Bump for this. I will post some more pictures of more pans and subframes leaving the shop. I also have 6 speed mounts almost ready for production as well as billet S54 fuel and vacuum rails! -
I stole this picture from Ryan G. He won 2nd place at bimmerfest this year!

It is a couple of weeks out from the time we get it and you are correct, the e34 pan is really close to the ground if your car is lowered!!!Leave a comment:

What is the turn around time on modifying the pan and sub frame? After looking at how low my car is and where the E34 pan would be, I'm not liking it.Leave a comment:

You are correct. And there is a possibility that the euro headers will with with this subframe without modification. I have not tested this but I hope that someone will be able to.

You also didn't mention the benefit of having the swaybar mounted in front of the subframe instead of behind it. With the Euro headers, swaybar clearance is almost none.To sum stuff up:
M50 pumps= some have lasted, some have failed, you can take your chances
E34 pan= fits without modification, just don't lower your car too much.
dual pickup pan/pump= modifications to the subframe and pan and will provide proper oiling (designed by BMW for these motors), more clearance and you can leave your firewall intact.
This set up= More oil capacity
These are the reasons that made me choose to go this route.Leave a comment:

I decided to go with this set up first and foremost because I have heard of M50 pump failures at the track. Here is one example that was detailed on s14.

I realize I am an exception, but it definitely can happen...
Because of experiences like this I am not confident in the M50 pump for the S54 if it has failed on the euro motors, and I say this because of the higher redline which is spinning that pump much further past where it was designed IMO. I am not willing to take that risk. Some might but I want to drive with confidence and wondering if I am the exception.
I also chose the dual pick up system because it is a better system. Plain and simple the design is better, if a single front sump was best BMW would have used that on all their M cars.
I do like the additional clearance that the S54 pan provides as well. here is a picture of the M50 pan in an E30 with the AKG motor mounts:

You can see that the m50 pan hangs past the subframe by quite a bit. With this set up the subframe is the lowest point.
