That’s why I just enjoy the car for what it is. Decent speed with solid reliability. Lowered, wheels, exhaust and a nice sound system. Done. ✅
I thought this was about the "redline" Q60. the price point between the NA Q50 and Q60 is HUGE...but the Q60 is turbo and has 400hp and a crappy transmission that can't really handle the power anyway
Was literally just wondering if I should tune my ‘14 Q50, hoped on YT and saw your vid at the top. Much love!
Awesome man! Yeah really just have to decide what you’re going for. Loved the process and tuning my 15 but doing it again, I’d focus on the other stuff first.
Same here and i also have an awd model so its heavier anyways😢
@@SpeedCultureStudiosother stuff like what and i wanna know which q should i go for the premium or the sport is there really a huge difference that’s worth the extra 2-3k?
@@Ghstlyy bumper, brakes and seats is the main difference. If it's only a 2k difference, then yes I'd say it's worth it. Brake upgrade is easy, but it would take about $1,000-1500 any way. Either way, I'd focus on the things I mentioned in the video.
As a G37x owner, I feel the N/A mods are priced too high. May as well do forced induction off the bat; just have to make sure the car itself has its maintenance up to par.
With that being said on a boosted setup these have near unlimited aftermarket support and loads of potential with minimal mods
That’s a truthful statement
3.7L was a great and powerful engine back in the day. Compared to the modern forced induction motors, tuning a N/A motor is just going to be splitting hairs. I got almost 186k miles on my 09 g37x sedan. It's an excellent car to hoon around in. Stock power is still fun in most conditions
I'm glad you made this video. I regret getting test pipes and tune, I "built" most of my exhaust myself so it was cheap. On the dyno my car did 302.5hp and 240.82tq stock, after tune did 315.37 and 257.58. So a gain of 12.87hp and 16.76tq. Not much at all but the graph looks a lot cleaner. Despite the small gains, it's never been as fast as it was stock. I ran a 4.76 0-60 before the tune and haven't seen less than a 4.8 since. I'm not even sure of what to think of the numbers anymore, I'm just tired of the VQ37. Also it doesn't help that my gas mileage is 13.6 average. My original goal was to shoot flames but then I started growing up and being scared of exhaust tickets.
If it makes you feel better, 0-60 is not really a good indicator of performance improvement after a tune on the vq37. It’s not a stop light to stop light car because it’s not all that torquey. The gains are in those higher rpm and higher mph points. The improvements seem to come more on the 1/8 to 1/4 mile runs where you’re getting to use that peak power.
I had a VQ37 for about 10 years and recently sold it and picked up a B58. The truth is just that the mileage sucks and the car isn't even *that* fun for the mpg. I can totally understand living with 10-15mpg in a Hellcat or Corvette, but not in something like this. My total average after 10 years was 17.6 mpg and that was driving like a grandma for the last 7 after I stopped going crazy with the car. The new B58 gets 20mpg+ when I drive like a madman and has so much more power. I'll always have a soft spot for Gs and Qs but if you're looking for performance, they just aren't it anymore!
@@SuLu_XD b58 is a strong motor!
@@SuLu_XD which b58
@@ghstly5257 2010 G37x sedan -> 2020 M240i xDrive. I'm currently stage 1 tuned and planning on stage 2 in the spring with a downpipe and mid pipe. Currently pushing about 380whp at stage 1 and stage 2 should push me to 400whp or slightly over.
I have a Q40 and I agree with you like 100% like the mods for this car are like really really expensive and for what to make 30 to 50 more horsepower with full bolt on e85 and having horrible gas mileage just to be “fast” and then you race like a newer car and you lose
On my q iv done muffler resonator delete with a tune bc i wanted the burbles im either gonna get drop ins or a intake nothing crazy not dropping alot of money on my daily but my next car either gonna be a lexus is500/is350 or a red sport and thats when ima drop alot of money on the cars
Careful with the burbles when you have stock cats. It’ll tear them up
I agree with you completely. I was really close to buying a 2015 Q50 and improving handling seemed like a better route bang for your buck wise.
