I installed Broken09 motor mounts last night, here is how we did it.

*First cut a block of wood to fit under the oil pan in between the subframe.

*Unbolted the motor mount bolts and jacked up the engine with the block of wood via the oil pan. I only jacked it up around 3 to 5 inches, just enough room to unbolt the mounts.

*used a box end 17mm that was curved? so that it reached the bolts. On a couple I was able to get a socket wrench in there.

*removed the mounts and fitted the passenger polyurethane mount easily but had a problem with the driver aluminum mount.

*I had to hachsaw the bulge on the mount. It was a big chunk of metal and I also removed rubber that was seared on the mount.

*At this point I found myself without a big enough washer to cover the hole for the passenger mount. So I used the washer thingy that secures the mount to cover the hole and secure the bolt. The piece I used, a rectagle piece of steal that fits perfectly over the top of the mount and lets the bolt sit just right.

*the bolts (header bolts) I used were way too long so I had to dremel them down at bit. I also had to use extra washers in order to not run out of thread. I wll use a correct size bolt as asap.

*Once I had the mounts on the core. I reinstalled them and place the poly washer below the subframe secured by metal washers.

The mounts are really effective, the car feels more solid and the response is much better. The bolts I used are too long, however. I bottomed them out a few times on some high speed runs but I will dremmel them some more.

I highly recommend anybody wanting a alternative to the more expensive polyurethan motors mounts to pm Broken09 for more info. I posted this in the advanced tech section but wanted more people to see an alternative to more expensive polyurethane mounts.

Very nice, I will say the mounts are stiffer for sure. I used a set of Jaguar XJ6 on my FD. They are harder than stock but softer than polyurethane, at least the 94 shore ones. I made my diff mounts using urethane/94 shore and they came out great. The cost was under $50.00. I am now designing a diff brace which uses a mount. The solid ones are not for me.

 

Great write-up!

But I'd recommend using the flat part on the bottom of the tranny as a jacking point, still using a piece of wood as a cushion.

The oil pans are pretty flimsy and using it as a jacking point could easily dent it.

 

Thanks Garrett. I appreciate the positive feedback!

 

what is broken's price for both mounts? Everything included, what misc. stuff did you need to buy?

 

pic's???

 

I charged him 90 for the mounts. I plan on including the mounting hardware you need with the next sets I sell so that you don't run into any problems. If I can get enough interest I can get the materials at a lower cost which in turn means I'll charge less. I'll try and take pictures of mine tonight or so.

I wish I had pics of the installation but don't have a camera. The mounts are black and come with a polyurethane washer.

Broken09: No problem, you saved me from having to pay 350 dollars for mounts. I'll take that deal any day. More money for other stuff.

 

Well I'm glad they are working out for you. Good to hear!

As for what will be included in the kit:
1) both mounts (you will have to tell me which mounts you have since there is a possibility of having two designs)
2) 2 urethane washers
3) Bolts, nuts and hard washers.

 

And I garuntee your satisfaction if you get them and don't like them you can return them to me and I will refund your money.

think you could PM me some proposed group buy prices, maybe i could organize one, since I'll be needing these parts as I'm sure others do too.

 

I'll put prices together tonight, look for a PM later tonight.

check pm

 

hey if you could send my some pics id like that

 

Check the thread in the for sale section about the deal I'm running on them now. I posted a couple of them there.

I'm in. But can you get some more pics. I am a machinist, so I just want to see how the mounts are done before I Pay.

 

I'll see what I can do. Unfortunately my set are on the car and the only other set I've sold are to Garrett. I will have to see if he has any. What in particular are you looking for in the pictures.

I saw the pics. Do you rework the stock mounts to fit the new urethane ones. What is the aluminum piece under the sub frame for? I am using two cast mounts right now instead of one aluminum. The aluminum one tends to rip more often.

 

Will you stand by it!

 

I'll be helping a friend do his pretty soon and I'll be sure to drop some feedback on them.
