HFC, and manifold) then you have to take it in to a specialist tuner to get it done. and pay money for it! I know it sucks when SCT was so freakin easy and free. These Z guys dont know what theyre missin on that deal. At any rate, the Z is a different animal, much more refined. You will love it! :)

From what I have read: GTM is the way to go on forced induction, from super to turbo (twin superchargers looks sick), on the NA side though look to stillen/fast intentions/Z1 to get what you need.

Waitin to see your build!

Fast Intentions has a turbo prototype right now that seems like a fluid build that's coming out with strong preliminary numbers. Based on F.I.'s history and reputation on here. I wouldn't jump any guns on buying turbo's till you get to see this upcoming TT for our cars.:tup:

http://www.the370z.com/forced-induct...r-pics-28.html

You would definitely be ditching the CAI. Cats would most likely go if you went with a turbo setup. The CBE you could keep if you get one that flows well enough to work with FI. A good 2.5" exhaust would be fine. If you're going to do a bunch of bolt-ons before you go FI, you may want to buy the CAI and cats used. Might save you some money since you'd be turning around and selling them later.

u have $20k to spend??? ooooo man. 500+whp here u come.

single or tt kit - ~$8k
upgraded clutch and csc - ~$1200
exhaust _ $1000-$1500
tune - ~$500
install - ~$3K (not sure on this one)
oil cooler - $600
ebc - $500


$5k left over

Add to that an oil cooler (MUST HAVE ITEM), electronic boost controller and some aftermarket gauges.

If you have additional money to spare, FAT tires.

good catch. added to list

Also need test pipes and or high flow cats. If you need cats get a exhaust set up where you can add cats after the test pipes. Your cats will last a lot longer that way!

Real quick though. A lot of power mod suggestions, but this car won't handle that power well without an improved suspension and our brakes can use some improving.

Suspension
Sways_SPL linkage system_KW V3 clubsport/Robispec'd or Swift sprigs on Koni yellow or JIC Magic FLT-2, Or StanceGR+ to make a truly good suspension and 3 budget options.

Stoptech sport brake upgrade kit & Stillen brake cooling kit
Z1 brake upgrade. (aesthetically, my personal preference is StopTech)

Lighter weight wheel package (volks)
More aggressive tires... Michelin pss or Bridgestone RE-11.

Welcome to the forum, I've always loved Mustangs and since I was a kid have wanted one, one day I probably will have one some day.
That being said I also have always wanted a Z just as much (my first car was a Datsun).

I there are two main reasons I chose my Z, and it has nothing to do with which is faster, because they are both blazing lay fast cars.

For me it was about styling and handling, and also about how many are out thre on the road. The other day I had a nice Mustang pull up next to me and I looked over and thought it was a pretty nice car, but then I looked in my rear view and saw another one, and then another one in the oncoming lanes across the intersection. Maybe that's a testament to the cars popularity, but I've always enjoyed being sort of in the minority, but knowing what's best.

I've always been that way (i.e. I've been a Mac computer user since 1990, back when they were at their lowest, but I always felt they, we're better, sleeker and a better design.

Again welcome to the Z :tiphat:
