Upgrading my Engine, Transmission & Rear Subframe Mounts To Polyurethane & Billet Aluminum
Вставка
- Опубліковано 28 чер 2024
- After throwing a tune on the Z, I was somewhat disappointed as I was expecting the ‘throttle response’ to the fixed, and it wasn’t. After driving my car and pushing it more, I was able to determine which areas of the drivetrain needed upgrading.
The stock mounts on my Nissan along with 95% of production cars, are rather insufficient when you push them beyond their intended design. It doesn’t matter if we’re talking my comfortable FWD Accord, or even my sporty RWD 370Z, the bushings are wayyyy too soft if you want to have a good connection with the car.
Just like the previous video about the Coolerworx shifter, this upgrade will give you a better feel for your car, and will be beneficial for both on and off track use. I hope you enjoy!

The shine of that exhaust and undercarriage is awe inspiring😍. Rust truly is the devil😂
The truth has been spoken!
I love how you're approaching this car, Milan. A billet or stupidly stiff polyurethane set of mounts might be ideal for pure track and race use, but racecars are beaten hard without much regard for long term longevity and livability during normal street use. These mounts significantly improve overall handling and safety of the car without compromising chassis longevity and comfort since they still absorb the vast majority of the metal fatigue inducing high frequency vibrations but are actually stiff enough to hold things where they should be on low frequency motion inputs such cornering, accelerating/braking.
I appreciate it brother! 👊 I try to tackle mods systematically. If you've been around for awhile, even with my MINI, more power was never the first thing. Handling always came first!
As always, you make the best videos. You cover each section to the project and have time markers to find it easily. Well Done!
Thank you very much!! I appreciate it Ronin 👊
Wow! This is amazing! I have no intention of this doing right now but loved it! Very professional and clear presentation! Thanks!
Thank you for the kind words! Its a great mod, and I would strongly recommend swapping from rubber to poly 👍
All the other videos where time lapsed when it came to the rear subframe. A++++
Good video. I did the same thing, adding stiffer bushings and mounts. Different car same concept. Everything you've said is true, this is the way it should have come from the factory.
Thanks Joe! Yeah its insane how much of a difference it is. Even driving the civic, bone stock, it feels so 'sloppy' compared to this now with the upgraded mounts.
Keep it up 👍🏻 love your videos so detailed and informative!
Glad you like them!
Awesome videos man!
I don't have a Z but do I wish you owned all the cars I have so I can follow your DIY steps. You're very good presenter and instructions are top notch! My S2000 engine, trans, and diff mounts helped as well and subframe collars, but being that it's a low torque car... you don't "feel it" as much I think
I'd love to my get hands on an S2k! I've heard they're amazing street cars. Yeah I can see how you wouldn't notice as much of a difference. I feel it also has to do with the OEM design of the mounts.
Jae, I agree with you. The best 370Z/VQ content on UA-cam. Both entertaining and super informative.
Thanks for the kind words guys! ❤️
Going to SOHO motorsports this week to get my Z1 diff bushings and my CMAK external slave cylinder installed. These look like good future mods as well. Good luck on your build.
You're going to love them! I should have done them sooner 👍
Just did the subframe collars today. Thanks for posting this video to reference.
Glad I could help! How do you find them?
@@milanmastracci only slow rolled around neighborhood since it was raining yesterday. Haven’t ripped it yet. On slow roll seemed tighter in rear.
Quality video. Thank you.
Have the same mounts. Plus the poly diff bushings on my G37 6MT that is similarly tuned (UpRev) and you are absolutely correct. Huge improvement without much cost and little to no downside.
That's awesome! How is your throttle response now with all of those mounts? I'm really looking forward to upgrading the diff bushings!
@@milanmastracci hard to remember what it was when still stock, it was very sloppy. The diff bushings, then tune, then mounts, then lightweight flywheel each improved as the build continued. Coilovers in the next few weeks so I am excited to see the change in handling characteristics.
