Street Unit Motor Mount Install!!!!!!!!!

OK i got my motor mount yesterday and installed it tonight. Took about an hour and his going to require a few things to do the job.

A friend to help at the end
15mm socket and 1/2 ratchet
car ramps (suggest ramps not jack stands for this as you takes some tugging and pulling and you do not want to knock the car off)
hammer
screw driver
floor jack (blocks of wood maybe required if your jack is not tall like mine)
lock tight

here is what you start with


place jack under oil pan with blocks to make sure you do not damage the allum pan and take some press off the mounts


remove the 2 15 mm bolts that hold the large and small end of the mount. The motor is still under some pressure so it is going to take a screw driver or center punch and a hammer to tap the bolts out. The motor is going to move so or at least mine did so do not worry.

once bolts are out the mount will just fall out. here is what it looks like. the small end is very weak. the slots are open all the way thru and you can move it around with your hand no problem.




Here is the new Street Unit mount. Very nice part very well made from what i can tell.



Now it is time to reinstall the mount. The only problem i had was that the small end of the mount is very very tight. i had to use some lube on it to get to start and go in place then take another floor jack and press fit it into place. That is the only thing i can see worng is that the small end of the mount may need to be about 1 to 2 mm thinner than it is. But it may be designed for a very tight fit. What you have to do is instal the small end first like i said abot with the floor jack so that it presses into place. once the bolt holes line up just install the one both with the nut that has the end welded onto hit to hold it while you are tightening it.


Once you have the small end in place you will need your firend under the car with you. He(or a very strong she) will need to push up on the motor to help the big end rotate into place so the bolt holes line up with the mount bracket. once it is lined up get that bolt started and tighten it up then finish tighening the small end bolt as well. That is it you are done




DISCLAIMER This is how i did mine. If you follow my instructions you do so at your own risk i take no responsibility for anything that happens to your car. Thank you

PS i have taken it out for a drive a couple of times and i love it. There is more vibration at idle but it is not to bad. i know my wife will hate it but it is my car and her Escape is the family Veh now so does not matter. I went out side of town and launch faily hard and the tires did spin and NO WHEEL HOP Plus there is more power getting to the ground for sure. It spun the tires alot more than it has. My friend that helped me was riding with me and just could not believe the diff. Over all this is a great PERFORMANCE MOD. If you use your fusion for a daily driver family car and like the nice quite comfortable ride this is not for you but for us on the forum that want to get everything we can out of the car this Motor Mount is for you.

[/quote]Yep it surely is and I will stick with it for a little while yet, but if this doesn't smooth out soon I will put the old one back in and sell this.

Update: Actually things are getting better but I've noticed that my idle drops below the set 750 with my Steeda tune once in awhile and only then does it vibrate appreciably but for the most part from 750 on up it's been fine with little vibration. The overall benefit has been very favorable I'd say and when I get on it, it just feels solid as a rock during acceleration. Having said all of that I would personally recommend it :goodjob:

:cheers:

Def agree. the fee is much better. you can tell the drive train is not twisting as much with this new mount which is def puting more power to the ground. The motor mount will loosen up over a 1000 to 1500 miles. mine has. i hardly notie the vibration now at idle. Jeff with your tuner can you ajust idle at all? If you can maybe try and set it at 800 RPM or something that may help keep it from dropping to low in gear since you have an auto.

Once it loosens up over 1K to 1500 miles it is great and will work for daily driving. mine does not have hardly any vibration anymore.
[/quote]Yeppers Dan, it has gone down considerably and feels great now. I'm not sure of adjusting idle from within the tunes options as I've never gone in there but only loaded them straight up. I will check sometime today...anyhow here's a pic form the other day during the mount's install...

[/quote]Update: I now have approx 1200 miles on it now and I can say it's a whole lot quieter and hardly noticeable now. I still however have this variable idling at times that causes my H-brace to rattle up against my down pipe but I haven't been in to adjust the idle speed as of yet.

ya same here. i have about 2K on mine and i hardly notice it at idle any longer. But still great when it comes to hard launches and shifting.

On the same note- have you guys seen the trans mount yet or looked into it?

http://www.awrracing.com/store/product_info.php?products_id=405

I know it says its for a speed6, but I'm assuming it should fit. They also sell a comparable motor mount for less.

sl8tr- do you know anyone that has the 6 point version of your H-brace? I know its 3 times the cost but I wonder if it ties everything else in that much more?


http://www.therpmstore.com/product_...d=340&osCsid=eac1461b6ed521d54ca402a0437d92bc

The reason I'm asking is I'm thinking of doing this all in one shot along with the STB and still holding off on Steeda and the endlinks before I buy the rear sway bar. Thanks guys.