Appreciate this video. I've got a '14 3.7 that just hit 200k, and I've been debating a lot on whether or not to squeeze out that 50 or so hp. So far, the only thing I've done is got the z1 upgraded sway bars and links. New tires as well. I think the focus on handling instead of raw power is a great way to enjoy this vehicle. Thanks for your videos man, you've been a great resource for owning a Q50!
Thanks for checking in!
@@gauntlord9423 Really shouldn't tune a car with 200k miles on the ODO, infact most tuners won't even touch it.
@@Aharon999Yeah, true. I wouldn't be concerned about the engine, but the tranny I'm sure would give out soon after
@@Aharon999 Yeah I agree. Too much risk, not enough reward. She's been a great car, can't complain. The extra hp and sound of the SCS exhaust setup was the only reason why I even thought about it lol
intakes and exhaust work , and handling and breaking and looks on the outside is what i'm looking forward to doing
Good plan!
I’ve debating if I’m tuning my 13’ G37x. I’ve done drop ins, ported manifolds, a full exhaust (stock headers) and the typical aesthetics. I’m struggling with minimal power gains vs tune cost.
Shaved half a second at the quarter mile after the tune. Not too bad!
No not too bad at all
What do you think about the 3.0 transmission swap in a 3.7. Been seeing it done. What's your thoughts about it?
It’s a good upgrade. A little spendy but seems to eliminate the valve body issue and can handle more torque so good if you’re going nitrous or forced induction.
Coming from a 2006 IS350 I have been pondering buying a Q , after seeing how crazy the top end is on the 3.7 and seeing how it hangs with several other vehicles that are faster much like my IS but the opposite lol from being fast to digs , switching to rolls.
I have always loved N/A style builds but I’m stuck between something turbo or another N/A import (I do not trust the VR30 unfortunately)
The 3.7 is a fun car. You are right, they like to be up there at top end high rpm range.
I have 2015 q50. I’ve put long tube headers cat back exhaust wheels, ported upper / lower manifolds, big bore throttle bodies (76mm) 3.5 inch intake piping . Injectors. Fuel pump . Tuned on e85 /93 . Suspension and exterior upgrade. Brakes. It’s worth it if you spend it wisely. Not all at once . But would I do it again absolutely because every guy that has a car . Be Whatever it is , has done something or continues to do an upgrade on their cars. It’s just what we do lol. 😂
It is indeed
what about for an awd?
Same applies - lsd doesn’t apply quite as much so I’d put that 500 toward light weight 2 piece rotors
there’s plenty of avenues to building a car- budget, average, over the top. for example: straight pipe + alibaba test pipes, isr + berk test pipes, or a full Motordyne setup. waste of money is subjective to each person building their own car how they want to- either for looks, performance, drifting, etc. i don’t think tuning a 3.7 with some bolt ons is a waste of money, but there’s more efficient ways to make use of your money IF performance/speed is your goal and that would be boosting and skipping the “fbo tuned” phase.
That’s true, but a totally different video.
3.0 is the way to go if you want speed. Learn how to mitigate the issues they have and maintain it properly and it will last and be a lot of fun 💪🏻
Good advice!
What about putting that money into a mid mounted turbocharger for the 3.7?
Its a good chunk of change to throhw at it but wont get you all the way. You’d probably want to do a trans upgrade at that point too
Hey everyone, does anyone got any ideas for my fx35. One day I was driving and all of the sudden my slip light and abs light came on the dash. When scanned it shows nothing but it still shows on my dashboard. What can be causing this? A sensor ?
I think N/A cars just take a lot to go a little faster however I wouldn’t say it isn’t worth it. I have enjoyed every bit of gain and every step of the way in my G37x and I’m not even boosted yet. If you’re truly into cars you already know this isn’t a forgiving hobby. We have 100k cars competing in events paying out less than 10k every weekend and in my opinion the vq37vhr has way more potential than the vr30tt but that’s for another discussion. So I’d say start where you can, take the steps you can when you can and enjoy the journey or if you’re disciplined enough save up and do one big step but however you get to your final form…..enjoy all of it, that’s what makes it worth it.
