This package is a great bridge between stock and turbo and relatively budget friendly. Even if you stay FBO this kit still would be fun. Even if you decide to go turbo you still can keep the upper and lower intake manifold and exhaust . There might be some ppl that will try to duplicate this kit but with top of the line exhaust, intakes and headers will spend A TON more and end up with the same numbers.
Also remember, Z1 has already tested this kit. You aren't messing around with slightly different brands and or fit and finish.
There is alot of validity in what's being said however, you can YANK that Crank number down pretty easily without using the Z1 Kit for way cheaper.
Custom CAI-System (Consisting of Proper Piping with slots for Sensors and lines, 3", Silicone Couplers, Gold Wrap and Quality Clamps) - $300
Set of Ebay Test Pipes -3" - $125
Quality Exhaust Gaskets -$80
Factory Piping removed and I managed to replicate the SCS Exhaust package you recommended MINUS a Y-Pipe as I am now True Dual from front to back 3" diameter with labor for installation - $-700
Thermal Spacer and Lower Plenum Spacer - $200
E85 Flex Fuel Kit w/450lph Pump + 1000CC injectors (For future mods that will involve forced induction) - $500
$1905 In parts and Labor, leaving off the fact that I was already tuned. A Ported Intake Manifold is USELESS on this application, it's plastic, you cant achieve the same surface smoothness with it that you can on metal because it doesn't take to polishing the same, the airflow over the surface will never be as smooth and never move with as much velocity as it would over a metal one to matter, and even getting a bigger TB and port matching it only compounds the problem because you get MORE air moving MORE chaotically at possibly slower speeds. Manifolds are at their most efficient when air FLOWS in uniform INTO ignition chambers, not tumbling which is what will more then likely occur from an attempt a porting a plastic manifold. THAT Said...with this set up and tune i saw 377whp and would wager i spent far less then the Z1 400whp kit. Honestly, your SCS Exhaust recommendation is better then anything Z1 offers, Im surprised you're not pushing a Self-Created Kit of your own composition over anything from Z1.
I definitely recommend the SCS catback over everything, which I did suggest in this video lol. It's the best bang for the buck, no doubt about it.
Who are you tuned by? The dyno most likely reads higher than it should cuz those mods should get you 340 whp at best
@6MT.V36 once at Top Secret again in Florida at Circuit, Dynos fine and I've added more and retuned since then and am well over 400 crank after cams and head work. 4.5L stroker block incoming along with boost and 6spd conversion next. Making power in these things N/A is easy you just have to keep your goals realistic and avoid time on the rollers playing it safe. I did my own motor and assembly so I tune for max power and reliability not safety and I'm on either E85 or straight race gas ALL the time.
@@TheOmegaSanction I have a Manual G37 Sedan with 3 inch long tube Intakes ISR Long Tube Headers & Single Exit Catback made 310 whp On 91 pump gas On the dynapack tuned by Saul nismo Knights and I’m beating other Vqs that have higher dyno numbers than me & I really wanna get to 350 whp what cam are you running? I’m hoping cams & e85 will get me there
@6MT.V36 you don't even need cams. The single exhaust is hurting you tbh, it will fuck with the valve overlap that the Vq motors need to make efficient power (and why they usually see so much gain from exhaust mods). 3" CAI, upper and lower intake plenum spacer, I did go BIG Throttle body and had it port matched (90mm) but for the money I spent I still don't think the gains made it worth it, bigger injectors and fuel pump were essential, you got the long tubes already so u golden.
I'm tuned for 93/E85/E90/C16, finish what you started you can def yank down way higher then that 350 number trust me you almost there.
I have intakes, hcf and exhaust so at this point I might as well port my upper and lower manifold and swap the hcf and headers for long tubes... Great content thanks
I had a Fast Intentions 2.5" dual x-pipe cat back exhaust, a Stillen Gen 3 long-tube intake and a dyno tune using EcuTek software. We got 321 peak rear wheel hp with a 15% uniform increase in torque across the rev range. I'm estimating that the engine is producing about 381 hp at the crank.
What about MPG?
@@e7bk My highway mpg stayed about the same but I did lose about 3 mog in stop and go driving.
Can you make a video explaining the tuning process and the different options for getting your car tuned.
That's a good idea!
!!
My G has long tube intakes, ported upper and lower manifolds, resonated test pipes with full exhaust, light weight single piece drive shaft, 3.69 diff, tuned on ecutek. Now I’m looking into upgrading my torque converter cus I blew my stock one 😎
Good combo! Love the gearing too
🫣looking in the background and noticing the truck cap on the Titan 👍🏽
Video on that scheduled for next week 😉
I'm not an expert when it comes to horsepower but Don't the VQ 3.7L comes with around 330 hp off the lot? So why adding that 400 HP package if at the end you will be around the same stock HP numbers?
That is crank horsepower not wheel horsepower. They make about 285 horsepower to the wheels stock. This 400 hp kit is also crank horsepower so it’s about 345 horsepower to the wheels.
