Reinforced Subframe + Revshift Mounts

[Styleprojekt]

I may be a complete fool, but I cannot for the lifeof me figure out how to properly mount the Revshift motor mounts on a reinforced subframe.

I understand these mounts go on the slotted/oval hole on the subframe when using E36 motor mount arms...correct?


Next, how do you get this nut tightened? I tried various tools (there is zero room thanks to the reinforced plate) until I simply wedged a thick scredriver to keep the nut from sipnning. That only got the nut onto the mount half way. So I wanted to get the mount back out but it was impossible to reverse twist the nut off. The whole bottom plate/stud assembly started spinning seperately from the polyurethane part so i had no way to get the nut back off.

I found a picture from another guy's issue which is the same, so obviously the welded bracket + engine swap is a problem more common than just in my garage:



What mounts do people use with a reeinforced subframe? And how do you guys tighten the nut in that tiny little space?

Those nuts that go onto the mounts are quite beefy too so fitting even a thinned and trimmed 17mm wrench is impossible. Forget fitting a socket in there, the angle makes it impossible.

Since I couldnt get the Revshift mount back out I cut the damn thing out

I ran into that also. I just grinder out what what I needed to fit a socket in there.

Just curious but would this pertain to most aftermarket mounts? I.E. CSS, AKG, REV, etc... I'm about to weld on some reinforcement tabs on a spare subframe till I came across this.. If clearance is an issue, would it be wise to opt out for that curved piece or just grind it out till you can realistically work with it?

Thanks!

In stock form, the stud should go through the hole and the little nub on the stock mount goes into the slot. This allows you to use a socket through the hole in the reinforcement plate.

I used the flat doubler and the 'curved' outer piece. Even using the AKG mounts which use the hole not the slot. The hole in the reinf plate had to be opened up a bit for a socket to fit. The stud comes thru the subframe at an angle so just test fit for wrench clearance before reinstalling on car

I have mine in the round hole

Good lookin out!

What mounts are you using for that to work?
From what i am able to gather, all 24v Swapped applications, doesnt matter what mounts you use, will have to sit in the slotted outer hole, with the guide pin sittin in the inner "stock" location.

We ended up grinding quite a bit of material off to get anything to fit on that mount's nut...it was a PITA!

PS: Destroyed one of the REVSHIFT Mounts in the process, they are garbage in my opinion cause they dont have a guide pin...just round. Ended up using 535i mounts which fit way smoother

AKG mounts drop into stk location. Stud in round hole, locating nub in slot. Be sure to test fit any mount you use that the stud fits easily in the hole. It can help to ream the hole for a bit more clearance. Sound like you about have this ready to go. GL

Good info, i did not know that. Wish i would have known this before, but next time around I'll go for those bad boys then! Thanks!

Yeaaaah buddy, gotta stay true to the Euro community. We'll see how many more forums we run into eachother throughout the years as we acquire different projects/makes/models/builds :nice:

It goes in the round hole buddy.......

Actually thats wrong. Majority of swapped cars need to have the mounts sit on the outer holes due to the different motor mount arms being used. if you mount them on the stock inner holes, then the mounts wont sit flush