[/quote]I know I'd be definitely interested in a trans mount if it would help but not sure what's out there. I looked into the VF Engineering mount at F2 for the mazda 6 and asked Ricardo if it would fit the fusion and he said they tried but no joy. So I'm guessing that a speed 6 tranny mount wouldn't necessarily fit it (Fusion) either. I'm hopeful that SU will perhaps come up with something soon if not already...
 
#38 ·
i would not think the tranny mount is the same as both the stand 6 and the Speed6 have diff trans from the fusion. The cases on them would be a little diff so the mounting locations would also be diff. As for teh 6 point brace i know there are guys on the Mazda6 forums that have them and love them but cannot see how they would help that much more. At least not that much more for the price of it. The H brace works great and love it.
 
#39 ·
Darn- on the trans mount. :( H-brace- thats what I was thinking. Two more points for $120 more! I can see it tieing everything in together tightly but for 3X's the amount? Man your shooting everything I see down. LOL. Thanks. Hence why I ask before I do. You guys have had your cars longer.

Ordered the Motor Mounts like 20 mins ago.....
How long was the instal and Slater did you follow the original write up?


Bought the Smoked Side markers as well.......

[/quote]

it took me and a friend about an hour with hand tools. I did not use any air tools or impact. Alli used was a 1/2 ratchet and sockets. There were no instructions when i got mine. i wrote the fusion instructions for SU to use. you will want to have a friend with you to help as you will need to rock the motor a little to get the bolts started.
 
#42 ·
Installed the Motor Motor mounts today, I was kinda suprised by the vibration at start up and at low RPM's but it could be worse.
Hope the pics help a little bit, didnt need to do a write up because Slater took care of that for all of us.The second pic is where the Mount got stuck even with some Red Lube on it. It took a rubber mallet to literally beat it into place, along with a prybar to swing the engine a tiny bit to align the screw holes (<------ ?)

Anyway, hope you guys enjoy!

What does the motor mounts do exactly? how does it imporve from factory? :shock:
[/quote]

it keeps the motor from rocking back and forth. When the motor moves to much it puts the axles in a bind and causes power loss as well as wheel hop when you spin the tires.
 
#46 ·
Hey Dan, I didn't see an torque specs listed in your write up and my SU didn't come with any directions.....that I found at least. I'm going to do this later tonight or tomorrow. Is the loctite necessary or is that something that you just do to make you feel safer? I don't remember seeing any on it from the factory.

Thanks.

*Update-I torqued them to 90ft/lbs because that seemed to be about right where they were. I used blue loctite (dunno if the stuff I had was even any good). I don't know if I did anything differently then the rest but here is what I did and it went together as smooth as glass.

I loosened the bolts till they were about to come out. I supported the motor pan as Dan did. I then jacked it up until I could remove the bolts by hand. I then re-installed the new mount, larger side first, sliding the bolt back in with loctite. I swung the smaller end up into the mount and got it roughly half way in before it got tight. I then used a solid rubber mallet and tapped it in 4 times until the holes lined up without any lube, put the bolt in and gave it a soft tap and slid right in.

The only thing I can think of that might be different is that I live in a state where there is no snow, no salt and the car has hardly ever seen water other then when I wash it. They might have changed the mount or SU could have shave a few mm's off. Who knows. I know I did it by myself in less then an hour. Took me longer to get the car on stands and back off then anything. I did check again and NO- didn'tget any instructions other then return information. I'm going to drive it right now a few miles and let you know what I think of it when I go to work tomorrow.

sorry i did not get bck with you my computer crapped out. as for getting the mount in i know the guys at SU were going to take some off the mount so it fit better. after my install and a couple others they said that it was to tight. so i think that it must be fixed now since yours was better.

Possibly. What about the torque specs?

The initial start up was wild! Funny- now at idle the car seems to want to die and idle's lower. I'll see how it goes after about 100 miles tomorrow.

i also put mine at 90 foot #'s. Seemed right to me. As for the shaking at idle that will smooth out over about a 1000 miles. so start driving :lol: but it will smooth out over time. the mount just needs to get broken in a little.

It's already gotten better..AND- my banging of the H-brace is back too. So back to the coat hanger and scratching like a cat at start up...grrrr..

BTW- I am totally impressed with this mod. The less torquing of the motor makes a substantial amount of difference in clutching from a dead start and it almost completly resolved my issue of the 1-2 shifting I have complained about for 7 months now! I am wondering if my cable's were off somehow? Whatever the case this thing is stiff and agile now all round. Now what else can we do.....LOL

ya it works great for me as well. the main reason i wanted it was to cut down on the wheel hop. and it has done that. it has snowed a couple of times already and that is when it would wheel hop the most and it had not done it once so far. Very happy with it.
