He forgot to add BDC's preferred material for engine mounts...... a block of scrape 2x4 from home cheapot.

You all laugh because you think I'm joking. He actually defended it.

Remember the old adage?
If it's too good to be true (i.e. cheap), then it is...

The stock type mount (this goes for the engine and trans mounts), are two studs attached to two plates of metal with a rubber sandwich in between them.
This allow both compression and pull forces to be absorbed by the mount itself.
All these cheap-ass vendors who sell this crap built these mounts that can only handle compressor forces; they do not isolate the pull forces, as you're asking against the bolt / fastener.
What does this all mean?
You get increased vibration through this cheap-ass mount...
It could possibly damage something else, as now your mount does not isolate tension forces...

You get an inferior mount, because they are too cheap to build a proper mount...
Anyone can get a block of (insert fav...rubber, polyurethane, nylon, UHMW plastic, aluminum, hockey puck) and drill a hole in it and slap on a nut and bolt...

Fair enough. I had Banzai poly mounts in my last car. I actually really liked them. I didnt get too much extra vibration from them surprisingly. But they discontinued them. I guess if the Himni version ends up being bad i can always go back to stock or mazdaspeed version. But like i said, i really based the decision to buy more poly mounts off of my last experience with them.

I'll always value your words Ted.

I guess you're still running all factory mounts then Zach?

Im not laughing.... after all I've read about him I'm not surprised....

On another note.. i just finished the install of my short shifter. Yummy

I forgot how much i liked it. and it feels SOOOOOOO much better than the stock one. although its much stiffer. I guess i just need to drive it an break it in some. Or maybe add some more gear oil to the shifter hole? any suggestions on that?

I am, definitely all new components including the crossmember but as far as whether or no I got the stiffer version, I cant remember.

Yes, you should have added oil to the shifter housing.

ok cool. Yeah who knows... i may end up right there with you. We'll see. My guess is that since I'm not driving the car every day, even if it does wind up vibing more than i remember I won't be bothered.

Shoot.. it looked like it had enough in it. Looks like I'm making a trip to buy gear oil today then. Luckily its not hard to take apart all of that.

It doesn't need to be overflowing, there just needs to be some in there. . I assumed that with the cars age it would have been dry

agreed. According to mazdatrix it wasn't quite full enough but there was still a decent amount in there it seemed. The stock shifter didnt really feel notchy at all but it was like a floppy sausage. Now the new shifter is obviously nice and tight but also pretty notchy. Do you think adding more fluid will help that?

Actually, Mazda does not fill the shifter extension housing with any fluid from the factory...
So, all stock cars which have never had the transmission serviced should be dry.

IIRC, even the FSM does not instruct you to do so?

Most of us do - it doesn't hurt anything.
One negative is that if you DON'T have good shift boot covers (all THREE of them! - well, at least the most expensive, inner one with the metal flange), it's going to make a mess!

Good to know Ted! Luckily before I ordered the short shifter (which comes with the inner boot) I checked the condition of the other boots as well. They were gone. So I now have all new boots down there

Very interesting. . . I thought I had read somewhere (don't remember where though) that it needs oil poured in it. Good to know, thanks.

Just checked my old Haynes manual I use (I knew I wasn't making this up lol) and found that instruction. .