Hey bro, can you if torque solution transmission mount made a difference in performance , I wanted one for g 37 6mt
Man your videos are like chrisfix quality, how tf do you not have more views?
Getting these on Black Friday this year for my Z!
Gonna be so awesome to upgrade! You won't regret it. You should pick up the diff bushing too. I'll be changing mine out when I yank my diff out
Great vid Milan 👍👍👍
Thank you! 🙌
Your car is so clean !! 😍😍
Nice video but looking forward to Mini ones 😝
Thanks Dorian! They will come 🙌
Love the Z platform!
That makes two of us 😉
Dude every time I watch your 370z videos I literally go to Z1’s website and buy more parts. In today’s case just waiting for Black Friday to order upper and lower intake manifolds, and now I’ll be buying these mounts for my 6MT G37 sedan. Z1 should def sponsor you.
I also live 45 minutes away from Z1 meaning I can have these parts the same day which doesn’t help.
LOL I'd be down for that! I don't think they offer sponsorships, but it can't hurt to ask 🤙
Hey bro would recommend the z1 engine for g37 6mt
Great mods and I believe that they don’t have any downsides
It doesn't seem like they do either! I would 100% recommend them
The transmission mount was super easy to install only took 20 minutes and surely feels like it puts down more to the wheels. But do realize the car will have more sound and vibration
#pro That's the way a How-To is done! Bravo!
Beautiful 😍
I know you are but what am I 😉😂
This is my dream Z, all about handling full SPL inside there!
Handling before power! The only way I mod my cars 🙌
nice! i have poly mounts on my evo 2, both engine and the whole suspension, with balance shaft delete and damn my whole body gets massage every time i drive. it is not a daily by any means
I just got a 2017 with 56,000 kms.. I bought the car certified and I didn’t notice on my short test drive but I think the engine mounts need replacing and or maybe tranny mounts.. I guess this is a common issue with these because it looks like Z1 sells a ton of them. When I gear down and release the clutch it takes 1.5 seconds before it engages. When I press the gas there’s a delay in momentum and if I let off the gas my head jerks forward 1 second later.. does this sound like a mount problem ??
BTW love your videos, super detailed and professional.
Honestly can’t wait for the diff video. I did my own Diff and mounts, I went with the Tomei LSD and the lock up is great but sometimes the clicking can get really annoying. Probably something wrong I did, but from the looks of the forums it’s normal. I will probably change it out eventually to a helical LSD and go away from Clutch lsd.
The fluid definitely makes a difference. If you do end up going with tomeis 1.5 LSD, instead of shelling out $50 for their fluid, I’ve used an equivalent GL-5 80W-90 fluid like valvoline and mixed it with a bottle of friction modifier and it works perfectly fine and doesn’t click as much. I tried to give redline a chance but it doesn’t work quite as well.
I also have the same color but a 2014 Base 6MT. Currently pushing 340 whp and 272 wtq. Tuned with Tomei and Z1 cold air intakes. I love the progress of your car and it’s perfect since I get to see what wheels would look good on my car while you do all the work haha. Awesome videos and keep it up!
I'm pumped for it too! I'm going with the Nismo GT Pro 1.5 Way. I like how it is adjustable, without having to disassemble the diff. I'm okay with a bit of noise here and there, as long as it performs well!
I have lots coming for this car, and I know you'll enjoy it if you've upgraded things like your diff already! What mods do you have that got you to 340?
milanmastracci My setup is Z1 cold air intakes with test pipes and ISR Y pipe. Paired with a Tomei Catback. The single exit exhaust is the biggest gain I believe. Since my friend has the same setup except he has dual exit. Eventually I’d love to go FI but whenever I’m actually willing to spend those funds.
I like how you say eouwt
Do a video on that diff bushing
I will for sure! 👍
YEAH BABY WE GET AN EXHAUST VIDEO. BENEFITS OF STAYING TO THE END OF THE VIDEO.
