Upgrading my Engine, Transmission & Rear Subframe Mounts To Polyurethane & Billet Aluminum

[@tonycampbell9626]

Milan your videos are very focused and instrumental as if you are teaching a class. You and AnthonyJ350 set the standard. I just wished the KZbin community as it pertains to the Z platform could follow.

[@daeshawnr2595]

The shine of that exhaust and undercarriage is awe inspiring😍. Rust truly is the devil😂

[@milanmastracci]

The truth has been spoken!

[@roninmantis7584]

As always, you make the best videos. You cover each section to the project and have time markers to find it easily. Well Done!

[@milanmastracci]

Thank you very much!! I appreciate it Ronin 👊

[@4G12]

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.

[@milanmastracci]

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!

[@joedapro555]

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.

[@milanmastracci]

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.

[@adrianreyno1]

Amazing work. You're meticulous which pays off in the end. Every mod helps in accomplishing great performance.

[@staypositive4358]

Wow! This is amazing! I have no intention of this doing right now but loved it! Very professional and clear presentation! Thanks!

[@milanmastracci]

Thank you for the kind words! Its a great mod, and I would strongly recommend swapping from rubber to poly 👍

[@JBaek24]

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

[@milanmastracci]

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.

[@ahmaddabdoub1696]

Jae, I agree with you. The best 370Z/VQ content on KZbin. Both entertaining and super informative.

[@milanmastracci]

Thanks for the kind words guys! ❤️

[@DJDirtyFunk]

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

[@ahmaddabdoub1696]

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.

[@milanmastracci]

LOL I'd be down for that! I don't think they offer sponsorships, but it can't hurt to ask 🤙

[@torvarrisevans7254]

Hey bro would recommend the z1 engine for g37 6mt

[@TheCamaro1987]

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.

[@milanmastracci]

That's awesome! How is your throttle response now with all of those mounts? I'm really looking forward to upgrading the diff bushings!

[@TheCamaro1987]

@@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.

[@milanmastracci]

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

[@chachakeepit1hunnit996]

Keep it up 👍🏻 love your videos so detailed and informative!

[@milanmastracci]

Glad you like them!

[@feraskhouj7675]

Hey, I know I’m a bit late to this, but I’ve just upgraded my engine and transmission mounts with the Z1 mounts like you did. However, I’ve noticed an increase in vibration, which is annoying during casual driving. I’m not sure if the vibration is coming from the engine or the transmission mounts. The engine mounts were necessary because I installed short headers, which were hitting the steering column during cornering due to the engine movement with the softer OEM mounts. Since I have a 7AT transmission, I’m now wondering if the transmission mount is the main issue and if I should consider switching back to the OEM one.

[@Jondakilla54]

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!

[@milanmastracci]

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?

[@Jondakilla54]

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.

[@bchnts]

Great mods and I believe that they don’t have any downsides

[@milanmastracci]

It doesn't seem like they do either! I would 100% recommend them

#pro That's the way a How-To is done! Bravo!

[@mattrosich]

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

[@TWOINF_Z]

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?

[@milanmastracci]

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!

[@TWOINF_Z]

@@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.

[@candyapplez3438]

Awesome videos man!

[@JimmyJenkinJohnson]

Quality video. Thank you.

[@jeremygalloway1348]

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

[@milanmastracci]

You are correct! The bushings as a full set work tremendously well together. I would 100% recommend it

[@sherlonio507]

This is my dream Z, all about handling full SPL inside there!

[@milanmastracci]

Handling before power! The only way I mod my cars 🙌

[@geary4260]

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.

[@JustBetterShorts]

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.

[@Hondacbr600rrish]

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.

[@milanmastracci]

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.

[@spicywater123]

You dont have to remove the exhaust manifolds to do engine mounts on a 350Z, I've never tried it on a 370Z.

[@Qkfltpdls777]

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!..

[@DeifVideos]

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

[@alfredpalsson]

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?

[@milanmastracci]

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

@@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.

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.
