N52 oil pan design for Z4 engine arm based swap

[projectJTv4]

Your dipstick drawing looks different than what I'm using and looking at mine again I think the dot is probably the full mark?! I was using the top cutout, so apparently I'm closer to the half mark at 5.5 quarts. Sorry if that's what's causing your grief, I'll update my other post with this picture.

The top of the "aftermarket" indention is where mine was with 5.5 quarts. I plan to fill it until it reaches the top of the cutout, hopefully about 6 quarts, that should keep the oil just at or slightly below the top of the baffle.

I wouldn't get hung up on the 5.5 number, the more oil the better. I think the full mark to parallel with the top of the baffle will be safe, I don't know how high is too much. Hoveringuy might have some better input.

You could just make a new mark on the dipstick and send it, as is. Save quite a bit of work.

Ahh that makes sense, thanks!

And you are correct, I actually modeled out the M20 dipstick and not the M50. I need to update my model, thanks for pointing that out.



I was able to rotate the dipstick while in the guide tube and mark a sharpie mark, which happens to be just a little bit above the little domed feature.

Removed the support cross members to bolt directly on to the block upside down.

Max attachments per post is 5...

Ignore the dusty inside :P



Baffle is also tacked together



Looks like I have some slight interference in these areas at the moment.






Oh and I have access to a lathe now but it is not convenient to get to. I cut my oil pick up o-ring groove too shallow so it won't fit into the oil pump, oops.

Yes, Thanks for that idea! I shipped it off to projectJTv4 today. He'll pass it on to the next guy who needs it when he's done.

Bed plate is now in the possession of Yo.goob

I bet the gasket will take care of that interference, don't forget to account for it for pickup depth.

Glad to see you got the bedplate on to the next guy!

1) I just got some photos from a guy that received his SendCutSend pan package yesterday; he even has a spare block to bolt it to while he welds it. The wild part is, the N52 is going into an FR86!

2) This is how much clearance my pan has. I just finished fabricating an undertray and it sits flush against the bottom of the pan. I did some CAD that worked-out really nice for attaching the front of it, hangs off the core support and bolts in where the stock oil cooler mount goes, it's strong A.F. and comes off with a few screws. Hit me up for the CAD if you're interested...

Will the car be faster? quieter? overheating? Track season only a few months away...

An FR86 would be a great landing spot for an N52! I'm glad to see this pan being used in other platforms!

Perhaps a ridiculous question, but has anyone considered keeping the E90's Oil condition/level sensor?

my E30 had the 4 banger M42 with no oil level sensor like the M20, so im at a bit of a crossroads in terms of just doing a delete of the E90 oil sensor and using just a dipstick tube or figuring out a way of making the E90's sensor work with the SCS oil pan and fidgeting with that design problem?

I'm not sure how valuable it would be without the E90 cluster. Probably better to put an M20 one in? No expert though. I have a dipstick.

It's a lot of complication in the pan where there's not a lot of room for recessing that sensor. I added an M50 dipstick that's way more accurate than the electronic sensor and I change my oil every season anyway. The ONLY thing I miss is that it also reads oil temperature.

I added the M20 sensor only to have my check panel work. I confirmed it works with hoveringuy's pan today. Wasn't working at first, level float or whatever is inside wasn't sliding properly. Soaked/flushed with gas and degreaser, should've seen the crap came out from 30 years of use. Re-installed and works properly now. I have 3 flanges left, ordered enough to prevent paying the minimum order fee with SCS. They have some surface rust from but should cleanup fine. I will mail if anyone needs one, just weld it slow. I warped one on my first try. I also have the CAD file, if someone wants that. Not much of a contribution but took me forever to draw regardless, just need to select the option to have M6 studs pressed in when you order.

Panici The front bracket is the "magic". it bolts to the core support and provides the fingers that slide into the receiver on the tray, which is a stack of 0.100" aluminum (see post above). The rear has M6 pan head bolts that go into a plate that's bolted through the power steering rack bolts.

So, taking it on and off is barely an inconvenience, but at the same time it's strong A.F. If I ever do mangle it I won't be taking the core support out with it, I'll just order new pieces from SCS.

I'm working on an aluminum version of the pan, just because... The fun part is that hopefully I can solve the oil pickup issue once and for all. Instead of "figure it out" it will be 3d printed and will have much better pickup placement.

I have the 3D printed aluminum prototype on-order and the delivered price for one was $100. It will mate with standard tubing.

I can't believe this didn't occur to me... great work!

It got kicked-back because my file had "too many sharp edges".... I guess that happens during conversion to STL, but the STEP file is fine so off to printing....
