[TinyT]

Thanks guys! Im ready whenever anyone is to do these so just let me or sam(Lag) know.

It's a bummer that I just sold the pump/pan from the S54 that I'm putting in the M3. I've gotta pick one of these up when I get the engine for my other E30.

The work all looks great! Keep it up!

I meant E34 pan in my original post. It was mentioned a couple times in this thread that this new subframe/pan combo would address the issue of how low the E34 pan sits when mounted. So how much more clearance do you gain?

[Teaguer]

I'm looking to start my S54 swap soon and this could come in handy. How much more clearance do you get by going with this subframe/pan combo over the E43 pan? You mentioned removing the rear sump for the S54 and going with something else. What sump do you use?

More clearance with what?
Basically you can't run a rear sump pan unless you notch into your firewall or you hack up your subframe.

The front part of the rear sump pan is shaved down or back and there is additional capacity added to the sides of the existing sump.

Hello all,

I apologize for the delay in getting some up-to-date pics. I got around to bolting it all up to the motor on the engine stand (car is at the body shop) so you can get an idea of how it all works together.







Overall the oil pan capacity went up slightly. It holds about 32.5 more cubic inches or .53 liters. So not a significant increase, but pretty good for removing such a large portion of the factory sump.

Hey guys, sorry for no updates on this. I still have to figure out the total oil capacity and get some pictures of it bolted up to the motor and in a car!

[TinyT]

thank you! I figured out how to weld the cast better as I went on so future pans will come out even better ;)

I will check with sam tomorrow on what the pan came out to as far as capacity. I believe he has the numbers.

[rThor432]

That looks like very nice work. The alu welding is impressive. Out of curiosity, what does the pan modification increase the oil capacity to?

[TinyT]

$450 if you send me yours. I will coat it and ship it back to you.

modified, and reinforced.

If you dont need it coated, $375

[bataangpinoy]

so what is the cost of having a subframe modified or purchasing just a subframe?

if we can run rear sump e36 pans on any of the m5x/s50-s52 i am more than willing to buy one.

Hey guys, just thought I'd chime in with a pic with the finished coated product. Can't wait to see how it looks on the car! :up:

Well we could put swaybar mounts on the front and back so you are future proofed, no big deal.
