E30 s54 swap A/C comp to radiator clearance?

Using the new style (thinner) z3m radiator and the end tank rests directly on the compressor. Couldn't imagine the thicker core fitting.

Anyone else have this issue? I'll figure a way around it, just thought someone had to come across it before.

E30s don't have serpentine belts... so I'm guessing no.

E46m3 engine and compressor.

Ended up moving the engine back 3/4" which makes the head smash the firewall insulation. Will see about NVH, might be an issue with the m5 OEM mounts, but the owner was very against solid mounts.

How exactly did you move the engine back 3/4"?

I think most people use the E36 compressor. Maybe it would have more clearance?

I used a large pry bar and shimmed it in place for now. Used a 3/4" piece of wood between the oil pan and sub frame. The compressor clutch now has about 1/4".

Not sure how the e36 compressor would make any difference as the belt will be in the same location and most AC clutches are similar in size. I have some at the shop. Took the day off today for a change, but can verify when I go back in.

I verified today the e36 (at least OBD 2cars) have a viscous coupler clutch, NON magnetic in the e36 (don't even use the same signal). Same EXACT dimensions as the e46 compressor clutch, and obviously same belt placement since they both work on the water pump and crank pulley.

What mounts/sub frame/drive shaft etc did you use??

....just an FYI, the e30 clutch with typical magnetic clutch makes another ~1/4" (~7mm) room. Problem is kick on signals. Perhaps I need to verify, but it seems to me, y'all are doing something different then I am, grrrrr

This guy is running the E36 compressor as well.

I think its the radiator thats eating up the space. The mishimoto rad is a bit narrower because it doesn't have the plastic end tanks like the factory ones do.

It's definitely the radiator. The s54 block is physically the same size and have done my fair share of AC in swaps, but always just used the standard e36/e30 radiator or Mishimoto equivalent.
