N52 oil pan design for Z4 engine arm based swap

[hoveringuy]

Group Buy?

I mean, the pan is about $220 from SendCutSend. Anyone thats a decent fabricator could do a run and make a few bucks. Would be way more efficient to do more than 1 at a time!

The baffle just snaps together.

Pan, version 2.0, complete! I ran it last night and warmed up the motor, let it sit overnight and no leaks anywhere. I'm happy with the fit, it has slightly more clearance to the rack, has more capacity at 5 3/4 Qts and has a perfect dip stick. Still-awesome ground clearance.

As a sanity check, I submitted an oil sample to Blackstone last month and also pulled my big end bearings while I'm swapping the pan to the new design. Mind you, the old pan wasn't optimized for track use but it has done its job well! -Zero- corrosion in the pan itself and the Cosworth oil flaps are still perfect.

The motor has probably 2000 track miles now and 90,000 overall. The bearings were beginning to show some wear but probably typical for a motor with 90,000 miles. The oil report was clean.

Carry on!

Complete. Final capacity is 5 3/4 Qts.
E36 dipstick.

when will these be available?

The main pan is done. I can send you the .DXF whenever, or I don't know if I can share my SendCutSend project which already has the thickness and bends specified. I've made two small changes to the pan for extra bolt clearance at the corners but those are basic metalworking that don't require CAD changes. I made one adjustment to the flange by adding support braces across the middle; welding shrinkage likes to pull the flanges together and hopefully these cutaways will help it hold position during fabrication. I had to ream-out the holes on mine a few mm.

The baffle is also done, just need to validate the few changes I made when the stainless version arrives in two days. Those .DXF files are also available if you want to see them.

The "SendCutSend" pan is coming along nicely... Initial baffle design fits great, I've made some small adjustments to it and re-ordered in 0.030 stainless. My analysis shows that the pickup position will be submerged indefinitely at 1G of left or right turns and can sustain 1.5Gs of braking. The baffles increase those margins for maybe 8 seconds before the oil goes where gravity says it will...

Awesome update! I'll be needing one of these soon...

My SendCutSend "kit" arrived. I am mostly very pleased, it fits together like it was designed in CAD or something (where CAD doesn't stand for Cardboard Assisted Design....)

It looks kinda like the rendering.

Except for the fact that some idiot specified the wrong bend angle on one piece it's ready to weld together. All of this was $240

Nice work Steve. Looking forward to seeing the final result.

I've pulled the trigger on ordering bent metal for another pan. If it snaps together into a pan I'll be a little surprised, but CAD doesn't lie, right?

I started work on the SendCutSend version of this pan. Ideally, you can have the pre-bent pieces delivered and just weld along the seams. Plus, it will have some improvements over the successful version 1 pan. Slightly more capacity and even better oil control.

I hope so! I am using a spare N54 block as a welding jig, for alignment of the oil pump pickup etc.

Any updates on this? It’ll fit an N54, correct?
