Limiting the movement of the engine?

[Nebo]

When my car is under boost my uicp seems to slip of the gm sensor I have. I think it is because the sensor does not have a bead around the edge and because I might have to much engine movement. I have recently replaced the motor mounts with new oem ones and do not want to go to a harder set. I know when I have an rx7 we would limit the engine movement by either using a fixed strut or a piece of steel cable from the block to the front of the cross member. Has anyone done this on their dsm or have had any problems with engine movement??

why not just stiffen up the front mount and leave it at that?

Here's one way of stiffening the mounts off the old DSM FAQ's....click on engine then...engine mount inserts.

When I did it, over and above the polyethelene, I also used 3M glass adhesive that is rubber, black and is used to fill in both sides of the mount up to the edge.

Get some epoxy and make beads on your MAF.

Make sure you are using halfway decent clamps, as well.

Put hairspray on the hoses before clamping them.

why not just make a front motor mount (if you have access to a welder)

I made mine in about an hour and it is probably one of the best things I have done to my car driving wise.. even with inserts the motor still rocked bad.

Procedure:
1) cut a piece of 1/4" flatsheet metal 2" wide x slightly longer than the original mount
2) mark the bolt holes and drill holes in 1/4" bottom
3) place a grade 8 nut over the hole and weld into place
4) cut a piece of 2x2x1/8" box tube about 3" long
5) place the base where it will be mounted on car and sit the box tube where the hole for the mount is centered up inside the box, then mark its position.
6) weld the box tube to the base where marked
7) place the mount in the car and start the bolts to hold it in place.
8) place a jack under the front of the motor and jack the motor up to place tension on the rear mount (will move about 1", I used the exhaust housing of the turbo)
9) mark the hole position on the box steel
10) drill the marked holes out with the same size hole as what is in the original mount (7/16" I think)
11) install mount, remove jack
12) ????????????
13) Proffit
14) enjoy the slumbers of faster throttle response the the ground, crisper shifts, and a all around better feeling car.

I would take a picture but it is so tucked away you couldn't see much

Seems like alot of work...Look $100.00 get you a full set of Energy Mounts and they work great.

total time - 1 hour
total cost - $0

If you want you're intercooler pipe to stop blowwing off, Or the coupler.

Spend $7.00 and buy a tbolt clamp. It wont come off no more

Prothane mounts are sweet, they eliminated a ton of movement.

Well most likely if it doesnt have a bead, then its probably the boost blowing it off not engine movement. You just need to bead it and clamp it good, dont worry about engine mounts, i seriously doubt thats your problem, without a bead pipes blow off so easily.

I second the t-bolt. But the cutting board/windo weld is a great solution for all of us without welders.