I agree! like I said, I had a blast and enjoyed the tuning process. Just having done it already, I personally would prioritize other areas first.
My 2016 3.0 got stolen this week. Is there another car you’d recommend that’s similar to the q50?
Definitely a waste of money. I spent so much on my NA 3.7 G coupe. Got a tune and only made 326hp to the wheel. Still felt slow. I ended up buying a 10r80 5.0 and I tell you it’s scary to drive compared to the VQ
Night and day to a v8 😂
Quick question what type of tune you did when you had your Q50? And if I may ask do you know what is the range pricing for that certain type of tune you did? Also I’m pretty sure it don’t spit flames to much like on a regular basis
I rarely used the flame map. Ecutek is the software brand.
I have a 15 3.7 full invidia exhaust berk resonated test pipes already on the car, I have short tube headers that I haven’t installed yet can I run my headers with my test pipes already on?
Test pipes will work with short tube headers.
However your 2015 q50 already has the updated exhaust manifolds from factory compared to the previous year models. Going short tube headers is not worth it and you won't gain much power.
Not to mention, header installation on the vq37 isn't a simple job like installing test pipes or cat-back exhaust. It can easily be a 5+ hour job if you've never done it before. Drivers side can be a nightmare. It's tight space to work in.
Also the invidia exhaust is the worst performing exhaust you can buy for the 3.7.
The inner diameter of the piping is narrow. Every other aftermarket exhaust for the 3.7 on the market is 2.5" piping minimum. The invidia is like 2.3"
@ preciate you I was planning on getting a new exhaust setup anyway before getting tuned cause the invidia sounds terrible on these cars. Will adding the short tube headers make the car louder than it already is right now with the test pipes or is it the same?
@@_rbswifty short tube will be louder
What about weight reduction? I know Q50s are on the heavier side I’ve always wondered if it would make a difference if it was tuned and gutted
Reducing weight is always helpful -- and usually free!
Why ruin such a luxury car by gutting it, think a 370z would fit best for that
@ it’s all about what you’re going for. It’s fun to make something out of a car it was never intended to be.
You seem to have changed your tone a lot on the 3.7 Q50.
Nah, spent a lot of time on supporting mods like brakes and suspension. Just saying I’d prioritize them this time.
I have a 2011 g37 sedan tune with 3 inch intakes,ark cat back exhaust and berk resonated test pipes and my best 0-60 is like 5.4 does the vr transmission makes that difference???
Also I’m on 19 ipl wheels z1 suspension and ksport coilovers don’t think that’s gone make that big of a difference
I don’t know about the vr trans on the g.
No lies told the 3.7 is no rocketship i just gotta say i a g37 had about a car and a half on me a coupe months ago against my stock tune VR i was kinda shocked 😂
My n/a g37 with bolt-ons & tune put 5 car lengths on a vr30 q60 with catless downpipe, cat back exhaust, intake and STOCK tune. This was from a roll 40 & 50 roll.
It was my co workers car. I installed his down pipes, and we went racing afterward. I was surprised how slow the vr30 on stock tune was despite all the mods.
Tune a vr30 and it's making mid 400whp all day
Well yeah lol the VR30 has a very mild factory tune. They make 30hp less than a VQ unless you have a redsport.
@@menace2society00 most stock vr30 (non redsport) make 300whp.
Most stock vq37 dyno 270-285whp
@@sleepy_ipl They are rated 300 crank from Infiniti themselves. They might have slightly underrated them but most dynos of a stock Q50 VR30 non RS is about 286. They practically make the same power stock, of course any type of tuning or mods will wake them up way more than a VQ
@menace2society00 true, but you're kind of splitting hairs here. Your original statement was vr30s "make 30hp less than a VQ" which isn't true. That would mean they're making 250whp
Few may be putting down the same as a VQ, but honestly, the majority I've seen on a dynojet are putting down ~300 to the wheels
Hey. Love the content bro! I am really stuck between the ‘15 3.7 or a ‘20+ 3.0t my simple question is which will last longer and cost me less maintenance? I am really wanting to go 3.0t but maintenance concerns me. Thanks bro!