Hell yeah 🤙
Good job. However, you need jack pads (looks like hockey pucks with a middle slit) for those jacking points or you'll ruin the frame.
good!
Great video...but those bushings compliment each other...cofunctioning together to minimize movement. When you upgrade one but not the other...the original will deflect more...so it's not a fair comparison to both original bushings or both upgraded. But still cool to see how they interact
You are correct! The bushings as a full set work tremendously well together. I would 100% recommend it
Nice bro, does the engine mounts really makes a difference,
Thank you for this! Was wondering will the Z1 trans mount fit a automatic? Thanks
Pretty sure it Only doesn't fit the AWD models
That transmission mount made my car vibrate so badly I put the OEM one back in. It’s also fully adjustable, but comes with no adjustment instructions. So it’s possible I had it adjusted wrong.
love me suspension mods especially all the ones that help w/ the wheel hop! that $hit is the worst!
So true man! It's such a great feeling when everything comes together 🙌
Love your clarity and directions in all your videos. I was curious on your point of view about a issue I've been having. My steering shaft u joint connection bolt seems to get caught on the heat wrap around my headers only when I break and take sharp right turns. It never does when turning sharp left or while driving normally. With your best judgment do you think the Solid Motor Mounts would keep the engine from shift on me?
The upgraded engine mounts will definitely help with the engine from leaning onto the steering shaft & the u-joint. What headers are you running? I ran into this issue with my OBX headers, however after switching them out for PPE headers, I've had no issues. The engine mounts will be a solid move in the right direction. I don't know if I'd suggest changing the factory mounts for solid ones, but polyurethane was perfect for me. Stiff enough to prevent the engine from moving in the engine bay, and still more than tolerable in the cabin from low NVH. Hope that helps!
@@milanmastracci thank you for your thoughts and I have the ISR shorty headers wrapped with Motordyne Art pipes. The polyurethane looks and sounds much better then going solid, I'm just curious how much more added cabin noise it will make considering it's already high now with full exhaust changed out.
good luck with that rear diff bushing lol get your sawzall ready
Can't wait 😂 I heard its a PITA to change, but I'm up for the challenge 👍
@@milanmastracci oh its fun stuff lol you got it tho bro 💪
I ask you question. Im considering the transmission mount. Can they fit it Q50 VQ 3.7 sedan? let me know.
Why didn’t u put threadlocker on the transmission mount bolts? And it looked like red threadlocker was originally on the bolts. Why didn’t u use that? I’m not questioning you by the way. Just curious. You clearly know what you’re doing. So I just wanted to know why u did it this way. Thanks. Love the video
hey man nice job. is that the original paint on your car? I was wondering what that color is called. I have a 2004 Touring and the silver is darker than that. I want to get it repainted a brighter tone.
Hey man! If you have an 04, that means you have a 350Z, so I don't think all of the paint codes continued on for the later Z34 vehicles.
Hey bro what seatbelts do you have installed ?
hi, i drive an 08 g35s w/ 5AT.
i have new vibration at idling (even when the car is fully warmed up) after installing new aftermarket (ebay, Westar) engine and transmission mounts, but i had no issues with 16 years old mounts…
Is it because they need some break-in period until they mounts settle in by themselves?
Or shall i check each nut’s torque again? (I don’t think the mechanic used torque wrench…)
Or is it because they are cheap low quality mounts?..
Please advise me!..
Its one of those mods (like sway bars) that have no downsides to it, and not that expensive either
Couldn't agree with you more! 🙌
I'm fairly new to all this. What's the benefit or importance of a high performance sway bar? Thanks!
@@staypositive4358 I had a set of Hotchkis anti-sway bars installed on my 370Z sport coupe and the difference in handling was significantly better, at the expense of a somewhat harsher ride. The car is much more responsive on the turn-in and has nearly no body roll on cornering. There is less front-end drop when I go over a driveway dip at an angle, and so my chin spoiler has less tendency to scrape the ground.
