S54/E153 mount compatibility?

406 Views 12 Replies 7 Participants Last post by  MIDSHIP89
I’m swapping out the S54 trans for an E153 finally, 8 years post gen4 swap. I noticed the rear bracket from the S54 doesn’t bolt up to the E153, so I’ll have to get that bracket. But what about the rubber side?

Are the front mount parts compatible? The bolt holes line up from the bracket to the transmission, but will there be an alignment issue with S54 hardware on the front of the E153?

The U-shaped bracket that bolts to the front of the transmission is the same part number NA or turbo.

The front and rear chassis side mounts (with the rubber in them) are different part numbers, but I think the only difference is the amount of rubber in the mount - the turbo mounts are more fully filled to provide better torque damping. So try your NA mounts on the front. If they don't line up, then you'll know the difference between the turbo and NA chassis side mounts is more than just the rubber insert.
rear mount the bolt hole sits about 6mm higher on the turbo than the NA
