Can't square engine on mounts.

The 13b I have been trying to get running for a while now is not sitting in the bay square, it tilts to one side. I just tried g a proper 13b bracket in. but it is still leaning to one side and I can't line the mount up with bracket. Any suggestions would be helpful. All I have to lift the engine is a cross brace with a curved bolt, removing the engine is not possible as its already almost all hooked up.

You don't by any chance have the engine bracket on backwards, do you? No, not making fun.

Any pix?

Trans mount on right way around?

Engine bracket is in right, the trans bracket I believe is right. Does it matter that its my old 82 manual trans and bracket in an 84 gsl-se?

the engine should point to the drivers side, its for clearance for the exhaust to the steering box on RHD cars.

The problem seems to be that its cocked towards the passenger side, the bracket hole sits an inch or so in front of the drivers side mount bolt that sticks out of the puck. The passenger side was a pain, but it is in now.

Double check the trans bracket. If you have it bolted to the body then take the bolts out until the engine brace lines up.

A pic of the bay might give us a better idea of what is going on.

I can't really post a picture because of how difficult it is to see everything...

So I tried loosening the transmission mounts and they didn't really move so I tried to take the trans bracket off, now I can't get either the engine or trans brackets to line up...

Basically I just can't push the engine back far enough to mount up to the crossmember... I am using a 13B GSL-SE crossmember I know came from a 13b equipped GSL-SE that I found in the junkyard.

No matter what I try the engine is always an inch too far forward.

Honestly I am getting tired of there always being some small problem, its been 3 years and the best I can do is get it half together. I don't have the time to work on her anymore like I used to, now I have the money but no time and honestly I am tired of seeing it just sitting there like a half finished corpse. I'm pretty much ready to just have a flatbed haul it off somewhere.

Sorry about the rant, I am just very very frustrated with this... I told myself I'd get it up and running by the end of June and the entire time its been fighting me tooth and nail.

Alright, a little less stressed out now and a little more clear headed...

So here's a list of the parts and you guys tell me if something seems off:

-1984 GSL-SE Frame
-1982 Crossmember from a 12A engine
-Engine bracket from a 13B GSL-SE
-Transmission is a manual from a 1982 with transmission bracket from same vehicle.
-Engine is a S4 13B NA motor with GSL-SE Oil Pan and front cover

As far as I know from what I read on the forum, this should all fit together... but for some reason the entire engine/transmission assembly seems to sit like an inch too far foreward and when I just can't shove it back and more.

This is about the best picture that I can show to really explain what I am talking about, no matter how I lift the damn thing or shove it or twist it or what ever. It just seems to always be that much too far foreward.

I think the problem is that the crossmember you are using is from a 12A car.

I believe the difference isnt in the engine bracket, but the crossmember.


Either find a 13B crossmember, or get this:

I'm sorry, I mis wrote that.

I was considering the crossmember as the part that the LCA bolt to, Its not a subframe really.

I have an actual GSL-SE Crossmember for a 13B its what you see in the picture, I meant the other portion where the LCA mount to was from my old 12A.

Im not sure I understand what youre trying to say. I thought everything was pretty clear in your post..

To clarify: its the crossmember/subframe/whatever you want to call it that differs, not the engine bracket.



If you still have the 12A crossmember, the racingbeat part in my last post will allow you to bolt the 13B to the 12A crossmember.

Well I'll be damned... that would explain so much. I guess I'll have to set some cash aside and order the Racing Beat bracket. Thanks for the help, been at my wit's end on this project.

For the first 12a to 13b swap of mine, I welded some 1/4 plate to the stock mount feet(the ends of the piece that bolts to the engine), and drilled new holes.

20mm difference between 12A and the 13B.
This is not the best example but it should help ...its the cheap way.

I actually used that thread to notch my 12A bracket, but it didn't come out right so the engine sat funny in the bay.

Tried the RB bracket and fit like a charm, still tilted a little to the driver's but that was noted as being normal.

On a side note, has the shifter on the FBs always been offset towards the passenger? I mean when you are staring down the open hole in the tunnel you can see the tailshaft is along the passenger side area more than the center of the hole.