Maybe we could link up one of these days for a drive been watching your q50 videos since I bought mine
I have 2014 q50 pushing 350whp running custom single exit also still on stock manifold and stock headers .305torque
What are your other mods? those are rather high numbers even for the most healthy VQ.
@@SpeedCultureStudios isr high flow cats 3 inch y pipe and my 3inch signle exit . Also 3 inch UPT intakes they go down all the way to the bottom grill for max air flow . And E85 ofc. I have dyno sheet
@@eliworld8745 I was skeptical - especially with HFCs - all the way until e85 😂 Then it made more sense. I could see approaching 350 on e. The 300+ torque is the real surprise though.
Do the long tube headers being in the grill suck up raid and bog the motor? i had a subaru that had this issue and not being able to drive in the rain suck
There is potential for it, yes. Best thing to do would be to put the filter bags on them.
@@SpeedCultureStudios I’ll probably just do dry drop ins tbh. Rather not deal with that it rains almost every day in New England this time of year
Would I gain any hp if I port the both Tbs on my Q50 3.7
Can you explain why you're promoting this package now when in a prior video called "5 mods you absolutely don't need" you mentioned most of the parts from this kit aren't necessary to get most of the hp and trq gain? I heard you mention the catalytic converter and tuning was most important to change. I intend to push my VQ37VHR engine on my 370Z to a balance between as much increase in hp/trq with maximum reliability. To keep it NA and get the maximum miles out of the engine while also performing as much as it can. How does anyone know when it's required to mod instead of stick with oem for a goal like that?
Not necessarily promoting but updating since my first package review from several years ago. The package itself has changed and tuning on the vq37 has gotten better. Yes, the main pieces of the puzzle are test pipes and catback with a tune. Headers instead of test pipes might get you a couple more hp peak and maybe a bit in the midrange. The long tube intakes probably won’t get you too much for power but will help keep temps down when pushing the car for prolonged periods.
Like I said in the video and in past videos, it can be done cheaper or you can get 95% there, but for convenience and uniformity, this is a good kit. Or you can just get pieces of it. Just depends what you’re going for. Bang for the buck, convenience, or peak NA power…
@@SpeedCultureStudios ok great, thank you sir.
Do you think that the short headers in the package are necessary because the g37 oem exhaust manifold are very similar?
They benefit the G more than the Q
Good video man. But they do have long tube intakes for the q its made by Upt they are 3’ so it requires a tune
Thanks! That's not what I said though--I said you can't take the intakes in this kit and use them on the Q.
Do you have them installed on urs wanted to know if it’s worth it?
The 2.5 in CAI doesn't require a tune to run. Any Cai upgrade requires an eventual tune because you're adjusting AFR but you can bolt these on and drive.
Soo I installed the SCS exhaust. And test pipes, drop in filters . Dyno tuned with pop map .. I got 300 HP .
Later I installed the long tube intakes and e85 with tune again .. I’m at 365 WHP
Valuable information
That's about 400 crank. Did the same thing in 2017 full Motordyne exhaust and manifold with stillen intakes ,megan long tube headers on E85. Got 365 at the whip also
Your first tune does not sound correct or it was not done correctly. Filters, test pipes and any catback (but definitley SCS catback) would have gotten you 320+ in a G37. 330+ in a Q50. No way on earth long tube intakes and E85 would get you 65 wheel horsepower gains. That first tune was no bueno.
@@SpeedCultureStudios to keep it short that’s what I thought at first. I was a little disappointed . I was following everything you did and expected the same numbers as you or closer.. but I guess everything depends on the tuners numbers.. I guess he can show these numbers while other tuners shows different numbers, but will have the same power . . I didn’t get it. With the first time I didn’t feel anything till I did the retune. Now I feel the powaaaaa I love you Brother !! 🚗 💨💨💨💨
Can I ask who tuned you?
That first power number is off by -30hp.
If you still had the q50 3.7 would you do nitrous or a single turbo build?
They are so different in so many ways lol. Nitrous would be easier to do and MUCH cheaper. Turbo would be awesome but quite expensive.
What type of tires are you considering? I’m patiently waiting for Uprev to get their tune ready but once they do, a significantly higher speed rating tire is going to be necessary and I can’t find anything.
The Firestone firehawk indy 500 has been great for me. Love the Advan apex on the corvette but they are very soft and will wear out fast
I’ll be be going to inman muffler later this month I wanted to install my diffuser first
Good idea. You’ll want the diffuser on for reference when deciding placement of the exhaust tips.
@@SpeedCultureStudios my thoughts Exactly
i know we all saw the 370 pull up behind right as he started talking about it
Lol good catch
Hey I live in Greenville too who do you go to for your mounting and balancing work and time?
I’ve used Amazing Grace Tire for most tire mounting and balancing.
PPE equal length headers = win; those plus the fast intentions exhaust with carbon fiver mufflers = classy for us old folk!
Then Z1 supercharger
Done!!!
Go annoy corvettes and porsches 😀
Have you considered trying to team up with a brand to sell the scs exhaust?
