If you have ever reved or dynoed your car you will see how much the motor moves on stock engine mounts. Therefore we have just introduced the Injected Performance Solid Motor Mount for the 2003> Nissan 350z and G35. This exceptionally crafted motor mount is made of .120 wall Chromolly with TIG Welded plates on both ends for a secure assembly. Pair includes all necessary lock washers and Grade 8 Nuts and are powder coated gloss black for an exceptional finish.

 

Pardon me for asking, But what is are the advantages and disadvantages to having these?

 

and the price is?

 

Advantages include less movement of the motor during higher RPMs, and higher horsepower cars. If you can have someone rev on your motor you will see the motor move a considerable amount towards the passenger side shock tower. The solid mount eliminates this. In higher horsepower applications, the motor can move a considerable amount that could ultimately cause mechanical pieces (such as the twin turbo kits) to stress against the torque of the motor and could also hit the body of the car. Another advantage is we can custom make a mount to have the motor sit lower in the car which lowers the center of gravity (Good for track cars). The mounts we have produced set the motor at the correct ride height. The stock mounts under the weight of the motor alone drop 1/4" to 3/8", with the torque of the motor the passenger side mount will compress and the driver's side will expand. This eliminates this play.

Disadvantages are you will feel more vibration as the stock mount has a rubber insert that takes most of that vibration away.

holy freakin crap that's stupid expensive

the ones I bought from overZealous1 are working just fine and cost $120 - and I thought even THAT was a tad on the expensive side but since they weren't available anywhere else it seemed the way to go.

These do look nice though, not sure if they lower the engine lower like overZealous1's do

I have nothing but good things to say about mine. Anyone who comes in here saying it'll rattle your teeth out or the vibration is a lot, well you haven't driven a Z with solid mounts and my 115 lb wife who's even prone to migranes from vibrations thinks you're a wuss - the vibration isn't bad AT ALL

it turns your engine into a strut bar, gives you less wheel hop when launching, if it lowers your engine that's a better center of gravity, you get more power to the wheels with less power being used to move the engine so it instead turns the driveshaft harder, shifting is better by keeping the transmission still, they shave 5 lbs off the front cause the stock ones are bulky and heavy, you will NEVER have to worry about something rubbing due to the engine moving again, if you want a grounding kit - well the engine WILL be grounded to the body with the direct metal contact, etc etc - awesome mod, though you have to remove or lift up the engine to put them in

When I had mine put in, the shop really cautioned me asking if I'm REALLY sure, and that I'm probably just going to want to put the stock ones back on. When they first saw them, they laughed cause they're so much more hardcore than the stock big fluid filled rubber ones. Well I'm glad I had them put in - extremely glad I did. Very proud of having the mod despite all the caution - I took the gamble and am so glad I did

 

Sorry if you think they are expensive. Haven't seen the other ones for $120. These keep the engine at the stock height to make sure all intercooler piping, turbo kits, etc. fit properly. We can make ones that lower the engine more in the the engine bay.

 

Yeah, the SVRT one are just as nice and I paid like $110

 

Yeah pricing seems a bit high. Scott(SVRTechnologies) look exactly the same for $120. They use grade 8 bolts and nuts as well. http://svrtechnologies.com/7.html

 

The motor mounts we have developed are much different than the ones below. The ones in the link, have a bolt that goes through the center section. I assume you have to put the center mount in, then put the bolt through the subframe to the upper mount or vice versa. Our bolts are welded to the actual mount itself in which there are two fastening points, therefore there will be absolutely no play between the center section and the threads or bolt shown in the picture below.

 

I couldn't find it on the site, what material are they made of?

 

his are made of Dom steel I think

and

https://my350z.com/forum/engine-and-drivetrain/170802-solid-motor-mounts.html

 

has there been any failures to date?

 

SVR strikes again!

 

Ours are completely mirrored off of stock mounts as you can see below. Therefore there are no seating or bolt issues.

Stock Mounts:
Top Mount: 3/8"
Bottom Mount: 1/2"

Injected Mounts:
Top Mount: 3/8"
Bottom Mount: 1/2"

 

I'm sure the Injected Performance mounts are better. My installer said if he was making solid mounts for the Z, he would have done a few things different than the SVR ones.

still though, they work and I love them

 

mine are made from 1.75 dom steel with 3/16" round ends tig welded on. actually i thought you had a set of my mounts when i first saw the pic, identical looking. btw- the dom i use is the same material used for nhra certified roll bars. could not even imagine the crush strenth, like 100,000lbs+ lol. the bolts i use are also 7/16" grade 8. bairily fits through the upper hole, but it does. the through bolt works perfectly fine and takes all the pressure off the welds and creates a sandwich out of the whole assembly. they do not walk around on the threads, lol. installation is also easier due to not having to lift the motor as high to slide them in as the through bolt can come up straight from the bottom. realistically, they are almost identical. the materials both of us are using are well over and above anything that the mounts will ever see.

basically the only difference would be that i use a through bolt and injected welds bolts to the end plates from the inside (i'm assuming here) then welds the ends on.
not trying to jump in your thread here, just wanted to clarify how mine were built as that seemed to be questioned.

 

overZealous1,

No Problem at all. I have never seen your mounts before and have not tested them personally so I can't say anything good or bad. Same goes for our mounts. We have tested our mounts in 1200hp Supras with no problems at all. I just don't think they are the same. Similar design, yes, but there is only so far you can go on an engine mount.

 

Alright, solid motor mounts might be the solution to a minor problem I'm experiencing... APS ST crossover pipe is hitting the firewall during the hard acceleration... If motor can be dropped lower there will be more clearance between the crossover pipe and the firewall, and if the motor doesn't move, pipe won't hit.... That will totally solve my problem!! About the increased vibration.. How bad will it be?

 

That is some amazing tig welding..nice work, IP.

I'll be using these mounts on my engine, once the move to Marietta is complete.