@@videomaniac108 . It makes sense. Thank you so much for the reply!
This is very important for the Fiat Abarth, not the one with the MX-5 body- the mounts fail and might cause one of the CV axle joints to fail.
That is very true! The mounts in a FWD platform are more important than RWD since everything happens up front! I've gone through multiple axles on my Accord since the mounts were so soft
So my 6mt g37 shifter moves a lot (like forward towards the engine ) when I accelerate mildly
Just installed my z1 trans mount and that didn’t fix my issue
Just ordered z1 motor mounts , do you think this would fix my issue
152k OG motor mounts so I’m assuming so if anyone has had same issue pls chime in
Hey Milan, where did you get all the specs of the torque for the screws and nuts from?
From the factory service manual 👍
The car looks like it’s new underneath here in sweden all the cars are rusty from all the salt on the roads. How many miles does it have?
40k kilometers = ~25k miles. The only reason why this looks the way it does is because it doesn't see winter, and it hardly sees rain. Any vehicle here that sees winter looks absolutely atrocious, even vehicles a couple years old..
Hi Milan, apologies for this off topic comment. I'm hitting a little snag on my 09 Accord coupe. I'm replacing the door seal, driver's side. There is plastic body trim holding the gasket along the bottom. I can't find any fasteners. Does this trim snap out somehow? Thanks, appreciate the help. Tom
If you give it a little yank upgrades, it will unclip itself from the door sill area. Cheers!
Thanks, I'll give it a try and let you know. Regards Tom
Hey bro , would you recommend the z1 transmission mount. Does it really helps with performance
I found that Z1 trans and engine mounts to tidy everything up. I would for sure do it again 👍
@@milanmastracci thanks
did the motor and trans mounts decrease the movement the shifter has?
It did, drastically!
Can you install engine mounts with removing headers?
Yup got mine done today at a shop - it was very tricky and a ton of work.
15:37 are your jacks directly on the frame rail??? Won’t they bent?
As long as the car isn't rusted, they shouldn't budge 👍
How's the shifter holding up? Chase that rattle down?
Good! I adjusted it a bit so the shifter is moved back a bit, but the rattle is still there. It is a bit annoying but the gear changes are so precise!
Since you're gonna see the accord, would you consider selling the throttle body spacer 😂?
I mean I don't see why not lol
Question is the coolerworx short shifter universal?
It is not, however they do make a ton of different shifters for different applications.
Me: Staring at wth piping in engine bay. Got it just do the trans mount
Where did the sexy rims go?
LOL which rims are the sexy ones?
@@milanmastracci The Black Rays that you had
I agree where did those go
I sold them to some guy with a stanced 370Z. I think he's tracking on them 🤷♂️
@@milanmastracci Still thinking of getting new lights and selling those? Let me know if you do.
Where’s the si content?🥺
Coming soon! I have a couple more things to do for the Z, then I'll be going full send with the civic 👍
Is that a greddy exhaust?
The next video will be going over it, along with the other exhaust upgrade 👍
First
🙌
So you fell down or something?
??? Did he say something about falling down?
@@dreednlb look at his eyes... there is some black mark around it. So asked.
@@ankurpatkulkar5021 I just watched it again. I don’t see anything unusual about his eyes. What time in the video are you looking at?
@@dreednlb At the very start of the video, there is a clear dark mark under his right eye over his cheeks. It was there even on his previous video as well. If you still don't see anything different, watch his 2weeks old video "Foam Cannon & Pressure washer setup" one (beyond 7.40 minutes you'll be able to see his face clearly). Following him for 3 years now, definitely remember that was never there before.
Check out my last post on instagram 👍 @milmast
You're going to get sick by that vibration. don't do this to your daily, or you get constant head aches or worse getting scrotum cancer😂😂