Obviously you’d have to sell it for more than you originally paid to have yours done, but if you could make it with really good quality for less than a competitors exhaust I think it would make you money and help the community also.
Just a thought. Great video as always my guy
of course. The big brands like Borla--although I have been going back and forth with David Borla the last couple of weeks -- are just not responsive. It takes huge investments for R&D and they look at a platform like the Q50 and just don't see the volume to justify. It's unfortunate.
What about the. 3in intakes that goes in the front for the q50?
Not worth it on the Q
@@SpeedCultureStudios ok got tuned about two weeks ago made 327wph 265wtq with just full exhaust/test pipes tune but want to make more power
@ewwitsdavid97 if you want more power you need long tube intakes,long tube headers and e85. That will net you 345-355 whp.
@@v36vhr got the 3 in intakes long tube headers over priced e85 not enough station put honesty car feels faster with 3 intakes underated mod for q50
@@v36vhr long tube intakes will not get you any additional power. They do help with mitigating heat soak but will not provide any additional power. Especially not in the Q50.
Do you think dyno numbers online get influenced by other things people don't mention or disclose? Like wheel weight, tire weight/grip, lightweight 2-piece rotors, 93 octane (or higher), outside air temperature, etc. You see great numbers all over for this platform, but all tests are not created equal is basically what I'm saying.
Yes obviously there are a ton of variables. No two dynos read the same either. You just have to sort of look at the averages. Wheels and tires have an impact heat and humidity have a major impact. These cars need to run in premium anyway so all are tuned on 91-93. Generally I’d they are using anything other than pump gas or have gone e85 that is disclosed. But yes, there are a number of things to keep in mind. But there have been such a huge number of these cars dyno’d with similar mods so we have a fairly solid idea of what the numbers will be before making the first pull.
@@SpeedCultureStudios Thanks for the reply! Appreciate the channel.
@@wesdriver no problem man. I appreciate you checking out the videos!
Whats the % of drive train loss for an AWD 3.7 N/A?? 🥺
What about the Q70 3.7?
Probably just same as Q50
Do you think I could make 400 crank hp with just intake, cams and shortails on a 370z nismo? I want to avoid test pipes and headers, just too loud for me as a daily driver. I'm trying to find the quietest way to make 400hp without going fi... I'm hoping the cams will make a decent amount on their own after seeing Z1's video?
With cams probably, but you could do HFCs and intakes and get almost 400 crank and spend a fraction that you will pay for cams
@@SpeedCultureStudios That's a good shout as well but I think HFC are still too loud. I've heard them in person and it's still too much for me as I daily drive my Z.
To avoid doing cams, I'm thinking intake, intake power plenum mod, shortails and a custom tune will get me pretty close to 400 without touching the factory cat.
will I reach similar numbers with motor dyne shockwave, art pipes, stillen gen 3 intakes, tune, on 93 tune?
Port the manifold and you're just about there!
Are you sponsored by Z1? Cause if you aren't you should be lol
Thanks lol
@SpeedCultureStudios what's your thoughts on a pedal commander?
@@v36vhr they really haven’t done much in my experience. Some people love them.
#VR30 gang no need for all this work around on the Q 😬😂
And we don’t have to worry about porous blocks, snapped belts and blown turbos…
@@SpeedCultureStudiostrue but 90k miles and car still running strong on Z1 turbos 💜💜💜 but still love the VQ own a G35 with the DE 😬
How can someone go on about making their 370z oem exhaust louder without spending a lot of money and without losing torque/hp?
Check out some of my exhaust videos. Ultimately tuning after drastic exhaust changes is the best bet to keep torque numbers up. Other than that, going the custom route with a proper design will prevent torque loss and get you the sound you want
@@SpeedCultureStudios i checked out many of your videos but you don't really address the topic of muffler delete that results in torque/hp loss with dyno tests on same day to prove. I want to do muffler delete but where can I see how many hp/torque it loses? I might get aam short tails or maybe just custom muffler delete piping (no tune)
What do you thin?
IMPORTANT NOTE: As of this comment (8/10/2023), Z1 does NOT offer this package with the sedans (unless I overlooked it). Also, it is NOT available for AWD vehiclea (again, unless I overlooked it).
If you have either sedan or AWD you might as well make your own. You can still get the intake and manifold just do the scs exhaust setup and get long tube or just test pipes and save some money
The only thing that may cause an issue would be the exhaust, but that’s a small problem.
Would this work on a G37 sedan tho 🤔🤔
Essentially everything except the catback.
unfortunately, the headers are not available for who knows how long. So, the package is no longer available.
It’s ok-the VQ factory headers/manifolds are actually quite good so without them you’re only missing a couple hp
It's Dyno proven that high flow cats have a maybe 1HP difference than straight pipes.
It really depends. I’ve seen 5-10 hp differences in multiple cases.
That's a lie! Hfc are almost same as regular cats! Str8 pipes definitely more than 5
Like #300 😂
