hey guys im thiiiiiis much closer to finishing up my fd...finatlly...but i am having some troubles with the poly mounts i just ordered...

a good friend of mine told me that some of the poly urathane mounts will not fit on the stock aluminum (intake side) mount bracket.

is this true? if so what can i do about it?...

definitely need some help with this one guys...

 

Depends on the mount kit

The Himini (sp) ones I purchased worked very well. They are bevel cut to fit the aluminum mount. You just have to remove the leftovers from the old mount and drill a centered hole and voila. Good to go.

 

I think the concern is more that the aluminum wont hold up to the stress put out by stiffer mounts. Thats why people change it out to the stronger steel one.

 

actually i was only wondering is what would i have to do if they didnt fit... i just didnt think about what you said...but you do make a really good safety precaution...where and how much can i get the steal bracket???

thats what the forum is for right?!!!

 

This is the same issue I had when replacing my motor mounts with Noltec Urethane's. My friend and I noticed the the Aluminum motor mount did not have a hole in the middle to install an aftermarket mount. So what I did, was buy a used steel motor mount on this forum for roughly about $40-50 shipped.
Trust me, buy the steel mount because its gonna be stronger and MUCH less of a hassle in the end. Heres some pictures of mine

 

not sure about the strength of the aluminum mount, but i got mine from www.rotaryengine.com and it is beveled to fit the aluminum mount very nicely. check this thread, i posted a couple pics. https://www.rx7club.com/3rd-generation-specific-1993-2002-16/poly-engine-mounts-832755/

 

sounds like a plan!

but are the left and the right interchangeable??? i know the steal mount is for the exhaust side and the aluminum for the intake side....but will i need to buy a specific mount for the intake side???

thanks for the info!

 

They are interchangeable.