I have 3.7 and I would say it cheaper to maintain 3.7 than the 3.0t i have mine for 1 year now and have managed to put like 25k miles on it and no really major issues except when the transmission valve body went out and it was fixed under warranty but the best thing is to swap the transmission from a 2019+ into it and you don’t have to worry about anything else, you probably will see the transmission for 800 to 1000$ and labor work be around 850$ but the valve body itself cost 3k so to me i will pick the 3.7 instead of the 3.0ts that comes with turbo issues and some can have cracked engine blocks with it being stock so to save yourself from them headaches 3.7 is the way. That’s my opinion
@ Bet I appreciate the reply. The more I question it I just believe I should do 3.7
15s are getting old now, but you don’t have to worry about porous block or falling turbos.
Do you want the car to go fast in a straight line? Because the 3.0t is a baby gtr if you want it to be the 3.7 is a pretty bullet proof daily that's still fun to drive.
Get a b58
Brakes and Tires will make all the difference.
Huge but rear sway bar was a game changer
Or do both , I would say do a nice exhaust, and some headers , than worry about handling
Do both-I’d just priorities one over the othrr
The VQ37VHR already comes with almost 100% of its potential from factory... doing an N/A build is basically a waste of money in my opinion.
Depends on what you mean by “build.” Bolts and tune, no. Actually building the engine, there have been some pretty sweet VQ builds that rip.
@
Yeah I meant only bolt-ons with stock motors... because doing FBO tune a 2006 Altima even with stock cams you can get around 270whp VQ35DE at 6,600 RPMs, on a 3,170lbs car that's very good.
The reason why so much WHP is because Front wheel drive is about 5%more efficient than RWD, especially with a manual transmission, 270whp on a stock VQ35 is possible on altima/maxima.
If a tuned 3.7 can beat a stock redsport why not tune it
Not exciting to say you need a tuned bolt on car to beat a stock car…
Agree you’re better off getting g37 coupe or 370Z instead mfs gon down talk you if you own 3.7L q50
Better off with a g? I wouldn’t say that. Slower, older, and a worse reputation.
@ a 2011-13 g37 nicer looking either way better carbon fiber parts better quality
If you talk about wasting money, can't that be said on about every hobbie? Let's be real, a non car guy can look into buying a turbo is a waste of money. Just do want you want. Who cares what people say. Come on bro, you could do better contents than this.
I don't think you listed to the video at all lol
Just get the 3.5 and you’ll be at 360 hp 😅
That’s not wheel hp though.
No reason to tune a 3.7. Car is honestly slow even with bolts on and a tune. Not worth the money. Better off just getting a faster car.
It’s hardly “slow.”
@@SpeedCultureStudiosYou driving the Audi should make you aware that the 3.7 is slow. Relatively speaking.
3.7 is not worth it period
Worth if you like reliability
Nonsense
who would waste thousands on a depreciating liability which was overpriced to begin with? would make a ton more sense to save that money for the endless repairs to the engine and turbos and tranny which will inevitably occur. these are money pits and you could waste huge amounts of wealth. if you want to go 0-60 in under 3, get a Tesla or Rivian and don't follow the path of ruin as you explore the ever present check engine lights and carbon build up, and valve bodies, etc.
God forbid someone have a hobby.
He’s Talking About A 3.7. The VQ37 Is Reliable And Doesn’t Have Direct Injection Or Turbos. The VQ37 Can Hit 200k Miles EASILY While Doing It Reliable.
Exactly
I think you’re mistaken here bud. The 3.7 is a pretty solid platform. Aside from that, people spend thousands on cars because it’s a hobby. They enjoy it.
